Question

I need to be notified about modal view controller presentation, I know that I can do using NSNotificationCenter posting and observing my custom notifications, but I’d like to know if these kind of notification already exist.
Thanks,
Andrea

Answer 1

I’ve found a solution. I’ve just create an abstract class that overrides the methods for presenting a modal view, like that:

- (void) presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated{
    [[NSNotificationCenter defaultCenter] postNotificationName:PresentingModal object:self];
    [super presentModalViewController:modalViewController animated: animated];
}

Of course all my view controllers inherit from it.
Hope this helps.
