 <p>现在我们就可以创建一个.order文件，在文件里面对符号进行排序，把应用启动时刻调用的方法排到前面，这样就可以减少PageFault次数从而减少启动时长，具体如何创建Order文件可以参考上一篇文章：<a href="https://codersunny.com/posts/23c5d0e7/">iOS重学之启动优化（二）- 二进制重排</a> 。</p>
 <h2 id="总结-3">总结</h2>
 <p>关于用Clang插桩的方法去解决二进制重排如何排序的问题到这里就基本结束了，当然也遗留了一些问题：比如如果项目里面有Swift、循环等，这个时候我们的Clang应该如何去做进一步的优化，大家有兴趣的可以自己去研究一下。</p>

 <p>离屏渲染的处理仅仅是我们日常所关注的性能中的其中一个点，在处理的时候也要根据具体场景具体分析，要注意并不是所有的离屏渲染都是必须要去避免的，开辟额外的帧缓存虽然有一定的性能损耗，但是保存渲染结果并进行最终的视图显示也是为了保持视图的流畅性。</p>

 <p>是不是项目变大了做包体积优化才有意义？</p>
 <p>绝对不是，包体积优化应该是一种习惯而不是等到包体积变得很大了才去思考做优化，应该是只要觉得有优化的空间就去做优化。</p>
 <p>如果打出来的ipa包比较小，说明我们的历史负担不严重，俗话说船小好掉头而且编译的速度也快，试错成本也低，恰恰才是该优化的时候，优化总结出来的教训落地到文档形成一种规范，后续开发时也能时刻引起注意，这样对于开发来说是最好的。</p>

+<p>Hexo是一个快速、简洁且高效的博客框架，具体可以见<a href="https://hexo.io/zh-cn">Hexo官网</a>，它在github上的star数现在已经到34.7k，Hexo主要有以下特点：</p>
+<ol>
+<li>超快速度：Node.js所带来的超快生成速度，可以让上百个页面在几秒内完成渲染。</li>
+<li>支持Markdown：Hexo 支持 GitHub Flavored Markdown 的所有功能，甚至可以整合 Octopress 的大多数插件。</li>
+<li>一键部署：只需一条指令即可部署到 GitHub Pages, Heroku 或其他平台。</li>
+<li>插件或可扩展性：强大的 API 带来无限的可能，与数种模板引擎（EJS，Pug，Nunjucks）和工具（Babel，PostCSS，Less/Sass）轻易集成。</li>
+</ol>

+<h2 id="修改网站主题">修改网站主题</h2>
+<p>Hexo框架默认的是landscape主题，Hexo上有三百多种主题，大家可以上<a href="https://hexo.io/themes/">Hexo官网</a>选择自己喜欢的主题，我这里以butterfly为例：</p>
+<h3 id="下载butterfly主题">下载butterfly主题</h3>
+<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">// 下载butterfly</span><br><span class="line">git <span class="built_in">clone</span> https://github.com/jerryc127/hexo-theme-butterfly.git themes/butterfly</span><br></pre></td></tr></table></figure>

+<p>我们下载的主题都存放在Blogs/themes文件夹下：</p>

+<h3 id="修改项目配置文件">修改项目配置文件</h3>
+<p>主题下载下来之后，我们需要在项目配置文件_config.yml里面修改我们的主题：</p>

+<p>把默认的<code>landscape</code>修改为我们下载好的主题 <code>butterfly</code></p>
+<h3 id="重新生成项目">重新生成项目</h3>
+<p>这时候再执行我们Hexo三连：</p>
+<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">// 清理项目缓存</span><br><span class="line">hexo clean</span><br><span class="line"></span><br><span class="line">// 重新生成项目</span><br><span class="line">hexo g</span><br><span class="line"></span><br><span class="line">// 本地启动项目</span><br><span class="line">hexo s</span><br></pre></td></tr></table></figure>
+<p>Tips：重新生成项目和本地启动项目可以合并：<code>hexo g &amp; hexo s</code></p>
+<p>再次打开项目，效果图如下：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_12.png" alt="20220509_12"></p>
+<p>哈哈哈哈，惊不惊喜，意不意外，这是个什么鬼东西？？？</p>
+<p>别慌，发现问题 - 找到问题 - 分析问题 - 解决问题：</p>
+<p>原因其实也很简单，我们没有安装pug和stylus的渲染器，执行如下命令：</p>
+<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">// 在Blogs目录下 安装pug 和 stylus渲染器</span><br><span class="line">npm install --save hexo-renderer-jade hexo-generator-feed hexo-generator-sitemap hexo-browsersync hexo-generator-archive</span><br></pre></td></tr></table></figure>

