iOS 6 autorotation in simulator varies from actual iOS 6 device

Question

My app will not autorotate in the iOS 6 GM simulator but it does with the same version of iOS on the device. Could this be a simulator bug? The app is using deprecated autorotation methods, but they are working fine on the device itself which makes me wonder if the simulator APIs are different?

Answer 1

It should still work with the deprecated rotate methods, but you need to add the following to your didFinishLaunchingWithOptions: method:

self.window.rootViewController = yourRootViewController;

This tells the main window what view controller to send the rotate notifications to. This is new with the iOS 6.0 SDK.

Answer 2

This is what I added to get my app working again:

// Tell the system what we support
- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

// Tell the system It should autorotate
- (BOOL) shouldAutorotate {
    return YES;
}

// Tell the system which initial orientation we want to have
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationPortrait;
}
