iPhone - allow landscape orientation on just one viewcontroller

Question

I have a navigation-based application in which I would like just one of the viewcontrollers to support landscape orientation. For that viewcontroller (vc1), in shouldAutorot

Answer 1

I have also situation when I need all view controllers in portait mode, but one of them also can rotate to landscape mode. And this view controller has navigation bar.

For this purpose I have created second window, in my case it was camera view controller. And when I need to show camera view controller, I show camera window and hide when I need to push another view controller.

And you also need to add this code to AppDelegate.

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{   
    if (window == self.cameraWindow)
    {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    }

    return UIInterfaceOrientationMaskPortrait;
}
