Delegate not being set

Question

Could someone please help me with the following code:

    - (IBAction)addCellButton: (UIBarButtonItem *)sender
{
    if(!self.imagePopover)
    {
        AlbumPicker *albumPicker = [self.storyboard instantiateViewControllerWithIdentifier:@"MultipleImagePicker"];
        self.imagePopover = [[UIPopoverController alloc] initWithContentViewController:albumPicker];
        albumPicker.delegate = self;
        NSLog(@"%@", albumPicker.delegate);
        [self.imagePopover presentPopoverFromBarButtonItem:sender
                                  permittedArrowDirections:UIPopoverArrowDirectionAny
                                                  animated:YES];
        self.imagePopover.delegate = self;
    }
}

The problem is is that when I check the delegate in my albumPicker.m by printing it, it is set to nil? Am I setting the delegate properly?

It doesn't appear to be nil. I just checked it by printing it's contents. It is not nil. And when I print albumPicker.delegate, it is not nil in the above code — Nate Mann, Aug 10 '12 at 02:12
So what is nil? imagePopover.delegate or albumPicker.delegate? — rdelmar, Aug 10 '12 at 02:50
In what method in the view controller class are you checking the delegate for nil? — deleted_user, Aug 10 '12 at 05:57
Are you using ARC? And can you post the code (and surrounding methods) you use to check the delegate? — Vervious, Aug 10 '12 at 05:58
Really? You said in your first comment that you could print out the contents of albumPicker, so it can't be null. Did you mean albumPicker.delegate logs null? — rdelmar, Aug 10 '12 at 14:54

It seems that you have set delegate in the right way. I think if the delegate is working properly, it is probably due to the property of delegate .I vaguely remember that in Google(or Apple) coding guidelines, delegate's property should be set as assigned instead of retain.

In addition, your question seems to be somehow unclear to me. I think if you want to check if the delegate is working, you'd better set a delegate method and see if the method is called.
