如何解决…has been modified since the precompiled header… was built 的问题

 

xcode5.1在程序中报错:

File '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UISegmentedControl.h' has been modified since the precompiled header '/Users/rjxyrjxy/Library/Developer/Xcode/DerivedData/ModuleCache/VMUVAS4MFQHZ/UIKit.pcm' was built

 

具体的解决方法：

 

删除/Users/rjxyrjxy/Library/Developer/Xcode/DerivedData/ModuleCache目录下的所有文件

 

但是如何找到路径呢

 

这里我来告诉大家一个简单快捷的方法(Library是隐藏文件，不容易找的)

 

在Finder上点——>前往——>前往文件夹，会自动弹出让你输入路径，例如：/Users/rjxyrjxy/Library/Developer/Xcode/DerivedData/ModuleCache

会自动找到文件的，删除里面的所有文件就OK了，不过呢，还是报错误的话,你还可以这样做 Project——>Clean ,Shift + Command + K