+<p>到这里，我们的主题修改就完成了，后期我们可以根据自己的需要去修改butterfly的配置文件，让我们的博客网站更加个性化。</p>
+<p>下一篇文章我将说说如何修改主题让我们的博客网站更具个性化。</p>
+<p>关于Hexo搭建博客到这里就讲得差不多了，下面我们就想怎么把博客部署到Github上。</p>
+<h2 id="部署博客到Github">部署博客到Github</h2>
+<p>首先，你得要有一个自己的Github账号吧，我相信99.99%的开发者都是有Github账号的，如果你是那0.01%，请前往<a href="https://github.com/">Github</a>自行注册。</p>
+<h3 id="创建仓库">创建仓库</h3>
+<p>在Github里创建一个存放博客项目的仓库，操作如下：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_14.png" alt="20220509_14"></p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_15.png" alt="20220509_15"></p>
+<p>这里有两个注意点：</p>
+<ol>
+<li>仓库的名称必须与你Github账号名相同</li>
+<li>仓库必须以<code>gitHub.io</code>结尾</li>
+</ol>
+<p>比如你Github账号名叫：<code>zhangsan</code>，那你新建的这个仓库名就叫：<code>zhangsan.github.io</code></p>
+<p>创建之后，我们就有了一个存放博客项目仓库：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_16.png" alt="20220509_16"></p>
+<h3 id="安装Hexo部署插件">安装Hexo部署插件</h3>
+<p>进入到Blogs目录下，安装部署插件：</p>
+<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">cnpm install --save hexo-deployer-git</span><br></pre></td></tr></table></figure>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_17.png" alt="20220509_17"></p>
+<h3 id="修改项目配置文件-2">修改项目配置文件</h3>
+<p>好了，万事俱备，只欠修改_config.yml文件了，打开_config.yml文件，拖拽到最后，修改文件：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_18.png" alt="20220509_18"></p>
+<p>修改为：</p>

+<p>注意：repo为你刚创建的Github项目的地址，如果你是使用的vim打开的_config.yml，记得修改了要:wq保存退出</p>
+<h3 id="重新生成项目-2">重新生成项目</h3>
+<p>清理项目缓存：</p>
+<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo clean</span><br></pre></td></tr></table></figure>
+<p>重新生成博客：</p>
+<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo g</span><br></pre></td></tr></table></figure>
+<p>部署到云端（Github）：</p>
+<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo d</span><br></pre></td></tr></table></figure>
+<p>注意：这里每次使用<code>hexo d</code>部署到Github为了安全都要求输入账号密码，如果你不希望每次都输入账号密码，可以跟博主一样设置Github的SSH Keys，以后每次发布到Github就不需要输入账号密码了。</p>

+<p>基本上到这里，属于我们自己的博客就搭建完成啦，撒花🎉🎉🎉～，整个搭建流程如果不出错半个小时之内其实是可以搞定的，但是这路哪里那么好走呢，每个人去搭建的过程中或多或少都会遇到一些问题，我自己在搭建的过程中也碰到了一些问题，我会抽空把遇到的问题详细整理出来，希望能够帮助大家如果要搭建博客的时候少踩点坑。</p>
+<p>嘻嘻嘻，都看到这里了，不要吝啬你的小星星嘛，为博主点个赞呐～</p>

-<p>Hexo框架默认的是landscape主题，Hexo上有三百多种主题，大家可以上<a href="https://hexo.io/themes/">Hexo官网</a>选择自己喜欢的主题，我这里以butterfly为例：</p>

-<p>把默认的<code>landscape</code>修改为我们下载好的主题 <code>butterfly</code></p>
-<h3 id="重新生成项目">重新生成项目</h3>
-<p>这时候再执行我们Hexo三连：</p>
-<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">// 清理项目缓存</span><br><span class="line">hexo clean</span><br><span class="line"></span><br><span class="line">// 重新生成项目</span><br><span class="line">hexo g</span><br><span class="line"></span><br><span class="line">// 本地启动项目</span><br><span class="line">hexo s</span><br></pre></td></tr></table></figure>
-<p>Tips：重新生成项目和本地启动项目可以合并：<code>hexo g &amp; hexo s</code></p>
-<p>再次打开项目，效果图如下：</p>

-<p>哈哈哈哈，惊不惊喜，意不意外，这是个什么鬼东西？？？</p>
-<p>别慌，发现问题 - 找到问题 - 分析问题 - 解决问题：</p>
-<p>原因其实也很简单，我们没有安装pug和stylus的渲染器，执行如下命令：</p>
-<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">// 在Blogs目录下 安装pug 和 stylus渲染器</span><br><span class="line">npm install --save hexo-renderer-jade hexo-generator-feed hexo-generator-sitemap hexo-browsersync hexo-generator-archive</span><br></pre></td></tr></table></figure>

