iOS Development-63 "Unknown type name" CGRect ", Did you mean" Rect "solution

The children's shoes, almost all because of the Xcode6 of the problem.

Cause: Before Xcode6, the file system created automatically imports the Foundation.h and UIKit.h files for the user, but the latest Xcode6 only imports the Foundation.h file for the user, missing one.

So, the solution is: You can import it in the header file section:

#import <UIKit/UIKit.h>

This problem, Google a bit, found a lot.
