Question

So I have a class called “DrawOnImageViewController”, which does something pretty obvious. In it’s header file, I also have a protocol “DrawOnImageDelegate” defined with a single method: “imageWithDrawingSelected:(UIImage *)image”. This class also obviously has a “delegate” property that conforms to that protocol.

Now I need to subclass this class so I can simply call that delegate method on the delegate in viewWillDisappear. I subclassed the above class and then overrode viewWillDisappear like so:

-(void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [self.delegate imageWithDrawingSelected:self.imageView.image];
}

This method (viewWillDisappear) executes, but my delegate’s delegate method is never called.
I tried calling: [super.delegate imageWithDrawingSelected:super.imageView.image];

But that doesn’t work either….

Please help. Thanks in advance.

This was an oversight of the most obvious and common kind. I failed to set the delegate property. I’ll go hang my head in shame…

It’s presented in a popover controller, for which the delegate was set, but not the content view controller…
