问题描述
在Xcode 3.2.1中，我遇到了这个问题，它停止以紫色突出显示对象等。例如：
In Xcode 3.2.1 I have this problem where it stops highlighting Objects in purple, and such. For example:
在该示例中，应突出显示NSAutoreleasePool，pool，img，size，width和height，但是，不是。这是一个看起来像的截图。
In that example, NSAutoreleasePool, pool, img, size, width and height should be highlighted, however, they are not. Here is a screenshot of what that looks like.
任何人都知道如何解决这个问题？
Anyone know how to fix this?
编辑：另外，代码意义没有显示正确的选项。
Also, code sense isn't showing correct options.
推荐答案
Xcode对我来说通常都是类似的方式。重新启动xcode通常可以解决问题。此外，有时缺少分号或大括号会使codeSense和突出显示无法按照您的意愿工作。尝试使用Opt-B（构建）来查看是否有任何可能导致此错误的错误。
Xcode is often glitchy for me in similar ways. Restarting xcode often clears up the issue. Also, sometimes a missing semi-colon or curly brace will keep codeSense and highlighting from working as you want it to. Try Opt-B (build) to see if you have any errors that could be causing this.
