为什么要配置.gitigore

在我们使用git的过程当中，不是任何文件都需要commit到本地或者远程仓库的，比如一些三方库文件。

那么作为一个git新手，很多人不知道如何配置.gitignore文件，本文只是提供一个便捷的例子。你可以直接使用本文提供的代码编辑到你的.gitigore文件中。

简便配置

直接复制下面的内容到你的.gitignore文件即可。注意，这个配置是给iOS开发者使用的。

# Xcode
.DS_Store
*/build/*
*.pbxuser
!default.pbxuser
*.mode1v3
!default.mode1v3
*.mode2v3
!default.mode2v3
*.perspectivev3
!default.perspectivev3
xcuserdata
profile
*.moved-aside
DerivedData
.idea/
*.hmap
*.xccheckout
*.xcworkspace
!default.xcworkspace

#CocoaPods
Pods
!Podfile
!Podfile.lock

到gitignore.io去选择自定义配置

在 gitignore.io 输入你需要配置的语言，会帮助你自动生成一份配置。比如，输入Objective-C和Swift会帮助你生成下面的配置。

# Created by https://www.gitignore.io/api/objective-c,swift

这个配置自动生成了很多注释和一些不太必要的配置，所以直接使用上面提供的简便配置就好。
