我不小心编辑了 UIDevice.h 并继续构建我的项目,但收到以下错误:
致命错误:文件'/Applications/Developer/Xcode5-DP4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIDevice. h' 已被修改,因为预编译头 '/Users/MyName/Library/Developer/Xcode/DerivedData/ModuleCache/1EK79MZFJ723Q/UIKit.pcm' 被构建
我进入 UIDevice.h 并撤消了我所做的更改,但此错误仍然存在。我该如何解决?
