UIDevice Notifications

UIDevice can post these notifications:

UIDeviceByOrientationDidChangeNotification UIDeviceBatteryStateDidChangeNotification UIDeviceBatteryLevelDidChangeNotification UIDeviceProximityStateDidChangeNotification

Set this up in the App Delegate, application:didFinishLaunchingWithOptions:

UIDevice *device = [UIDevice currentDevice];

[device beginGeneratingDeviceOrientationNotifications];

NSNotificationCenter *center = [NSNotificationCenter defaultCenter];

[center addObserver:self             selector:@selector(orientationChanged:)             name:UIDeviceOrientationDidChangeNotification             object:device];

- (void)orientationChanged:(NSNotification *)n {     NSLog(@"orientationChanged: %d", [[n object] orientation]); }
