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

[Foundation.Protocol(IsInformal=true, Name="UICollectionViewSource", WrapperType=typeof(UIKit.UICollectionViewSourceWrapper))]
[ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS, 6, 0, ObjCRuntime.PlatformArchitecture.All, null)]
public interface IUICollectionViewSource : IDisposable, UIKit.IUICollectionViewDataSource, UIKit.IUICollectionViewDelegate

type IUICollectionViewSource = interface
    interface INativeObject
    interface IDisposable

Derived: UIKit.UICollectionViewController

Remarks

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

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 UICollectionViewSource protocol.

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

Properties

Handle

Handle (pointer) to the unmanaged object representation.
