Xcode 自带git 使用，忽略用户数据

终端命令:

1.git rm --cached

2.git commit -m "Removed file that shouldn't be tracked"

3.git push

或者以下面所示：

$ git rm --cached iLedger.xcodeproj/project.xcworkspace/xcuserdata/Alex.xcuserdatad/UserInterfaceState.xcuserstate
$ git commit -m "Removed the stupid strange file that shouldn't be tracked"
$ git push
