UIKit is nowhere to be found?
提问by thesublimeobject
I can't find UIKit.framework anywhere: it's nowhere in my /System/Library/Framework and I can't add it via Build Phase because it's not there to select. I have installed and re-installed xcode and it's not showing up. It doesn't seem to be directly downloadable either. Any ideas?
我在任何地方都找不到 UIKit.framework：它在我的 /System/Library/Framework 中无处可寻，我无法通过 Build Phase 添加它，因为它不在那里可供选择。我已经安装并重新安装了 xcode，但它没有显示出来。好像也不能直接下载。有任何想法吗？

If this is indeed meant to be a question for a Mac OS X application instead of an iOS application @Ken Thomases reply is true. If this question is about making an iOS application with Xcode on Mac OS X then it might be possible your project file is a bit broken. I had to deal with this some weeks ago when all of a sudden I could not add an audio framework.
如果这确实是针对 Mac OS X 应用程序而不是 iOS 应用程序的问题，@Ken Thomases 的回答是正确的。如果这个问题是关于在 Mac OS X 上使用 Xcode 制作 iOS 应用程序，那么您的项目文件可能有点损坏。几周前我不得不处理这个问题，突然我无法添加音频框架。

Alternatively you can show the contents of the package of your project file by CTRL-clicking it and selecting Show Package Contents. There are a lot of user based files there, some might be corrupt. Throw these files away and try again. Backup just to be sure.
或者，您可以通过按住 CTRL 键单击它并选择“显示包内容”来显示项目文件的包内容。那里有很多基于用户的文件，有些可能已损坏。扔掉这些文件，然后再试一次。备份只是为了确定。
Your project's settings should look something like this:
您的项目设置应如下所示：
Build phases:
构建阶段：
It's important that you target iOS and that UIKit and Foundation are there
重要的是你的目标是 iOS 并且 UIKit 和 Foundation 在那里
If they're not, try to create a new project
如果不是，请尝试创建一个新项目