-<p>到这里，我们的主题修改就完成了，后期我们可以根据自己的需要去修改butterfly的配置文件，让我们的博客网站更加个性化。</p>
-<p>下一篇文章我将说说如何修改主题让我们的博客网站更具个性化。</p>
-<p>关于Hexo搭建博客到这里就讲得差不多了，下面我们就想怎么把博客部署到Github上。</p>
-<h2 id="部署博客到Github">部署博客到Github</h2>
-<p>首先，你得要有一个自己的Github账号吧，我相信99.99%的开发者都是有Github账号的，如果你是那0.01%，请前往<a href="https://github.com/">Github</a>自行注册。</p>
-<h3 id="创建仓库">创建仓库</h3>
-<p>在Github里创建一个存放博客项目的仓库，操作如下：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_14.png" alt="20220509_14"></p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_15.png" alt="20220509_15"></p>
-<p>这里有两个注意点：</p>
-<ol>
-<li>仓库的名称必须与你Github账号名相同</li>
-<li>仓库必须以<code>gitHub.io</code>结尾</li>
-</ol>
-<p>比如你Github账号名叫：<code>zhangsan</code>，那你新建的这个仓库名就叫：<code>zhangsan.github.io</code></p>
-<p>创建之后，我们就有了一个存放博客项目仓库：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_16.png" alt="20220509_16"></p>
-<h3 id="安装Hexo部署插件">安装Hexo部署插件</h3>
-<p>进入到Blogs目录下，安装部署插件：</p>
-<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">cnpm install --save hexo-deployer-git</span><br></pre></td></tr></table></figure>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_17.png" alt="20220509_17"></p>
-<h3 id="修改项目配置文件-2">修改项目配置文件</h3>
-<p>好了，万事俱备，只欠修改_config.yml文件了，打开_config.yml文件，拖拽到最后，修改文件：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_18.png" alt="20220509_18"></p>
-<p>修改为：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220509/20220509_19.png" alt="20220509_19"></p>
-<p>注意：repo为你刚创建的Github项目的地址，如果你是使用的vim打开的_config.yml，记得修改了要:wq保存退出</p>
-<h3 id="重新生成项目-2">重新生成项目</h3>
-<p>清理项目缓存：</p>
-<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo clean</span><br></pre></td></tr></table></figure>
-<p>重新生成博客：</p>
-<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo g</span><br></pre></td></tr></table></figure>
-<p>部署到云端（Github）：</p>
-<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo d</span><br></pre></td></tr></table></figure>
-<p>注意：这里每次使用<code>hexo d</code>部署到Github为了安全都要求输入账号密码，如果你不希望每次都输入账号密码，可以跟博主一样设置Github的SSH Keys，以后每次发布到Github就不需要输入账号密码了。</p>
-<h3 id="访问云端博客主页">访问云端博客主页</h3>
-<p>访问地址：<a href="https://happycodersunny.github.io/">https://happycodersunny.github.io</a></p>

-<h2 id="最后-4">最后</h2>
-<p>基本上到这里，属于我们自己的博客就搭建完成啦，撒花🎉🎉🎉～，整个搭建流程如果不出错半个小时之内其实是可以搞定的，但是这路哪里那么好走呢，每个人去搭建的过程中或多或少都会遇到一些问题，我自己在搭建的过程中也碰到了一些问题，我会抽空把遇到的问题详细整理出来，希望能够帮助大家如果要搭建博客的时候少踩点坑。</p>
-<p>嘻嘻嘻，都看到这里了，不要吝啬你的小星星嘛，为博主点个赞呐～</p>

-    <content><![CDATA[<h2 id="如何拥有自己的域名">如何拥有自己的域名</h2>
-<p>在<a href="https://happycodersunny.github.io/2022/05/09/%E3%80%90Hexo%E3%80%91Mac%20OS%E4%B8%8A%E4%BD%BF%E7%94%A8Hexo%20+%20Github%E6%90%AD%E5%BB%BA%E5%8D%9A%E5%AE%A2%E6%95%99%E7%A8%8B/">这篇文章</a>中我们利用Hexo和Github搭建了自己的博客，搭建出来的博客地址格式都是：<code>https://+Github博客仓库名.github.io </code></p>
-<p>比如我的博客地址就是：<code>https://happycodersunny.github.io</code></p>
-<p>是不是觉得不好看，大家的网址都长一样，好像是流水线上生产出来的一样，那么怎么替换成自己的域名显得更个性化呢？</p>
-<h2 id="购买域名">购买域名</h2>
-<p>首先一个普通的域名也不贵，你可以上XX云买一个自己喜欢的域名，我这里以阿里云为例：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_01.png" alt="20220512_01"></p>
-<p>在购买的时候需要你实名，就按照要求填写相关信息即可，填写之后需要一会的审核时间，一般还是很快的。</p>
-<p>如果你实在是不想花钱买域名也可以<a href="%5Bhttp://freenom.com%5D(https://link.zhihu.com/?target=http%3A//freenom.com/)">在这里</a>免费注册一个域名，具体注册和解析步骤可以参考<a href="https://www.zhihu.com/question/31377141/answer/2266363145">知乎文章</a>。</p>
-<h2 id="域名解析">域名解析</h2>
-<p>购买域名之后我们还需要对域名进行解析之后才能使用。</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_02.png" alt="20220512_02"></p>
-<p>在这里面添加两条记录如上所示。</p>
-<p>记录类型为A的四个记录值是Github page官网说的四个记录值，好多文章写的192开头的两个已经不是最新的了，大家最好还是对照<a href="https://docs.github.com/en/pages/configuring-a-custom-domain-for-your-github-pages-site/managing-a-custom-domain-for-your-github-pages-site">Github Pages</a>进行设置，也可以使用<code>ping xxx.github.io</code>来验证一下。</p>
-<p>记录类型为CNAME的记录值必须是<code>xxx.github.io</code>。</p>
-<h2 id="添加CNAME文件">添加CNAME文件</h2>
-<p>一、在<code>Github</code>上博客项目里按照下面步骤配置自定义域名：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_03.png" alt="20220512_03"></p>
-<p>这里需要注意的是：我们需要勾选<code>Enforce HTTPS</code>，这样以后访问我们的博客才安全不会提示网站链接不安全的问题，<code>Github Pages</code>官网上说勾选这个之后一般需要等待24h才可以正常使用，不过有时候也快，我这个等了两三分钟就可以了。</p>
-<p>二、配置完成之后，博客项目下会多一个<code>CNAME</code>文件，里面的内容就是我们上面配置的自定义域名：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_04.png" alt="20220512_04"></p>
-<p>三、检查博客根目录下的source文件夹下是否有一个CNAME文件，如果还是没有请自行在<code>/source</code>目录下新添加一个CNAME文件，内容跟上面一样还是填写自己购买的域名，保存。</p>
-<h2 id="修改博客配置文件">修改博客配置文件</h2>
-<p>打开我们本地博客目录下的<code>_config.yml</code>文件：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_05.png" alt="20220512_05"></p>
-<p>将里面的url替换成我们自己的即可。</p>
-<p>执行如下命令：</p>
-<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo clean</span><br><span class="line">hexo g</span><br><span class="line">hexo d</span><br></pre></td></tr></table></figure>
-<p>再次运行博客：</p>
-<p>如果不添加<code>HTTPS</code>，网站左上角会提示该网站不安全：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_06.png" alt="20220512_06"></p>
-<p>正常添加<code>HTTPS</code>，网站左上角会有一个锁头标志，说明这个网站是安全的：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_07.png" alt="20220512_07"></p>
-<p>这样我们就把自己购买的域名用上了，也使自己的网站更具个性化一点。</p>
-<h2 id="最后-6">最后</h2>
-<p>嘻嘻嘻，都看到这里了，不要吝啬你的小星星嘛，为博主点个赞呐～</p>

