It is possible in Objective-C.<\/p>\n

We’ll start with a simple rotation and see what happens. If you build, you’ll see that we got a nice rotation but it doesn’t look realistic. We need to skew the perspective as well to get the real effect. <\/p>\n

Getting there!<\/strong><\/p>\n
Alright, after a bit of googling, we’ve figured out how to adjust the m34 value of CATransform3D<\/code> to adjust the perspective we’re looking for. Also made the colors right! Build it and you’ll clearly see where we’re going. But we need to adjust the frame to make sure it fills the screen. Then we could add some automated scrolling animation so we don’t have to scroll with our finger.<\/p>\n
