iOS 6 - How to run custom code when orientation changes

Question

I\'m creating a game that allows the device to be in either landscape-left or landscape-right orientation, and the player can change the orientation while it\'s paused. Whe

Answer 1

Listen for device orientation changes:

[[NSNotificationCenter defaultCenter] 
       addObserver:self
          selector:@selector(deviceOrientationDidChangeNotification:) 
              name:UIDeviceOrientationDidChangeNotification 
            object:nil];

When notified, get the device orientation from UIDevice:

- (void)deviceOrientationDidChangeNotification:(NSNotification*)note
{
    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
    switch (orientation)
    {
        // etc... 
    }
}
