In this video, we will learn about animations in iOS, though you can use lightweight UIViewAnimation's but CATransition provides a more control to you over the animation.
CATransition animation, has various properties like type of animation and subtype. You can also specify animation speed in CATransition. It provides more control to the developer as this animation works on layer of the UIView.
We will create demo project, which demonstrate how to use CATransition animation in a shopping cart like user interface.
