Game center login lock in landscape only in i OS 6

Question

When Game center is loaded its default orientation is portrait. In order to lock it in landscape mode, added a category.

@implementation GKMatchmakerViewCo         


        

Answer 1

At last i avoided crash by following the workaround mentioned in Apple's iOS 6 release notes.

Workaround:

1.Apps should provide the delegate method application:supportedIntefaceOrientationsForWindow and ensure that portrait is one of the returned mask values.

- (NSUInteger)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window
{

    return UIInterfaceOrientationMaskAllButUpsideDown;
}

2. When a UIBNavigationController (or a UIViewController) is involved, subclass the UINavigationController/UIViewController and overriding supportedInterfaceOrientations.

 - (NSUInteger)supportedInterfaceOrientations
    {
        return UIInterfaceOrientationMaskLandscape;
    }

And

In buid summary supported orientations selected landscape right and landscape left.

Now game center is working properly without crash.

Answer 2

Have to add 1 little thing. Struggling with that stupid issue about 2 days. If above doesn't help and you have UINavigationController invovled (and you already did subclass it) you need the following (in appDelegate):

[window setRootViewController:navigationController]; // use this
// instead of [self.window addSubview:navigationController.view];
