Dear Matthias Bauch, this question is not related to the unrecognised selector question. Can you please remove the duplicate mark? — Andrew Slabko, Aug 26 '15 at 14:04

Try Using

if ([self  respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)])
 {
    [self setNeedsStatusBarAppearanceUpdate];
}

if your app supports older version than iOS 7,and you ever need to use something such as setNeedsStatusBarAppearanceUpdate , you can first check if the selector is supported
