iOS8 + UIDeviceOrientationDidChangeNotification not getting called

Question

In my working application (iOS 7.0.1), UIDeviceOrientationDidChangeNotification is called.

Now when i run this application in iOS 8.0 UIDeviceOrientationDidChangeNotification is not getting called.

Tried a lot but no luck.

EDIT-1:

I have use below code to add observer for orientation change. Works perfect in iOS 7. No luck for iOS 8.

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

Answer 1

In my case, after lot of searches I found that I'd made a silly mistake, that my device potrait orientation lock is on.

Please confirm the device orientation lock off in the settings.

This may help someone.

Answer 2

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

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

-(void)didRotateDeviceChangeNotification:(NSNotification *)notification
{
    UIInterfaceOrientation newOrientation =  [UIApplication sharedApplication].statusBarOrientation;
    if ((newOrientation == UIInterfaceOrientationLandscapeLeft || newOrientation == UIInterfaceOrientationLandscapeRight))
    {

    }
}

Swift 3:

Add observer to UIDeviceOrientationDidChange in viewDidLoad

        NotificationCenter.default.addObserver(self, selector: #selector(orientationChanged), name: NSNotification.Name.UIDeviceOrientationDidChange, object: nil)

Selector method is like this:

    func orientationChanged(notification: Notification) {

    }

Don't forget to add Remove observer on deinit method

NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIDeviceOrientationDidChange, object: nil)
