How to set AViewController (subclass of TabBar and Nav Controller) to portrait only

Question

If I have AViewController which is a subclass of TabBarController and NavigationController, is it possible to set it to portrait? while, the other ViewController can rotate normally. (Portrait and Landscape)

Thank you

Yes it is. You can find the documentation here. You just have to override a few methods and return supported orientations for each view controller, such as supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation methods.

For example, to limit the orientation to portrait you would do

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    return interfaceOrientation == UIInterfaceOrientationPortrait;
}

Edit:

I added the preferredInterfaceOrientationForPresentation method. Try this. This is the exact code i'm using in one of our apps, and it is working for us.
