preferredInterfaceOrientationForPresentation must return a supported interface orientation

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

//iOS6

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return (UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft);
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

Error :

Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'preferredInterfaceOrientationForPresentation must return a supported interface orientation!'

Solution 1:

Your code should look like this:

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

Also, make sure in your Info.plist you have set the correct orientations for you app because what you return from supportedInterfaceOrientations is intersected with the Info.plist and if it can't find a common one then you'll get that error.

Solution 2:

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);
}

Solution 3:

Those are the wrong enums for supportedInterfaceOrientations. You need to use UIInterfaceOrientationMaskLandscapeLeft, etc (note the word mask in the middle)

Solution 4:

from the documentation:

-(NSUInteger)supportedInterfaceOrientations {

    return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft; 
}

Note that the correct orientation is "Mask"! Did you try this?
