Question

You could also use a protocol here. So, create a protocol like so:

@protocol MyProtocol
-(void)doSomethingWithObject:(id)object;
@end

In your class that needs to call your selector, you then have a @property.

@interface MyObject
    @property (strong) id source;
@end

When you need to call @selector(doSomethingWithObject:) in an instance of MyObject, do this:

[self.source doSomethingWithObject:object];
