IUIPickerViewDelegate Interface


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

[Foundation.Protocol(Name="UIPickerViewDelegate", WrapperType=typeof(UIKit.UIPickerViewDelegateWrapper))]
[ObjCRuntime.Unavailable(ObjCRuntime.PlatformName.TvOS, ObjCRuntime.PlatformArchitecture.All, null)]
public interface IUIPickerViewDelegate : IDisposable, ObjCRuntime.INativeObject
type IUIPickerViewDelegate = interface
    interface INativeObject
    interface IDisposable


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

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 UIPickerViewDelegate protocol.

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



Handle (pointer) to the unmanaged object representation.

(Inherited from INativeObject)
