我使用以下在gitignore.io中生成的.gitignore文件:

### Xcode ###
build/
*.pbxuser
!default.pbxuser
*.mode1v3
!default.mode1v3
*.mode2v3
!default.mode2v3
*.perspectivev3
!default.perspectivev3
xcuserdata
*.xccheckout
*.moved-aside
DerivedData
*.xcuserstate


### Objective-C ###
# Xcode
#
build/
*.pbxuser
!default.pbxuser
*.mode1v3
!default.mode1v3
*.mode2v3
!default.mode2v3
*.perspectivev3
!default.perspectivev3
xcuserdata
*.xccheckout
*.moved-aside
DerivedData
*.hmap
*.ipa
*.xcuserstate

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

对于Xcode 4，我还添加了:

YourProjectName.xcodeproj/xcuserdata/*
YourProjectName.xcodeproj/project.xcworkspace/xcuserdata/*

我补充说:

xcuserstate
xcsettings

并将我的.gitignore文件放在项目的根目录下。

在承诺和推动之后。然后我跑了起来:

git rm --cached UserInterfaceState.xcuserstate WorkspaceSettings.xcsettings

埋藏在下面的文件夹:

<my_project_name>/<my_project_name>.xcodeproj/project.xcworkspace/xcuserdata/<my_user_name>.xcuserdatad/

然后我再次运行git commit和push

最棒的是，

gitignore.io

去选择你的语言，然后它就会给你文件。

以下是GitHub默认用于新Xcode存储库的.gitignore:

https://github.com/github/gitignore/blob/master/Objective-C.gitignore

它可能在任何给定的时间都是合理正确的。

关于“build”目录排除-

如果您将构建文件放在与源文件不同的目录中，就像我所做的那样，您不必担心树中的文件夹。

这也使得共享代码变得更加简单，防止臃肿的备份，甚至当你依赖于其他Xcode项目时(同时要求构建彼此位于相同的目录中)。

你可以从Github gist https://gist.github.com/708713获取最新的拷贝

我当前的。gitignore文件是

# Mac OS X
*.DS_Store

# Xcode
*.pbxuser
*.mode1v3
*.mode2v3
*.perspectivev3
*.xcuserstate
project.xcworkspace/
xcuserdata/

# Generated files
*.o
*.pyc


#Python modules
MANIFEST
dist/
build/

# Backup files
*~.nib
