Question

I previously made a button and from the storyboard, dragged it to the .h file, and set it like this:

@property (weak, nonatomic) IBOutlet UIButton *deleteComment;

then I realized I needed an action button and erased the code for this button. Now when I try to go to this screen, I get this exception:

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<TopicEditController 0xa027ac0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key edit.'
*** First throw call stack:

and the system points to this spot:

int main(int argc, char *argv[])
{
    @autoreleasepool 
    {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

Could someone please advise me how to stop this from happening?

Thanks!

Your button still is linked to the outlet you deleted. Go into Interface Builder an selet your button. Open the inspector on the right side and delete the outlet connection.