+<p>在<a href="https://happycodersunny.github.io/2022/05/09/%E3%80%90Hexo%E3%80%91Mac%20OS%E4%B8%8A%E4%BD%BF%E7%94%A8Hexo%20+%20Github%E6%90%AD%E5%BB%BA%E5%8D%9A%E5%AE%A2%E6%95%99%E7%A8%8B/">这篇文章</a>中我们利用Hexo和Github搭建了自己的博客，搭建出来的博客地址格式都是：<code>https://+Github博客仓库名.github.io </code></p>
+<p>比如我的博客地址就是：<code>https://happycodersunny.github.io</code></p>
+<p>是不是觉得不好看，大家的网址都长一样，好像是流水线上生产出来的一样，那么怎么替换成自己的域名显得更个性化呢？</p>
+<h2 id="购买域名">购买域名</h2>
+<p>首先一个普通的域名也不贵，你可以上XX云买一个自己喜欢的域名，我这里以阿里云为例：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_01.png" alt="20220512_01"></p>
+<p>在购买的时候需要你实名，就按照要求填写相关信息即可，填写之后需要一会的审核时间，一般还是很快的。</p>
+<p>如果你实在是不想花钱买域名也可以<a href="%5Bhttp://freenom.com%5D(https://link.zhihu.com/?target=http%3A//freenom.com/)">在这里</a>免费注册一个域名，具体注册和解析步骤可以参考<a href="https://www.zhihu.com/question/31377141/answer/2266363145">知乎文章</a>。</p>
+<h2 id="域名解析">域名解析</h2>
+<p>购买域名之后我们还需要对域名进行解析之后才能使用。</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_02.png" alt="20220512_02"></p>
+<p>在这里面添加两条记录如上所示。</p>
+<p>记录类型为A的四个记录值是Github page官网说的四个记录值，好多文章写的192开头的两个已经不是最新的了，大家最好还是对照<a href="https://docs.github.com/en/pages/configuring-a-custom-domain-for-your-github-pages-site/managing-a-custom-domain-for-your-github-pages-site">Github Pages</a>进行设置，也可以使用<code>ping xxx.github.io</code>来验证一下。</p>
+<p>记录类型为CNAME的记录值必须是<code>xxx.github.io</code>。</p>
+<h2 id="添加CNAME文件">添加CNAME文件</h2>
+<p>一、在<code>Github</code>上博客项目里按照下面步骤配置自定义域名：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_03.png" alt="20220512_03"></p>
+<p>这里需要注意的是：我们需要勾选<code>Enforce HTTPS</code>，这样以后访问我们的博客才安全不会提示网站链接不安全的问题，<code>Github Pages</code>官网上说勾选这个之后一般需要等待24h才可以正常使用，不过有时候也快，我这个等了两三分钟就可以了。</p>
+<p>二、配置完成之后，博客项目下会多一个<code>CNAME</code>文件，里面的内容就是我们上面配置的自定义域名：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_04.png" alt="20220512_04"></p>
+<p>三、检查博客根目录下的source文件夹下是否有一个CNAME文件，如果还是没有请自行在<code>/source</code>目录下新添加一个CNAME文件，内容跟上面一样还是填写自己购买的域名，保存。</p>
+<h2 id="修改博客配置文件">修改博客配置文件</h2>
+<p>打开我们本地博客目录下的<code>_config.yml</code>文件：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_05.png" alt="20220512_05"></p>
+<p>将里面的url替换成我们自己的即可。</p>
+<p>执行如下命令：</p>
+<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo clean</span><br><span class="line">hexo g</span><br><span class="line">hexo d</span><br></pre></td></tr></table></figure>
+<p>再次运行博客：</p>
+<p>如果不添加<code>HTTPS</code>，网站左上角会提示该网站不安全：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_06.png" alt="20220512_06"></p>
+<p>正常添加<code>HTTPS</code>，网站左上角会有一个锁头标志，说明这个网站是安全的：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/20220512/20220512_07.png" alt="20220512_07"></p>
+<p>这样我们就把自己购买的域名用上了，也使自己的网站更具个性化一点。</p>

