Hide navigation bar on scroll

Question

I wonder if its OK by iOS Human Interface Guidelines to style a UIView so it looks and acts like a navbar.

My problem is that I want to hide my current navbar once the user scrolls. I have tried both self.navigationController?.setNavigationBarHidden(true, animated: true) and navigationController?.hidesBarsOnSwipe = true but the animation looks odd, once the navigation bar gets hidden I still have about 20px space under the status bar: You can look at my other question

So to make things easier, can I just init my view tih the navbar hidden and style my own and add the proper animation?

Yes, that's totally fine. Just make sure it's behavior is not unpredictable for iOS users. — alexburtnik, Oct 21 '16 at 11:28
just create the view which looks like navbar & then perfome hide & show. And hide the original nav bar. — Rutvik Kanbargi, Oct 21 '16 at 11:37

Why is "Swift" part of the question title? This is a framework question. — Léo Natan, Oct 21 '16 at 12:35

Try this out :

extension YourViewController {
   override func prefersStatusBarHidden() -> Bool {
      return barsHidden // Custom property
   }

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

You have to update barsHidden somewhere in the code and call setNeedsStatusBarAppearanceUpdate() method.
