Remarks

When a UIDynamicItemBehavior is applied to a IUIDynamicItem, it modifies the default values of the properties used by UIKit Dynamics in that IUIDynamicItem.

The AddAngularVelocityForItem(nfloat, IUIDynamicItem) and AddLinearVelocityForItem(CGPoint, IUIDynamicItem) methods allow the application developer to add arbitrary velocities to a IUIDynamicItem.

Constructors