-    <url>/posts/1bf7fb0b/</url>
-    <content><![CDATA[<h2 id="写在前面-9">写在前面</h2>
-<p>本文主要是记录一下如何越狱，博主这里指的是不完美越狱，博主这里越狱的手机是：iPhone5s  iOS12.5.6。</p>
-<p>首先，你需要有：iPhone手机、Mac电脑，保证Mac和手机上都有<a href="https://www.i4.cn/">爱思助手</a>。</p>
-<h2 id="越狱的简单介绍">越狱的简单介绍</h2>
-<h3 id="什么是越狱？">什么是越狱？</h3>
-<p>越狱：iOS jailbreak，利用iOS系统的漏洞获取iOS系统的最高权限，解开之前的各种限制。</p>
-<div class="note red no-icon flat"><p><strong>越狱的优点</strong>：</p>
-<p>1、可以打造个性化、与众不同的iPhone</p>
-<p>2、可以修改APP的一些默认行为</p>
-<p>3、可以自由安装非App Store来源的App</p>
-<p>4、灵活管理文件系统，让iPhone可以像U盘那么灵活</p>
-<p>5、给开发者提供了逆向功能的环境</p>
-<p><strong>越狱的缺点</strong>：</p>
-<p>1、越狱的手机不予保修</p>
-<p>2、比较耗电，越狱之后的手机会常驻一些进程，耗电速度约提升10%</p>
-<p>3、不再受iOS系统默认的安全保护，容易被恶意软件攻击，个人隐私有被窃取的风险</p>
-<p>4、如果安装了不稳定的插件，容易让系统不稳定、变慢或者出现“白苹果”现象</p>
-</div>
-<h3 id="完美越狱和不完美越狱">完美越狱和不完美越狱</h3>
-<p>完美越狱：手机在越狱之后可以正常关机和重启。</p>
-<p>不完美越狱：手机不能关机或重启，关机之后可能会出现越狱软件<code>Cydia</code>等无法打开需要重新越狱，严重甚至出现“白苹果”现象。</p>
-<h3 id="Cydia">Cydia</h3>
-<p>Cydia：可以理解为是越狱之后的&quot;App store&quot;，可以在Cydia里面安装一些第三方软件、补丁、插件等。</p>
-<div class="note red no-icon flat"><p><strong>Cydia安装软件的步骤</strong>：</p>
-<p>1、添加软件源（不同的软件软件源可能不一样）（Cydia - 软件源 - 编辑 - 添加 - 输入软件源地址）</p>
-<p>2、进入软件源 - 找到对应的软件开始下载</p>
-</div>
-<p>有的插件安装完成之后会要求重启SpringBoard，SpringBoard可以理解为iOS的桌面。</p>
-<h2 id="如何越狱">如何越狱</h2>
-<p>用数据线连接上手机和电脑，打开【爱思助手】- 工具箱 - 一键越狱：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/1.png" alt="1"></p>
-<p>会显示当前手机系统、型号、是否越狱等信息：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/2.png" alt="2"></p>
-<p>博主这里选择Checkra1n进行越狱，出现如下界面：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/3.png" alt="3"></p>
-<p>点击Start，按照如下操作开始下载越狱软件CheckRa1n：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/4.png" alt="4"></p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/5.png" alt="5"></p>
-<p>安装完Checkra1n之后，手机上会有一个checkra1n的软件，打开它开始安装Cydia软件：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/6.png" alt="6"></p>
-<p>安装完Cydia之后，手机桌面会多一个软件如下：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/7.png" alt="7"></p>
-<p>此时连接爱思助手，会发现顶部关于手机的信息会发生变化：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/8.png" alt="8"></p>
-<p>会看到上面提示我们去安装AFC2和AppSync两个插件，这两个插件具体有何用处如下：</p>
-<div class="note red no-icon flat"><p>AFC2：可以保证能够访问整个iOS的文件系统。</p>
-<p>AppSync：保证绕过验证随意安装、运行破解的ipa包。</p>
-</div>
-<p>点击安装AFC2会提示我们如何安装，大家按照自己手机的系统来安装，Cydia - 搜索Apple File… - 安装：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/9.png" alt="9"></p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/10.png" alt="10"></p>
-<p>安装完成之后，点击重启SpringBoard即可。</p>
-<p>此时连接Mac和手机，爱思助手顶部信息如下：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/11.png" alt="11"></p>
-<p>这时我们如果直接点击【安装AppSync】可能会报如下错误：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/12.png" alt="12"></p>
-<p>不用理会，直接在Cydia - 添加软件源：<a href="http://cydia.angelxwind.net">cydia.angelxwind.net</a>，如下图所示：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/13.png" alt="13"></p>
-<p>选择我们刚添加的源 - 插件 - 搜索AppSync - 安装：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/14.png" alt="14"></p>
-<p>安装完成之后同样需要重启SpringBoard，在Cydia - 已安装 里面可以看到我们刚安装的两个插件：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/15.png" alt="15"></p>
-<p>两个都安装成功之后，我们会看到爱思助手顶部信息发生变化，告诉我们该设备已越狱：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/16.png" alt="16"></p>

