Mimic TV App back button in UIKit

Hi

In my application I'm trying to recreate the behaviour of the back button in the Apple TV app on iOS. What I'm looking for is a way to have a material background but also making it possible to animate (with an interruptible animation) the transition when the user scrolls down in a scroll view.

When searching around there seems to be 2 hacks which doesn't solve my problem. Either you add a static image for the back button, which doesn't solve any of the points I mentioned before. The other hack is to stop using the back button in the UINavigationBar and start leveraging the left button instead, which I don't want because you loose the swipe back gesture.

Can you just pinpoint me what API I could use to get a similar look and feel?
