1.如何替换启动页

yarn add react-native-bootsplash

yarn react-native generate-bootsplash path-to-logo-image

可选参数：

• --background-color=[color] 启动页背景色。hex 格式

• --logo-width=[width] 1 倍图 logo 大小（正方形）。默认为 100

• --assets-path=[path] logo 存放在项目目录下的位置

• --flavor=[flavor] 安卓下有效。表示不是main目录的安卓资源文件夹

生成文件示例：

android/app/src/main/res/drawable/bootsplash.xml
android/app/src/main/res/values/colors.xml (creation and edition)
android/app/src/main/res/mipmap-hdpi/bootsplash_logo.png
android/app/src/main/res/mipmap-mdpi/bootsplash_logo.png
android/app/src/main/res/mipmap-xhdpi/bootsplash_logo.png
android/app/src/main/res/mipmap-xxhdpi/bootsplash_logo.png
android/app/src/main/res/mipmap-xxxhdpi/bootsplash_logo.png

# Only if --assets-path was specified
assets/bootsplash_logo.png
assets/bootsplash_logo@1,5x.png
assets/bootsplash_logo@2x.png
assets/bootsplash_logo@3x.png
assets/bootsplash_logo@4x.png

2. 如何替换应用图标

yarn add -D @bam.tech/react-native-make

npx react-native set-icon --path path-to-image

要求：

• path-to-image 指向图片的路径必填
• 图片必须是正方形的
• 图片不能有透明图层，两个平台都不支持
• 图片最大尺寸是 1024 * 1024
• 支持安卓自适应图标
• 图片格式支持.png 和 .jpeg
• 安卓平台下，上面的命令会在 android/app/src/main/res 目录下生成一堆图标文件

3. 如何生成 svg 图标

• 保证你的项目里安装了 react-native-svg 和 react-native-iconfont-cli
• 执行命令 npx iconfont-init 生成配置文件：

此时项目根目录会生成一个 iconfont.json 的文件，内容如下：

  "symbol_url": "直接复制iconfont官网提供的项目链接。请务必看清是.js后缀而不是.css后缀",
  "use_typescript": false,
  "save_dir": "./src/iconfont",
  "trim_icon_prefix": "icon",
  "default_icon_size": 18,
  "local_svgs": "./localSvgs"

• 开始生成 React-Native 标准组件

npx iconfont-rn
// or
yarn svg-init

4.配置外链打开 app 内指定页面以及传参

在 linking.ts 文件中配置相关链接，相关配置文档查看

通过使用 uri-scheme 配置

npx uri-scheme add rntemplate

测试

npx uri-scheme open rntemplate://路径 --ios

xcode

xcrun simctl openurl booted "rntemplate://路径"

adb

adb shell am start -W -a android.intent.action.VIEW -d "rntemplate://路径" [your android package name]

5.配置热更新

热更新使用的是微软家的 codePush 和使用它家的管理平台https://appcenter.ms

• 需要全局安装 codePush-cli

npm install -g code-push-cli

• 注册-登录

code-push register

code-push login

• 创建应用

code-push app add <appName> <platform> react-native

创建成功后，可以到网站地址查看

• 查看应用 Deploymeny Key

code-push deployment list <appName> -k

• 推送热更新文件

code-push release-react <appName> <platform> [options]
