block delegate methods of class in iphone

Question

I am having a problem I am working on a class which is subclass of UITextField. Which will be used in many classes further. But I don't want to let user to use it's delegate methods in any way.

Is there any way to do this ?

Answer 1

Override setDelegate: so that it throws an exception or logs an instruction on what to do. That way your API users will know what's actually going on.

-(void) setDelegate: (id <UITextFieldDelegate>) delegate
{
    NSLog(@"*** Use the blocks API instead of calling %s", __PRETTY_FUNCTION__);
    [self doesNotRecognizeSelector: _cmd];
}
