XCode 4 存档错误:找到一个或多个 PCH 文件，但它们无效 [英] XCode 4 Archiving Error: one or more PCH files were found, but they were invalid

问题描述

在此处记录一个奇怪的 XCode 4 错误以供将来参考:

Documenting an odd XCode 4 Error here for future reference:

找到了一个或多个 PCH 文件，但它们无效"

"one or more PCH files were found, but they were invalid"

清理并不能解决问题，您需要通过按住 ALT 并从菜单中选择产品来清理构建文件夹.Clean"条目现在将更改为Clean Build Folder"，这将清除错误的 PCH 重复项并无错误地编译.

Cleaning does not fix the issue, you need to clean the Build Folder by holding down ALT and selecting Product from the menu. The "Clean" entry will now have changed to "Clean Build Folder" which will wipe the bad PCH duplicates and compile without errors.
