preferredInterfaceOrientationForPresentation must return a supported interface orientation

Question

This error doesn\'t make sense, as the preferred orientation UIInterfaceOrientationLandscapeRight is returned by the supported orientation

//iOS         


        

Answer 1

supportedInterfaceOrientations is only called, if shouldAutorotate is set to YES

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

The easiest approach for me, is only to set the Info.plist

If you like to support iOS 5 use this code in your view controllers.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
