Xcode 从 .pch 编译错误？(iOS)

Xcode compile errors from .pch? (iOS)

提问by stuartloxton

While making changes to an iPhone app I saved and compiled; got the errors below... undid everything and I am now stuck with these errors. I've tried cleaning the build, copying the files out of this folder, tried building on another machine. Nothing I can think of solves it, the change I made was to the .xib file; I removed the IBOutlet because I no longer needed the element.

在对我保存和编译的 iPhone 应用程序进行更改时；得到下面的错误...取消一切，我现在被这些错误困住了。我试过清理构建，从这个文件夹中复制文件，尝试在另一台机器上构建。我想不出什么来解决它，我所做的更改是对 .xib 文件；我删除了 IBOutlet，因为我不再需要该元素。

Does anyone know how I can resolve these issues -> sorry for the long debug output but thought too much information would be better than too little.

有谁知道我如何解决这些问题 -> 对冗长的调试输出感到抱歉，但认为信息太多总比太少好。

I've just encountered the same problem with iOS 4 SDK. After I changed compiler from LLVM compiler 1.5to either LLVM GCC 4.2or GCC 4.2, everything returned OK.

我刚刚在 iOS 4 SDK 上遇到了同样的问题。在我将编译器从LLVM 编译器 1.5更改为LLVM GCC 4.2或GCC 4.2 后，一切都恢复正常。

Is it a Clang bug?

这是一个 Clang 错误吗？

It seems to be a bug in 4.1, so if you haven't updated (yet) to 4.2, add this to your prefix file:

这似乎是 4.1 中的一个错误，所以如果您还没有更新（还）到 4.2，请将其添加到您的前缀文件中：

#if TARGET_IPHONE_SIMULATOR
#define __IPHONE_OS_VERSION_MIN_REQUIRED 040100
#warning "Remove This in SDK 4.2, needed because of a bug in SDK 4.1"
#endif
