iOS AppDelegate - Overrides for handling remote notifications not available

[mikeparker104]

Description

In Xamarin.Forms, the following UIApplicationDelegate methods could be overridden on FormsApplicationDelegate.

• UIApplicationDelegate.RegisteredForRemoteNotifications
• UIApplicationDelegate.ReceivedRemoteNotification

public virtual void RegisteredForRemoteNotifications (UIKit.UIApplication application, Foundation.NSData deviceToken);
public virtual void ReceivedRemoteNotification (UIKit.UIApplication application, Foundation.NSDictionary userInfo);

These methods aren't exposed in MauiUIApplicationDelegate alongside with other UIApplicationDelegate methods like FinishedLaunching, OpenUrl, and PerformFetch. The methods must be directly exported instead.

As was the case with the more recently added PerformFetch method (#7957 - iOS AppDelegate - Override for PerformFetch is not available), this may also be a candidate for inclusion as part of ConfigureLifecycleEvents.

events.AddiOS(ios => ios.RegisteredForRemoteNotifications(HandleRegisteredForRemoteNotifications));
events.AddiOS(ios => ios.ReceivedRemoteNotification(HandleReceivedRemoteNotification));

Steps to Reproduce

1. Try to override the RegisteredForRemoteNotifications and ReceivedRemoteNotification methods on iOS (AppDelegate)

Did you find any workaround?

Directly export the requisite methods in the AppDelegate class.

[Export("application:didRegisterForRemoteNotificationsWithDeviceToken:")]
public void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)  { ... }

[Export("application:didReceiveRemoteNotification:")]
public void ReceivedRemoteNotification(UIApplication application, NSDictionary userInfo) { ... }

This is now fixed in .NET 9: #23452

The next preview will have this included.

Correct me if I'm wrong, it won't be in 8? 9 is not even released...
