how to add App Tracking Transparency on maui

Question

How can I add App Tracking Transparency (ATT) to maui app on IOS?

I added this code to MainPage.xaml

protected override void OnAppearing()
{
    base.OnAppearing();

    // Prompt the user for tracking authorization
    ATTrackingManager.RequestTrackingAuthorization(async (status) =>
    {
        string message = "";
        // Handle the user's authorization status here
        switch (status)
        {
            case ATTrackingManagerAuthorizationStatus.Authorized:
                message = "Authorized";
                await Application.Current.MainPage.DisplayAlert("Authorization Status", message, "OK");
                break; 

            case ATTrackingManagerAuthorizationStatus.Denied:
                message = "Denied";
                await Application.Current.MainPage.DisplayAlert("Authorization Status", message, "OK");
                break; 

            case ATTrackingManagerAuthorizationStatus.Restricted:
                message = "Restricted";
                await Application.Current.MainPage.DisplayAlert("Authorization Status", message, "OK");
                break; 

            case ATTrackingManagerAuthorizationStatus.NotDetermined:
                message = "NotDetermined";
                await Application.Current.MainPage.DisplayAlert("Authorization Status", message, "OK");
                break; 
        }
    });
}

and this code to info.plist

<key>NSUserTrackingUsageDescription</key>
<string>This app uses data to deliver personalized advertising.</string>

and it still doesn't work. I don't get any error. but the message is not displayed.

Edit: I expected to get message like this

https://support.apple.com/en-in/HT212025

Define "doesn't work". What do you expect it to do and what doesn't it do? Do you get any error messages? Any info at all? — Gerald Versluis, Feb 15 '23 at 14:22
I don't get any error, it simply not showing up in my app (i add edit in my post to show what i need to get) — Matan Fadida, Feb 15 '23 at 14:32
You might want to check the Apple docs. For some of this stuff I think it only shows up in non-debug scenarios. But not sure for this one. — Gerald Versluis, Feb 15 '23 at 15:42

According to this issue which is about Xamarin App Tracking Transparency Dialog does not appear since iOS 15, you can try to put the code into the /Platforms/iOS/AppDelegates.cs. Such as:

public override void OnActivated(UIApplication application)
      {
            base.OnActivated(application);
        ATTrackingManager.RequestTrackingAuthorization(async (status) =>
        {
            string message = "";
            // Handle the user's authorization status here
            switch (status)
            {
                case ATTrackingManagerAuthorizationStatus.Authorized:
                    message = "Authorized";
                    break;

                case ATTrackingManagerAuthorizationStatus.Denied:
                    message = "Denied";
                    break;

                case ATTrackingManagerAuthorizationStatus.Restricted:
                    message = "Restricted";
                    break;

                case ATTrackingManagerAuthorizationStatus.NotDetermined:
                    message = "NotDetermined";
                    break;
            }
        });
    }

I have tested this in my project, and the alert about requesting permission will show up.

As an addition to the info provided above here is how you then check the permission in one of your .cs files:

#if IOS
    using AppTrackingTransparency;
#endif

#if IOS
    ATTrackingManagerAuthorizationStatus status = ATTrackingManager.TrackingAuthorizationStatus;
    trackingOn = (status == ATTrackingManagerAuthorizationStatus.Authorized);
#endif

I have tried several methods, some from the Xamarin documentation, but I still can't get the message to display in MAUI.

@Matan, did you get it to work?
