How to hide the status bar programmatically in iOS 7?

Question

In ios7, how can I hide the statusbar programmatically? I am using XCode 4.6.1 (ios6.1) and I want to implement this in XCode itself.

Answer 1

To hide for a specific ViewController (and then turn back on) when View controller-based status bar appearance set to NO:

-(void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];
}

-(void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];
}
