Setting UIApplication statusBarHidden to YES does not work in iOS 7

问题

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.

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

回答2:

What worked for me was setting "Status bar is initially hidden" to YES in my app's Info.plist.
