提问by Matt Fellows

I've messed up my iPhone project. I ran svn update, having fiddled with the repository months ago. Many changes since, make recovering from an old point nearly impossible.

我搞砸了我的 iPhone 项目。我跑了svn update，几个月前摆弄过存储库。此后发生了许多变化，几乎不可能从旧点恢复。

When I attempt to build the project now I get:

当我现在尝试构建项目时，我得到：

And I have no idea why Event_Prefix.pchis not there to be clanged. (I don't even know what clang is) Any help, suggestions on how to debug, tips on how to fix, greatly appreciated.

而且我不知道为什么Event_Prefix.pch没有叮当声。（我什至不知道什么是叮当声）任何帮助，如何调试的建议，如何修复的提示，非常感谢。

Clang is the compiler. Make sure you have a Event_Prefix.pchfile in your project file.

Clang 是编译器。确保您Event_Prefix.pch的项目文件中有一个文件。

I was having this just on a test build. Seems the test target did not update a naming change.

我只是在测试版本中使用它。似乎测试目标没有更新命名更改。

In my case, my search paths were not recursive.

就我而言，我的搜索路径不是递归的。

I got this error, when renaming the project and also changing the folder names.

我在重命名项目并更改文件夹名称时遇到此错误。

In Xcode you can easily set the new paths by selecting a group/folder reference, open the Utilities sidebar (Menubar: View > Utilities > Show File Inspector) and clicking on the small folder icon in the section "Identity and Type".

在 Xcode 中，您可以通过选择组/文件夹引用轻松设置新路径，打开实用工具侧栏（菜单栏：）View > Utilities > Show File Inspector并单击“身份和类型”部分中的小文件夹图标。

But: the paths are also set somewhere deep in the project configuration. Select your Project, go to "Build Settings", on the left under "TARGETS" choose your App, and correct the paths of:

但是：路径也都在项目配置设置深刻的地方。选择您的项目，转到“构建设置”，在左侧的“目标”下选择您的应用程序，并更正以下路径：

• Packaging > Info.plist File
• Apple LLVM 5.1 - Language > Prefix Header

• 打包 > Info.plist 文件
• Apple LLVM 5.1 - 语言 > 前缀头
