Objective-c – iOS 6 auto rotation issue – supportedInterfaceOrientations return value not respected

autorotateios6ipadiphoneobjective c

I've got an app where I have a UINavigationController subclass as my rootViewController. I've got a UITableViewController that lets the user edit some settings, it should always be in portrait mode. My app also needs to support all other orientations after I push a MoviePlayer component onto the navigation controller.

The UITableViewController subclass has this implementation of supportedInterfaceOrientations:

- (NSUInteger)supportedInterfaceOrientations {
    LLog();
    return UIInterfaceOrientationMaskPortrait;
}

The logging command tells me that this gets actually called.

The problem is that the return value is not respected, i.e. the screen turns to landscape orientation when I turn the device.

What can I do to make the settings view always show in portrait but allow orientation changes for the video viewer?

More information: my UINavigationController subclass doesn't override shouldAutorotate or supportedInterfaceOrientations. I haven't implemented

   - (NSUInteger)application:(UIApplication *)application 

supportedInterfaceOrientationsForWindow:(UIWindow *)window

method in my AppDelegate and I have enabled all orientations in the target summary.

Best Answer

I had issue that some ViewControllers in the navigation stack support all the orientations, some only portrait, but UINavigation controller was returning all app supported orientations, this little hack helped me.

@implementation UINavigationController (iOS6OrientationFix)

-(NSUInteger) supportedInterfaceOrientations {
    return [self.topViewController supportedInterfaceOrientations];
}

@end

IOS 6 rotations: supportedInterfaceOrientations doesn´t work

If your ViewController is a child of a UINavigationController or UITabBarController, then it is the parent that is your problem. You might need to subclass that parent view controller, just overriding those InterfaceOrientation methods as you've shown in your question

EDIT:

Example for portrait only TabBarController

           @interface MyTabBarController : UITabBarController
            {
            }
            @end

            @implementation MyTabBarController

            // put your shouldAutorotateToInterfaceOrientation and other overrides here        
            - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
                return (interfaceOrientation == UIInterfaceOrientationPortrait);
            }

            - (NSUInteger)supportedInterfaceOrientations{ 
                return UIInterfaceOrientationMaskPortrait; 
            } 

        @end

IOS 6: How to restrict some views to portrait and allow others to rotate

I had the same problem and found a solution that works for me. To make it work, it is not sufficient to implement - (NSUInteger)supportedInterfaceOrientations in your UINavigationController. You also need to implement this method in your controller #3, which is the first one to be portrait-only after popping controller #4. So, I have the following code in my UINavigationController:

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    if (self.isLandscapeOK) {
        // for iPhone, you could also return UIInterfaceOrientationMaskAllButUpsideDown
        return UIInterfaceOrientationMaskAll;
    }
    return UIInterfaceOrientationMaskPortrait;
}

In view controller #3, add the following:

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

You don't need to add anything to your view controllers #1, #2, and #4. This works for me, I hope it will help you.
