IUICollectionViewDelegateFlowLayout IUICollectionViewDelegateFlowLayout Interface

Definition

Interface representing the required methods (if any) of the protocol UICollectionViewDelegateFlowLayout.

[Foundation.Protocol(Name="UICollectionViewDelegateFlowLayout", WrapperType=typeof(UIKit.UICollectionViewDelegateFlowLayoutWrapper))]
[ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS, 6, 0, ObjCRuntime.PlatformArchitecture.All, null)]
public interface IUICollectionViewDelegateFlowLayout : IDisposable, UIKit.IUICollectionViewDelegate
type IUICollectionViewDelegateFlowLayout = interface

Remarks

This interface contains the required methods (if any) from the protocol defined by UICollectionViewDelegateFlowLayout.

If developers create classes that implement this interface, the implementation methods will automatically be exported to Objective-C with the matching signature from the method defined in the UICollectionViewDelegateFlowLayout protocol.

Optional methods (if any) are provided by the UICollectionViewDelegateFlowLayout_Extensions class as extension methods to the interface, allowing developers to invoke any optional methods on the protocol.

Properties

Handle Handle

Handle (pointer) to the unmanaged object representation.

(Inherited from INativeObject)
