UIStatusBarStyle PreferredStatusBarStyle does not work on iOS 7

I discovered that if your ViewController is inside a navigationController then the navigationController’s navigationBar.barStyle determines the statusBarStyle.

Setting your navigationBar’s barStyle to UIBarStyleBlackTranslucent will give white status bar text (ie. UIStatusBarStyleLightContent), and UIBarStyleDefault will give black status bar text (ie. UIStatusBarStyleDefault).

Note that this applies even if you totally change the navigationBar’s color via its barTintColor.
