iphone - UIStatusBarStyle PreferredStatusBarStyle does not work on iOS 7

Question

In my iPhone application built with Xcode 5 for iOS 7 I set UIViewControllerBasedStatusBarAppearance=YES in info.plist, and in my ViewController I have this code:

-(UIStatusBarStyle) preferredStatusBarStyle
{
    return UIStatusBarStyleLightContent;
}

But the status bar is still black against the black background.

I know its possible to change this app-wide by setting UIViewControllerBasedStatusBarAppearance=NO in info.plist, but I actually need to alter this on a viewController by viewController basis at runtime.

Answer 1

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.
