iOS Push Notification Configuration

[PzVeCo]

I'm trying to configure push notification features for my cross-platform app. Avalonia does not have an implementation of this, but I found a MAUI guide. The problem is this requires overriding of FinishedLaunching on the AppDelegate, which the AvaloniaAppDelegate does not allow.

I am considering forking Avalonia so I can implement this directly in the FinishedLaunching method, but I suspect maintaining a custom fork is the wrong choice.

Alternately, I am attempting to implement the IUNUserNotificationCenterDelegate interface on the AppDelegate but still have no access to the FinishedLaunching to add the RequestAuthorization call.

public partial class AppDelegate : AvaloniaAppDelegate<App>, IUNUserNotificationCenterDelegate

{
    public UNUserNotificationCenterDelegate PushNotificationHandler = new PushNotificationHandler();
    ...

public class PushNotificationHandler : UNUserNotificationCenterDelegate
{
    public PushNotificationHandler()
    {

    }

    public override void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, Action<UNNotificationPresentationOptions> completionHandler)
    {
        base.WillPresentNotification(center, notification, completionHandler);
    }

    public override void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response, Action completionHandler)
    {
        base.DidReceiveNotificationResponse(center, response, completionHandler);
    }

    public override void OpenSettings(UNUserNotificationCenter center, UNNotification? notification)
    {
        base.OpenSettings(center, notification);
    }
}

If anyone has a guide that I may have missed for implementing notification services (iOS and/or Android), or any advice on this, it would be greatly appreciated.

Hi, Avalonia labs has this feature. https://github.com/AvaloniaUI/Avalonia.Labs/tree/main/src/Avalonia.Labs.Notifications

Oh that's awesome, I will check that out!
I don't know if you have any affiliation, but Notifications is not listed on the Avalonia.Labs Avaliable Controls readme.

Thank you!

Unless I'm mistaken, this can only be used for foreground notifications, not for registering for background notifications, correct? I don't see any way of getting the deviceToken.
