Hi,

I have a question regarding the MoviePlayer sample code provided by apple.
I don't understand how the overlayViewTouch notification works. The NSlog message I added to it does not get sent when I touch the view (not button).

// post the "overlayViewTouch" notification and will send
// the overlayViewTouches: message
- (void)overlayViewTouches:(NSNotification *)notification
{
    NSLog(@"overlay view touched");
    // Handle touches to the overlay view (MyOverlayView) here... 
}

I can, however, get the NSlog notification if I place it in -(void)touchesBegan in "MyOverlayView.m". Which makes me think it is recognizing touches but not sending a notification.

 // Handle any touches to the overlay view
    - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
        UITouch* touch = [touches anyObject];
        if (touch.phase == UITouchPhaseBegan)
        {
            NSLog(@"overlay touched(from touchesBegan")
            // IMPORTANT:
            // Touches to the overlay view are being handled using
            // two different techniques as described here:
            //
            // 1. Touches to the overlay view (not in the button)
            //
            // On touches to the view we will post a notification
            // "overlayViewTouch". MyMovieViewController is registered 
            // as an observer for this notification, and the 
            // overlayViewTouches: method in MyMovieViewController
            // will be called. 
            //
            // 2. Touches to the button 
            //
            // Touches to the button in this same view will 
            // trigger the MyMovieViewController overlayViewButtonPress:
            // action method instead.

            NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
            [nc postNotificationName:OverlayViewTouchNotification object:nil];



  }    
}

Can anyone shed light on what I am missing or doing wrong?

Thank you.
