  1. PORotating view controllers within a hierarchy of Tab Bar Controller -> Navigation Controller -> View Controller
    text
    copied!<p>My app has a view controller hierarchy set up like this:</p> <pre><code>UITabBarController | UINavigationController | | | UIViewController | UINavigationController | UIViewController </code></pre> <p>All of my view controllers that are within this hierarchy override the method:</p> <pre><code>- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation </code></pre> <p>and return <code>YES</code> - therefore the view controller should be able to rotate to any rotation - even upside down.</p> <p>However, within this setup none of the view controllers successfully rotate. I was under the impression that navigation and tab bar controllers would rotate if their view controllers respond to rotating.</p> <p>Why won't my view controllers rotate?</p> <p>The only way I've been able to get them to rotate is by subclassing <code>UINavigationController</code> and overriding it's <code>shouldAutorotate</code> method, but this feels unnecessary to me and I was wondering if there's something I've missed to make this work.</p> <h2>Edit:</h2> <p>According to the User Experience Coding How-to:</p> <blockquote> <p>If you are also using a toolbar, the view controller for each toolbar item must implement the shouldAutorotateToInterfaceOrientation: method and return YES for each of the orientations you wish to support. If you have a navigation controller for a toolbar item, the root view controller of that navigation controller must implement the shouldAutorotateToInterfaceOrientation: method and return YES.</p> </blockquote> <p>It says 'toolbar' - but I think this is a typo and is probably supposed to be 'tab bar'.</p> <p>So it seems that I'm implementing this correctly, yet my controllers still do not auto rotate.</p>
