Question

Hi I have an Tab Bar based application. When I click on the third tab,the view which opens up has a tableview ( AggregateMediaViewController ). On didSelect of the rows, I open a video using MPMoviePlayerViewController . I want to set the the orientation of the this video whenever the orientation of the device changes. I created a subclass of UITabbarController called OrientationTabBarController :

@implementation OrientationTabBarControllerViewController
- (BOOL)shouldAutorotate {
    NSLog(@"in shouldAutorotate tabbar is %@", self.viewControllers);

    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

In the appDidFifnishLaunching: [window setRootViewController:tabBarController]; where the tabBarController is a subclass of OrientationTabBarController.

In AggregateMediaViewController, I have the following code:

- (BOOL)shouldAutorotate
{
    NSLog(@"in shouldAutorotate of media");
    return YES;
}

-(NSInteger)supportedInterfaceOrientations {    
    return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPortraitUpsideDown);
}

But when I run the application, orientation does not work :( Please Help

You need to subclass your parent controller and add rotation methods of your UIViewController . In your case it is UITabBarController. And set it as rootViewController in appDelegate:

[self.window setRootViewController:_myTabBarController];
