Setting UIApplication statusBarHidden to YES does not work in iOS 7

Question

I've been using

[UIApplication sharedApplication].statusBarHidden = YES; 

to hide the status bar when users enter specific UIViewControllers in iOS 6 and it worked great. In iOS 7 however it still shows a translucent overlay.

Answer 1

EDITED:::

that is new updated answer :
Do in plist file

"View controller-based status bar appearance" to NO and write code

     [UIApplication sharedApplication].statusBarHidden = YES; 

in appdelegate
