ios6 - ADBannerView.h:20:8：将“NSString”重新定义为不同类型的符号

Question

我收到此错误：

 Redefinition of 'NSString' as different kind of symbol

at line:

extern NSString * const ADErrorDomain;

in ADBannerView.h

它曾经可以工作，与切换SDK有关吗？从ios6到ios7？

Answer 1

Issue was in header, look at your header files in your code.

I had an erroneous int which I must have type in my code.
