Answer 1

prefersStatusBarHidden is available from iOS 7+.

Use this in Your UIViewController class

   var isHidden = true{
        didSet{
            self.setNeedsStatusBarAppearanceUpdate()
        }
    }
    override var prefersStatusBarHidden: Bool {
        return isHidden
    }

If you change the return value for this method, call the setNeedsStatusBarAppearanceUpdate() method. To specify that a child view controller should control preferred status bar hidden/unhidden state, implement the childViewControllerForStatusBarHidden method.
