What should I do about xcuserdata directories with my old username?
提问by Blacklight Shining
(I have a mac running Mountain Lion with Xcode 4.5.2)
（我有一台使用 Xcode 4.5.2 运行 Mountain Lion 的 mac）
I changed my username a while ago, and Xcode has started recreating xcuserdatadirectories with the new username at $path_to_.xcodeproj/xcuserdata/blackl.xcuserdatad. I've been working with it like that since, and I can't remember if anything seemed to have reset after the change, so whatever was in there must not have been too important…
不久前我更改了我的用户名，Xcode 开始xcuserdata使用新用户名重新创建目录$path_to_.xcodeproj/xcuserdata/blackl.xcuserdatad. 从那以后我就一直这样使用它，我不记得在更改后是否有任何东西似乎已经重置，所以那里的任何内容一定不是太重要......
What does Xcode store in xcuserdataand what should I do about the old ones? There are some old projects I haven't opened since the change; I could just rename the directories in those. Newer projects will have two directories (blackl.xcuserdatadand one with the old username); what should I do in those cases?
Xcode 存储xcuserdata什么，我应该如何处理旧的？有一些旧项目改了之后就没有打开了；我可以重命名这些目录。较新的项目将有两个目录（blackl.xcuserdatad一个是旧用户名）；在这些情况下我该怎么办？

You can safely delete the xcuserdata directories. It basically contains personal settings like breakpoints, user interface layout, open files, automatic snapshots configuration and so on.
您可以安全地删除 xcuserdata 目录。它基本上包含个人设置，如断点、用户界面布局、打开的文件、自动快照配置等。
Most people ignore those files in their version control software. I do that too.
大多数人在他们的版本控制软件中忽略这些文件。我也这样做。
BTW: there's another xcuserdata directory inside of $path_to_.xcodeproj/project.xcworkspace.
顺便说一句：.net 中有另一个 xcuserdata 目录$path_to_.xcodeproj/project.xcworkspace。
