How to conform to a self-made protocol?

Question

I have a class with an delegate property. Anyone who wants to be a delegate must conform to a protocol. I defined everything like this:

#import 

        

Answer 1

The compiler's warning is correct. OtherClass doesn't conform to the protocol because it doesn't declare the required fooBarWithFoo method that the protocol expects.

Have you tried it this way?

#import "MyClass.h"

@interface OtherClass : NSObject  {
    // ivars
}

- (void)fooBarWithFoo:(CGFloat)foo; // <<< missing bit

@end
