Xcode从.pch编译错误？ （IOS）

Question

在更改我保存和编辑的iPhone应用程序时;得到了以下错误......解开了一切，我现在陷入了这些错误。我已经尝试清理构建，从这个文件夹复制文件，尝试在另一台机器上构建。我无法想到解决它，我所做的改变是.xib文件;我删除了IBOutlet，因为我不再需要该元素。

有谁知道如何解决这些问题 - ＆gt;对于长调试输出感到遗憾，但是认为太多信息会比太少更好。

Answer 1

我刚刚遇到iOS 4 SDK的同样问题。将编译器从 LLVM编译器1.5 更改为 LLVM GCC 4.2 或 GCC 4.2 后，所有内容都返回OK。

这是一个Clang bug吗？

Answer 2

这似乎是4.1中的一个错误，所以如果你还没有更新到4.2，请将它添加到你的前缀文件中：

#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
