iOS

AppsFlyer enables you to track app uninstalls. To handle notifications it requires to modify your AppDelegate.m. Use didRegisterForRemoteNotificationsWithDeviceToken to register to the uninstall feature.

UnityEngine.iOS.NotificationServices is now deprecated. Please use the "Mobile Notifications" package instead. It is available in the Unity package manager.

Example:

using AppsFlyerSDK;
using Unity.Notifications.iOS;

public class AppsFlyerObjectScript : MonoBehaviour, IAppsFlyerConversionData
{

    void Start()
    {
        AppsFlyer.initSDK("devKey", "appID", this);
        AppsFlyer.startSDK();
#if UNITY_IOS
  
        StartCoroutine(RequestAuthorization());
        Screen.orientation = ScreenOrientation.Portrait;

#endif

    }


#if UNITY_IOS
    IEnumerator RequestAuthorization()
    {
      
        using (var req = new AuthorizationRequest(AuthorizationOption.Alert | AuthorizationOption.Badge, true))
        {

            while (!req.IsFinished)
            {
                yield return null;
            }
             if (req.Granted && req.DeviceToken != "")
             {
                  byte[] tokenBytes = ConvertHexStringToByteArray(req.DeviceToken);
                  AppsFlyer.registerUninstall(tokenBytes);
             }
        }
    }

    private byte[] ConvertHexStringToByteArray(string hexString)
    {

        byte[] data = new byte[hexString.Length / 2];
        for (int index = 0; index < data.Length; index++)
        {
            string byteValue = hexString.Substring(index * 2, 2);
            data[index] = System.Convert.ToByte(byteValue, 16);
        }
        return data;
    }
#endif
}

In the Unity class handling the AppsFlyer code, add the following:

using Firebase.Messaging;
using Firebase.Unity;

Add to the Start() method:

Firebase.Messaging.FirebaseMessaging.TokenReceived += OnTokenReceived;

Add the following method:

    public void OnTokenReceived(object sender, Firebase.Messaging.TokenReceivedEventArgs token)
