How to hide status bar gradually in swift

Question

I have a table view controller. When user scroll the table up, I want to hide iphone status bar(the top one which includes battery, WIFI etc.) gradually. I know how to hide the status bar by implementing prefersStatusBarHidden() method. But it doesn't hide it with the table scrolling up. So I want it to be kind of part of the table. It should be able to move with the table moving.

initially you get scroll direction of UItableview , then set as BOOL value based on direction

func scrollViewDidScroll(scrollView: UIScrollView) {
   if(scrollView.panGestureRecognizer.translationInView(scrollView.superview).y > 0)
{
    print("up")
   UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: .Fade)  //.Slide
}
else
{
    print("down")
    UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: .Fade)  //.Slide
}
}

UIApplication.sharedApplication().setStatusBarHidden is deprecated in iOS9

Choice-2

 crete one global Value for get the current position
var hide:Bool = false

 func scrollViewDidScroll(scrollView: UIScrollView) {
   if(scrollView.panGestureRecognizer.translationInView(scrollView.superview).y > 0)
{
    print("up")
   hide = true

}
else
{
    print("down")
   hide = false

}
  UIView.animateWithDuration(0.5) { () -> Void in
        self.setNeedsStatusBarAppearanceUpdate()
    }
}


override func preferredStatusBarUpdateAnimation() -> UIStatusBarAnimation {
    return UIStatusBarAnimation.Slide
}
override func prefersStatusBarHidden() -> Bool {
    return hide
}

There is no way to move the status bar; it is either visible or hidden. However, you can get around this by replacing the status when the UITableView is about to be scrolled with a UIView containing a screenshot that includes the status bar.

I would start with the UIScrollViewDelegate. Since the UITableViewDelegate is a subclass of the UIScrollViewDelegate, you can, in your view controller, set your UITableView's delegate to self. With this, you can now listen to scrolling movements.

When the UITableView is at the top and the user is scrolling down, I would recommend to take a screenshot of the status bar, add it to a UIView, and move that said view up at the same speed as the UITableView is moving (see the UIScrollViewDelegate documentation for help). Likewise, when scrolling to the top, I would have the view move down to the position of the status bar, then remove the view, and set the status bar visible.

With this method, you have the appearance of the status moving up and down with the table view.

Try This

func scrollViewDidScroll(scrollView: UIScrollView)
{
    UIApplication.sharedApplication().statusBarHidden = true
}

func scrollViewDidEndDecelerating(scrollView: UIScrollView)
{
    UIApplication.sharedApplication().statusBarHidden = false
}

It works but it is not hidden with the table scroll up. – Joey Yi Zhao Mar 09 '16 at 05:57
