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.
OK, here's the trick. You do have to add the key "View controller-based status bar" and set the value to No.
This is counter to what it appears the meaning of this key is, but even if you set the value to No, you can still change the appearance of the status bar, and whether it shows or not in any view controller. So it acts like "Yes" but set it to "No"!
Now I can get the status bar white or dark.
