Overview
Animator objects used in interruptible view controller transitions adopt the UIView protocol to modify in-flight transition animations. This protocol also conforms to the UIView protocol, which specifies methods for starting and stopping animations and for updating their state.
The UIView class adopts this protocol and implements all of its methods. You can adopt this protocol in your own classes to implement custom animator objects. When adopting this protocol, it is recommended that you implement all of the methods.
