Method Not Getting Called

I'm working on Stanford's CS193p (Fall 2010) assignment #3. I have the below code in a UIView subclass:

float scale = [self.delegate scaleForGraphView:self];

Breakpoints and NSLogs inside scaleForGraphView are never triggered, but NSLogs and breakpoints at the above line indicate that it is getting executed. Can someone explain why I'm not seeing execution inside the scaleForGraphView method?

Without more code, that is hard to answer, but it looks as if self.delegate is nil.

Put in:

NSLog(@"%@", self.delegate);

I'd be willing to bet that either:

  1. It's the wrong kind of object
  2. It's nil
