iOS: Programmatically creating UIWindow results in wrong position

Question

In iOS 5.1.1, I have found that if I create my UIWindow (I'm tired of IB), and set its frame to [UIScreen mainScreen].bounds, the window shows up under the status bar. However if I do the same thing is iOS 6, it appears in the right spot just below the status bar.

CGRect r = [[UIScreen mainScreen] bounds];
self.window = [[UIWindow alloc] initWithFrame: r];
self.detailViewController = [[DetailViewController alloc] init];
self.window.rootViewController = self.detailViewController;
[self.window addSubview: detailViewController.view];
[self.window makeKeyAndVisible];

If however I insert r.origin.y += 20, to move the window below the status bar in iOS 5.1.1, this does not solve the problem and things only get weirder.

What is the proper way to place a UIWindow in iOS when creating it programmatically? Thanks.

Instead of [[UIScreen mainScreen] bounds] you'll want to use [[UIScreen mainScreen] applicationFrame]. This will be the area of the screen below the status bar (if visible).
