No orientation-related notifications are being fired. Why?

I want to be notified when the orientation of the device changes. I've setup a test method that's suppose to receive the notification. I'm trying several different observers to achieve that, and none of them are working. Why isn't testMethod being fired?

- (void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    // register for orientation change notification

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

    [[NSNotificationCenter defaultCenter] addObserver: self
                                         selector: @selector(testMethod)
                                             name: UIApplicationWillChangeStatusBarOrientationNotification
                                           object: nil];
    [[NSNotificationCenter defaultCenter] addObserver: self
                                         selector: @selector(testMethod)
                                             name: UIApplicationDidChangeStatusBarOrientationNotification
                                           object: nil];
}

- (void)testMethod
{
    NSLog(@"phone was rotated");
}

I accidentally had the rotation lock engaged on my phone. Always test on more than one phone!

You need to use the Orientation notification, which is UIDeviceOrientationDidChangeNotification. Do not put it inside the @"UIDeviceOrientationDidChangeNotification" because you dont know the actual content of the constant which is UIDeviceOrientationDidChangeNotification. It appears you are using a view controller. You should use willRotateToInterfaceOrientation:duration: and didRotateFromInterfaceOrientation:
