CodeSnippets

Xcode代码段

目标

• 统一代码风格
• 快速构建代码
• 统一OC和Swift代码

使用

使用YCode工具快速安装，可自定义参数

//如果出现了cmdand cmdand cmdand cmdand cmdand cmdand dquote> 输出，将多条命令拆分执行即可
git clone https://github.com/yangzq007/YCode.git && cd YCode && npm install && npm install -g && cd .. && rm -rf YCode && echo "success"

ycode init
ycode userTag <YourUserTag>

直接使用master分支（注意：FIXME和TODO当中的userTag是YCode，建议修改）

cd ~/Library/Developer/Xcode/UserData/
rm -rf ~/Library/Developer/Xcode/UserData/CodeSnippets
git clone https://github.com/yangzq007/CodeSnippets.git

注：原有自定义代码段将被清空，如果想保留，可clone本仓库，将其中的文件放置到~/Library/Developer/Xcode/UserData/CodeSnippets目录下即可
