Question

I have the following code in my UIViewController subclass, however the willAnimateROtationToInterface is never called. Any idea why?

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return YES;
}

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{

}

UPDATE:
The parent’s view controller orientation changes delegate is getting called however not this one. I added this view controller as a subview of the parent’s view controller

The parent view controller is a UINavigationController, so here’s how I am adding the subview:

[self.navController.view addSubview:viewController.view];

It turned out this was an issue with view controller containment, i.e. the UIViewController was being nested inside another custom UIViewController subclass, which was not forwarding the notifications (or using iOS5’s UIViewController containment methods).
