Keep previous pages in UIPageViewController
问题 So I want to create an interface like the image above (it is a snapshot form the mosaic app). When you turn the page this is the kind of behavior happening. So what is different here is that the cover (the black part) is still visible once you turn the page (the cover is flippable as well, not just a static asset). In a UIViewController when I flip the page it unloads the previous view. So how do I go about implementing this ? Any help or nudge in the right direction will be much appreciated.
