The document discusses iOS animation and the UIView class. It provides examples of using UIView methods like beginAnimations and commitAnimations to animate view property changes like center, bounds, transform, backgroundColor and alpha. It also demonstrates how to set animation duration, delay, curve and define animation completion callbacks using delegation. The document compares iOS animation to Android and mentions additional iOS animation topics like loops and the UIKit framework.
