A Self-Rotating View Controller

If you have a need to place a view controller directly into a window, without it being a child of that window’s root view controller, then you’ll likely have found that rotation doesn’t happen automatically for you. Which is a serious pain. This class has the answer.

Using AQSelfRotatingViewController

Make your controller class a subclass of AQSelfRotatingViewController. Before adding its -view to your UIWindow, be sure to call -viewWillAppear:, and also call -viewDidAppear: after adding it. Likewise call -viewWillDisappear: and -viewDidDisappear: when removing the view from the window.

That’s it. No, really— that’s it.
