Please Help, Why Notification not working on iOS

[PugSingha]

I wrote the code following the ".NET MAUI Local Notifications Guide" tutorial. It works fine on Android devices, but on iOS devices, there are no notifications no errors, and I don't know why.

Hi,
While you wait for others to give you a better answer than mine... I had to add some overwrites in AppDelegate.cs file:

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

    [Export("application:didReceiveRemoteNotification:")]
    public void ReceivedRemoteNotification(UIApplication application, NSDictionary notification)

    [Export("application:didFailToRegisterForRemoteNotificationsWithError:")]
    public void FailedToRegisterForRemoteNotifications(UIApplication application, NSError error)

    [Export("application:didReceiveRemoteNotification:fetchCompletionHandler:")]
    public void DidReceiveRemoteNotification(UIApplication application, NSDictionary notification, Action<UIBackgroundFetchResult> completionHandler)

    [Export("application:didFinishLaunchingWithOptions:")]
    public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)

I got all this information on how to implement Notifications with Firebase and Azure... there is a part where they talk about the AppDelegate:

Hi @PugSingha can you please attach a sample project 🙂?

@thudugala This is a sample project.

@PugSingha is the issue fix. You closed the issue?

@thudugala Srrory, The issue has not yet been resolved, but I edited the information because I accidentally included some personal data, and I only added the sample project file. 😓

[PugSingha]

@thudugala What do I need to do to reopen the issue? I'm a newbie. 😓

[thudugala]

I do get the notification

I made a small change.

public partial class TLocalNotifications : ContentPage
{
    public TLocalNotifications()
	{
		InitializeComponent();
    }

    public static async Task RequestNotificationPermission()
    {
        // Check if notifications are enabled
        if (await LocalNotificationCenter.Current.AreNotificationsEnabled() == false)
        {
            // Basic permission request
            await LocalNotificationCenter.Current.RequestNotificationPermission();
        }
    }

    private async void Button_Clicked(object sender, EventArgs e)
    {
        await RequestNotificationPermission();
        await ShowNotification();
    }
 
    public async Task ShowNotification()
    {
        var notification = new NotificationRequest
        {
            Title = "Notifications",
            Description = "Notification Test",
            NotificationId = 1337,
            iOS = new iOSOptions
            {
                HideForegroundAlert = false
            }
        };

        await LocalNotificationCenter.Current.Show(notification);
    }
}

@thudugala I tested it again using your code, but I'm still not getting any notifications. I'm really confused. 😓😓

[PugSingha]

@thudugala No, it not working on simulator.

Try removing AppDelegate.cs changes you did
