Describes the elements that can be affected by the animator. Classes that implement the methods of this interface can be controlled by the MonoTouch.UIKit.UIDynamicAnimator.

iOS 7 introduced UI Dynamics, which provides physics-based animation for UI elements. The overall coordination of UI Dynamics is performed by a MonoTouch.UIKit.UIDynamicAnimator, which holds references to a number of MonoTouch.UIKit.UIDynamicBehaviors, which define behaviors such as gravity, pushing, and collision detection. Each MonoTouch.UIKit.UIDynamicBehavior holds references to some amount of MonoTouch.UIKit.IUIDynamicItems, which represent the objects to which the physics model is applied.

While this class contains the full protocol definition, and allows for users to override the methods manually in subclasses, if you want to create your own items that can be animated by the physics engine, all you have to do is implement the MonoTouch.UIKit.IUIDynamicItem interface in your object.

Two classes that implement MonoTouch.UIKit.IUIDynamicItem are MonoTouch.UIKit.UIView and MonoTouch.UIKit.UICollectionViewLayoutAttributes.
