UIDynamicItemBehavior Class

Definition

Specifies physics properties for IUIDynamicItems. Also allows custom velocities to be added to items.

[Foundation.Register("UIDynamicItemBehavior", true)]
[ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS, 7, 0, ObjCRuntime.PlatformArchitecture.All, null)]
public class UIDynamicItemBehavior : UIKit.UIDynamicBehavior
type UIDynamicItemBehavior = class
    inherit UIDynamicBehavior

UIDynamicItemBehavior
Attributes

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.
