Check if status bar is hidden:

Objective C:

if ([UIApplication sharedApplication].isStatusBarHidden) {
    // do stuff here...
}

Swift:

if UIApplication.shared.isStatusBarHidden {
    // do stuff here...
}

Hide status bar:

override var prefersStatusBarHidden: Bool {
    return true
}

Swift 3

if UIApplication.shared.isStatusBarHidden {
    // Do something
}

To hide the status bar (setStatusBarHidden is deprecated in iOS 9) override in your ViewController:

override var prefersStatusBarHidden: Bool {
    return true
}

You can check the current state by using the statusBarHidden property of [UIApplication sharedApplication]

You can set the current state using – setStatusBarHidden:withAnimation:

See the docs for more awesome stuff.
