iOS Yosemite for iOS 8.1上的C代码编译失败

在我的应用程序中尝试使用C代码时，我遇到了一个奇怪的编译错误。错误如下：

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.1.sdk/usr/include/os/activity.h:38:9: error: declaration of 'uint64_t' must be imported from module 'MachO.arch' before it is required
typedef uint64_t os_activity_t;

完成问题的编译器输出：

我怀疑与我的uint64\u t类型发生冲突，但我如何才能消除它？

删除任何与uint64\u t相关的typedef，如果您没有这样做，则包括在内，以查看发生了什么。根据文档，“导入”不受很好的支持，并且充满了bug。我的建议是：将所有“导入”替换为“包含”，并在每个头文件中使用适当的“ifdef”包装器。
