如何在Xcode 4中禁用索引？
不久前我将Xcode更新为版本4.这个新版本花了很多时间来索引项目（它非常大）。这就是我想禁用索引的原因。搜索Xcode帮助和互联网没有结果。
Not a long time ago I updated Xcode to version 4. This new version spent a lot of time on indexing the project (it's quite large). That's why I would like to disable indexing. Searching through Xcode help and internet gave no results.
提前谢谢你！
打开终端窗口并粘贴此命令：
Open a terminal window and paste this command:
默认写入com.apple.dt.XCode IDEIndexDisable 1
你会失去一些功能（自动完成，跳转到定义，一些助手将无法正常工作）。但是你将获得ram和cpu。
You'll lose some features (autocomplete, jump to definition, some of the assistants won't work right). But you'll gain back ram and cpu.
对于我的项目，Xcode从使用2 Gigs到几百MB。 （我非常需要编译;））
For my project Xcode went from using 2 Gigs to a few hundred MB. (which I sorely needed to compile with ;))
