Custom – because the engine is designed to be extensible, you can create your own custom animations.Decay – dynamic animation that brings a movement to a smooth halt.Spring – dynamic animation that creates a nice bouncing effect.In addition to basic animations including Linear, Ease-In, Ease-Out, Ease-In-Ease-Out animations, it supports spring (at the time of its release, spring animation was not supported in iOS), decay and custom animations: Pop is an extensible animation engine for both iOS and OS X.
