objective c - UIAlertView crashs in iOS 8.3

Question

recently i start receiving crash reports for UIAlertView only by users that use iOS 8.3

Crashlytics reports:

Fatal Exception: UIApplicationInvalidInterfaceOrientation Supported orientations has no common orientation with the application, and [_UIAlertShimPresentingViewController shouldAutorotate] is returning YES

The line where that crash happens is [alertView show] :

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:title
                                                    message:message
                                                   delegate:nil
                                          cancelButtonTitle:cancelButtonTitle
                                          otherButtonTitles:nil];
[alertView show];

that code is in the app for a long time and now it starts crashing. Did anyone experience a similar behaviour and has fixed the problem?

Answer 1

The main thing is :

UIApplicationInvalidInterfaceOrientation Supported orientations has no common orientation with the application

It means you have somewhere implemented

- (NSUInteger)supportedInterfaceOrientations {

    return UIDeviceOrientationPortrait; // or UIInterfaceOrientationPortrait
}

UIInterfaceOrientationPortrait = UIDeviceOrientationPortrait = 0

In that function MUST be returned Mask like:

UIInterfaceOrientationMaskPortrait which is 1
