objective-c

I am getting this warning for the line code:

Class myClass = objc_lookUpClass([_className UTF8String]);

#import <Foundation/NSObjCRuntime.h>
#import <objc/objc.h>

And it still don't resolve the problem

Another warning i get on this line is: "Initialization makes pointer from integer without a cast"
