Hide the status bar on ios7

1. I tried to check the Hide during application launch option. No.

2. I tried to use a function in ViewController, but it still cannot.

-(BOOL) prefersStatusBarHidden {return YES; // hide as YES and display as NO}

You can find this method later. Mark it!

Add a new row in Info. plist, "View controller-based status bar appearance", and set the key value to NO.

To display the status bar, you can set it through code.

// Display the status bar [[UIApplication sharedApplication] setStatusBarHidden: FALSE];