-    <url>/posts/67d22871/</url>
-    <content><![CDATA[<h2 id="写在前面-12">写在前面</h2>
-<p>关于<code>Block</code>的底层原理相关东西，需要了解的东西比较多，所以博主这里打算用两篇文章来详细分析一下OC里面的<code>Block</code>，这是第一篇，内容主要包含：</p>
-<ul>
-<li>Block的基本使用</li>
-<li>Block的底层数据结构</li>
-<li>Block对变量的捕获</li>
-<li>Block的类型</li>
-</ul>
-<p>好了，废话少说，现在跟着博主开始从头了解Block吧。</p>
-<h2 id="Block的基本使用">Block的基本使用</h2>
-<figure class="highlight objc"><table><tr><td class="code"><pre><span class="line"><span class="comment">// 定义一个Block</span></span><br><span class="line"><span class="type">void</span>(^WWBlock)(<span class="type">void</span>) = ^&#123;</span><br><span class="line">    <span class="built_in">NSLog</span>(<span class="string">@&quot;This is a block...&quot;</span>);</span><br><span class="line">&#125;;</span><br><span class="line">        </span><br><span class="line"><span class="comment">// 调用Block</span></span><br><span class="line">WWBlock();</span><br></pre></td></tr></table></figure>
-<p>以上是最简单的一个Block，调用<code>Block()</code>会打印：<code>This is a block...</code>。</p>

-<p>相信这种类似的Block大家在日常项目中会看到很多很多，我们这里就不再一一列举了。</p>
-<h2 id="Block的底层数据结构">Block的底层数据结构</h2>
-<figure class="highlight objc"><table><tr><td class="code"><pre><span class="line"><span class="comment">// 定义一个Block</span></span><br><span class="line"><span class="type">void</span>(^WWBlock)(<span class="type">void</span>) = ^&#123;</span><br><span class="line">    <span class="built_in">NSLog</span>(<span class="string">@&quot;This is a block...&quot;</span>);</span><br><span class="line">&#125;;</span><br><span class="line">        </span><br><span class="line"><span class="comment">// 调用Block</span></span><br><span class="line">WWBlock();</span><br></pre></td></tr></table></figure>
-<p>我们来看一下上面最简单的Block的底层C++结构是什么样的，使用命令<code>xcrun -sdk iphoneos clang -arch arm64 -rewrite-objc main.m -o main.cpp</code>转为C++代码如下：</p>
-<figure class="highlight c++"><table><tr><td class="code"><pre><span class="line"><span class="function"><span class="type">int</span> <span class="title">main</span><span class="params">(<span class="type">int</span> argc, <span class="type">const</span> <span class="type">char</span> * argv[])</span> </span>&#123;</span><br><span class="line">    <span class="comment">/* @autoreleasepool */</span> &#123; __AtAutoreleasePool __autoreleasepool; </span><br><span class="line">        <span class="comment">// 定义Block</span></span><br><span class="line">        <span class="built_in">void</span>(*WWBlock)(<span class="type">void</span>) = ((<span class="built_in">void</span> (*)())&amp;__main_block_impl_0((<span class="type">void</span> *)__main_block_func_0, &amp;__main_block_desc_0_DATA));</span><br><span class="line">                            </span><br><span class="line">        <span class="comment">// 调用Block               </span></span><br><span class="line">        ((<span class="built_in">void</span> (*)(__block_impl *))((__block_impl *)WWBlock)-&gt;FuncPtr)((__block_impl *)WWBlock);</span><br><span class="line">    &#125;</span><br><span class="line">    <span class="keyword">return</span> <span class="number">0</span>;</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>
-<p>把相应的强制转换给去掉能够帮助我们更清晰的理解Block的结构，去掉一些强制转换之后如下：</p>
-<figure class="highlight c++"><table><tr><td class="code"><pre><span class="line"><span class="comment">// 定义Block</span></span><br><span class="line"><span class="built_in">void</span>(*WWBlock)(<span class="type">void</span>) = &amp;__main_block_impl_0(__main_block_func_0, &amp;__main_block_desc_0_DATA));</span><br><span class="line"><span class="comment">// 调用Block      </span></span><br><span class="line">WWBlock-&gt;<span class="built_in">FuncPtr</span>(WWBlock);</span><br></pre></td></tr></table></figure>
-<p>可以看到跟Block相关的有：<code>__main_block_impl_0</code>、<code>__main_block_func_0</code>、<code>__main_block_dec_0_DATA</code>这几个类，在生成的C++文件里面找到相关的结构如下：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202212/1206/1.png" alt="1"></p>
-<p>从上面的图里面我们可以看到，Block的结构里面也有一个<code>isa</code>指针，所以Block的本质其实也是一个【<strong>OC对象</strong>】，是一个封装了函数调用及其调用环境的OC对象。</p>
-<p>对应关系如下图所示：</p>
-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202212/1206/2.png" alt="2"></p>
-<p>在调用的时候<code>WWBlock-&gt;FuncPtr(WWBlock)</code>，相当于是拿到<code>WWBlock</code>结构里面的函数指针<code>FuncPtr</code>去调用对应的方法，这个函数指针里面其实存放的就是Block代码块的地址。</p>
-<h2 id="Block对变量的捕获">Block对变量的捕获</h2>
-<p>为什么Block会对变量进行捕获？</p>
-<p>因为在Block里面可能需要访问Block外部变量的值，所以需要捕获（capture）变量保证我们能正确访问到变量。</p>
-<p>我们现在分别来分析【auto变量】、【static变量】、【全局变量】三种不同的变量，Block对其捕获是不是也不一样呢？</p>
-<h3 id="auto变量">auto变量</h3>

-<p>全局变量在任何时候任何地方都是可以访问到的，因此不需要捕获可以直接访问。</p>
-<p>局部变量因为作用域的问题需要被捕获，保证Block内部能够正确访问到该变量。</p>

