Interface orientation in iOS 6.0

Question

How to use the following methods to support interface orientation in iOS 6.0:

shouldAutorotate

supportedInterfaceOrientations

preferredInterfaceOrientationForPresentation

As "shouldAutorotateToInterfaceOrientation" is deprecated in iOS 6.0.

Please provide code snippets to support your answers.

Thanks.

Answer 1

Deprecated method in iOS 5:

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

Replacement in iOS 6 and equivalent of this deprecated iOS 5 method above:

- (BOOL) shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight;
}

Hope this helps.

By the way, your settings on your Xcode project settings now take precedence. Make sure that you set the "Supported interface orientations" array properly in your project's settings. That was the issue for me. Removed the undesired ones and my app worked like it did when I compiled with Xcode 4.4.1
