iOS 使用CocoaPods 集成第三方库，很容易提交一些不需要的代码到仓库，Xcode编译出来的临时文件这些也不需要提交，SourceTree 可以编辑全局忽略文件列表
- 操作步骤
进入 SourceTree 偏好设置 -> Git -> 全局忽略列表点击编辑文件
添加
*~
.DS_Store
*.xcuserstate
*.xcworkspace
xcuserdata
*.lock
Pods
以上内容可以根据需求修改
添加了.gitignore 还需要把缓存清除一下才生效执行
git rm -r --cached .
git add .
git commit -a -m "清除缓存,gitignore起作用"
git push
更全的.gitignore

# We recommend against adding the Pods directory to your .gitignore. However
# you should judge for yourself, the pros and cons are mentioned at:
# [https://guides.cocoapods.org/using/using-cocoapods.html#should-i-ignore-the-pods-directory-in-source-control](https://guides.cocoapods.org/using/using-cocoapods.html#should-i-ignore-the-pods-directory-in-source-control)

# Note: if you ignore the Pods directory, make sure to uncomment
# `pod install` in .travis.yml
#
Pods/
Podfile.lock