+    <content><![CDATA[<h2 id="写在前面-11">写在前面</h2>
+<p>本文主要是记录一下如何越狱，博主这里指的是不完美越狱，博主这里越狱的手机是：iPhone5s  iOS12.5.6。</p>
+<p>首先，你需要有：iPhone手机、Mac电脑，保证Mac和手机上都有<a href="https://www.i4.cn/">爱思助手</a>。</p>
+<h2 id="越狱的简单介绍">越狱的简单介绍</h2>
+<h3 id="什么是越狱？">什么是越狱？</h3>
+<p>越狱：iOS jailbreak，利用iOS系统的漏洞获取iOS系统的最高权限，解开之前的各种限制。</p>
+<div class="note red no-icon flat"><p><strong>越狱的优点</strong>：</p>
+<p>1、可以打造个性化、与众不同的iPhone</p>
+<p>2、可以修改APP的一些默认行为</p>
+<p>3、可以自由安装非App Store来源的App</p>
+<p>4、灵活管理文件系统，让iPhone可以像U盘那么灵活</p>
+<p>5、给开发者提供了逆向功能的环境</p>
+<p><strong>越狱的缺点</strong>：</p>
+<p>1、越狱的手机不予保修</p>
+<p>2、比较耗电，越狱之后的手机会常驻一些进程，耗电速度约提升10%</p>
+<p>3、不再受iOS系统默认的安全保护，容易被恶意软件攻击，个人隐私有被窃取的风险</p>
+<p>4、如果安装了不稳定的插件，容易让系统不稳定、变慢或者出现“白苹果”现象</p>
 </div>

-<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202212/1206/10.png" alt="10"></p>
-<p>程序区域（代码段）：存放的就是我们写的一些代码。</p>
-<p>数据区域：一般是存放一些全局变量。</p>
-<p>堆：动态分配内存，自己管理内存。</p>
-<p>栈：系统自动分配内存，不需要自己管理内存。</p>
-<h3 id="Block类型总结">Block类型总结</h3>
-<div class="note blue no-icon flat"><p>1、只要没有访问auto变量的Block都是<code>__NSGlobalBlock__</code>类型的。</p>
-<p>2、访问了auto变量的Block是<code>__NSStackBlock__</code>类型的，因为我们是在ARC环境下，会自动进行copy操作，所以是<code>__NSMallocBlock__</code>类型的。</p>
-<p>3、<code>__NSGlobalBlock__</code>类型的Block调用了copy还是<code>__NSGlobalBlock__</code>类型。</p>
+<h3 id="完美越狱和不完美越狱">完美越狱和不完美越狱</h3>
+<p>完美越狱：手机在越狱之后可以正常关机和重启。</p>
+<p>不完美越狱：手机不能关机或重启，关机之后可能会出现越狱软件<code>Cydia</code>等无法打开需要重新越狱，严重甚至出现“白苹果”现象。</p>
+<h3 id="Cydia">Cydia</h3>
+<p>Cydia：可以理解为是越狱之后的&quot;App store&quot;，可以在Cydia里面安装一些第三方软件、补丁、插件等。</p>
+<div class="note red no-icon flat"><p><strong>Cydia安装软件的步骤</strong>：</p>
+<p>1、添加软件源（不同的软件软件源可能不一样）（Cydia - 软件源 - 编辑 - 添加 - 输入软件源地址）</p>
+<p>2、进入软件源 - 找到对应的软件开始下载</p>
 </div>
-<h3 id="Block的copy操作">Block的copy操作</h3>
-<p>在ARC环境下，编译器会根据情况自动将栈上的Block复制到堆上，比如以下情况：</p>
-<ul>
-<li>block作为函数返回值</li>
-<li>将block赋值给<code>__strong</code>指针时</li>
-<li>block作为Cocoa API中方法名含有usingBlock的方法参数时</li>
-<li>block作为GCD API的方法参数时</li>
-</ul>
-<div class="note orange no-icon flat"><p><strong>注意</strong>：MRC下Block使用copy关键字修饰，ARC下Block使用strong或copy都可以，建议使用copy，与MRC下保持一致。</p>
+<p>有的插件安装完成之后会要求重启SpringBoard，SpringBoard可以理解为iOS的桌面。</p>
+<h2 id="如何越狱">如何越狱</h2>
+<p>用数据线连接上手机和电脑，打开【爱思助手】- 工具箱 - 一键越狱：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/1.png" alt="1"></p>
+<p>会显示当前手机系统、型号、是否越狱等信息：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/2.png" alt="2"></p>
+<p>博主这里选择Checkra1n进行越狱，出现如下界面：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/3.png" alt="3"></p>
+<p>点击Start，按照如下操作开始下载越狱软件CheckRa1n：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/4.png" alt="4"></p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/5.png" alt="5"></p>
+<p>安装完Checkra1n之后，手机上会有一个checkra1n的软件，打开它开始安装Cydia软件：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/6.png" alt="6"></p>
+<p>安装完Cydia之后，手机桌面会多一个软件如下：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/7.png" alt="7"></p>
+<p>此时连接爱思助手，会发现顶部关于手机的信息会发生变化：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/8.png" alt="8"></p>
+<p>会看到上面提示我们去安装AFC2和AppSync两个插件，这两个插件具体有何用处如下：</p>
+<div class="note red no-icon flat"><p>AFC2：可以保证能够访问整个iOS的文件系统。</p>
+<p>AppSync：保证绕过验证随意安装、运行破解的ipa包。</p>
 </div>
-<h2 id="写在最后-6">写在最后</h2>
-<p>关于Block底层原理的第一篇我们就分享到这里，如有错误请多多指教。</p>
+<p>点击安装AFC2会提示我们如何安装，大家按照自己手机的系统来安装，Cydia - 搜索Apple File… - 安装：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/9.png" alt="9"></p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/10.png" alt="10"></p>
+<p>安装完成之后，点击重启SpringBoard即可。</p>
+<p>此时连接Mac和手机，爱思助手顶部信息如下：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/11.png" alt="11"></p>
+<p>这时我们如果直接点击【安装AppSync】可能会报如下错误：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/12.png" alt="12"></p>
+<p>不用理会，直接在Cydia - 添加软件源：<a href="http://cydia.angelxwind.net">cydia.angelxwind.net</a>，如下图所示：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/13.png" alt="13"></p>
+<p>选择我们刚添加的源 - 插件 - 搜索AppSync - 安装：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/14.png" alt="14"></p>
+<p>安装完成之后同样需要重启SpringBoard，在Cydia - 已安装 里面可以看到我们刚安装的两个插件：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/15.png" alt="15"></p>
+<p>两个都安装成功之后，我们会看到爱思助手顶部信息发生变化，告诉我们该设备已越狱：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202211/1129/16.png" alt="16"></p>

+<p>我们来看一下上面最简单的Block的底层C++结构是什么样的，使用命令<code>xcrun -sdk iphoneos clang -arch arm64 -rewrite-objc main.m -o main.cpp</code>转为C++代码如下：</p>
+<figure class="highlight c++"><table><tr><td class="code"><pre><span class="line"><span class="function"><span class="type">int</span> <span class="title">main</span><span class="params">(<span class="type">int</span> argc, <span class="type">const</span> <span class="type">char</span> * argv[])</span> </span>&#123;</span><br><span class="line">    <span class="comment">/* @autoreleasepool */</span> &#123; __AtAutoreleasePool __autoreleasepool; </span><br><span class="line">        <span class="comment">// 定义Block</span></span><br><span class="line">        <span class="built_in">void</span>(*WWBlock)(<span class="type">void</span>) = ((<span class="built_in">void</span> (*)())&amp;__main_block_impl_0((<span class="type">void</span> *)__main_block_func_0, &amp;__main_block_desc_0_DATA));</span><br><span class="line">                            </span><br><span class="line">        <span class="comment">// 调用Block               </span></span><br><span class="line">        ((<span class="built_in">void</span> (*)(__block_impl *))((__block_impl *)WWBlock)-&gt;FuncPtr)((__block_impl *)WWBlock);</span><br><span class="line">    &#125;</span><br><span class="line">    <span class="keyword">return</span> <span class="number">0</span>;</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>
+<p>把相应的强制转换给去掉能够帮助我们更清晰的理解Block的结构，去掉一些强制转换之后如下：</p>
+<figure class="highlight c++"><table><tr><td class="code"><pre><span class="line"><span class="comment">// 定义Block</span></span><br><span class="line"><span class="built_in">void</span>(*WWBlock)(<span class="type">void</span>) = &amp;__main_block_impl_0(__main_block_func_0, &amp;__main_block_desc_0_DATA));</span><br><span class="line"><span class="comment">// 调用Block      </span></span><br><span class="line">WWBlock-&gt;<span class="built_in">FuncPtr</span>(WWBlock);</span><br></pre></td></tr></table></figure>
+<p>可以看到跟Block相关的有：<code>__main_block_impl_0</code>、<code>__main_block_func_0</code>、<code>__main_block_dec_0_DATA</code>这几个类，在生成的C++文件里面找到相关的结构如下：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202212/1206/1.png" alt="1"></p>
+<p>从上面的图里面我们可以看到，Block的结构里面也有一个<code>isa</code>指针，所以Block的本质其实也是一个【<strong>OC对象</strong>】，是一个封装了函数调用及其调用环境的OC对象。</p>
+<p>对应关系如下图所示：</p>
+<p><img src="https://sunny-blog.oss-cn-beijing.aliyuncs.com/202212/1206/2.png" alt="2"></p>
+<p>在调用的时候<code>WWBlock-&gt;FuncPtr(WWBlock)</code>，相当于是拿到<code>WWBlock</code>结构里面的函数指针<code>FuncPtr</code>去调用对应的方法，这个函数指针里面其实存放的就是Block代码块的地址。</p>
+<h2 id="Block对变量的捕获">Block对变量的捕获</h2>
+<p>为什么Block会对变量进行捕获？</p>
+<p>因为在Block里面可能需要访问Block外部变量的值，所以需要捕获（capture）变量保证我们能正确访问到变量。</p>
+<p>我们现在分别来分析【auto变量】、【static变量】、【全局变量】三种不同的变量，Block对其捕获是不是也不一样呢？</p>

+<p>对照上面的底层数据结构发现：多了两个函数<code>__main_block_copy_0</code>和<code>__main_block_dispose_0</code>。</p>
+<p>当Block被拷贝到堆上时，会调用Block内部的copy函数<code>__main_block_copy_0</code>，函数里面调用<code>_Block_object_assign</code>，在<code>_Block_object_assign</code>里面根据auto变量的修饰符做出相应的操作：强引用或弱引用。</p>
+<p>当Block从对上移除时，会调用Block内部的dispose函数<code>__main_block_dispose_0</code>，函数里面调用<code>_Block_object_dispose</code>，<code>_Block_object_dispose</code>去对引用的auto变量进行一次release操作。</p>
