Unable to recieve notification in IOS xamarin form - ios

Question

I have developed app for ios and android in xamarin form cross platform. The problem I am facing in notification is that i can receive notification in android and its working absolutely fine, even I can open specific page from notification data, but in IOS I am not able to receieve notification. Here is my code from where I am sending notification
public async void NewTaskNotification(string user_token, string titlee, string bodyy, string openpage, long? mrno, DateTime? appointmentdate)
{
i++;
WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
tRequest.ContentType = "application/json";
var objNotification = new
{
to = user_token,
data = new
{
title = titlee,
body = bodyy,
priority = "high",
id = i,
icon = "ic_stat_ic_stat_ic_notification",
color = "#2F3C51",
Background = "#2F3C51",
open_page = openpage,
mr_no = mrno,
appointmentDate = appointmentdate,
},
};
string jsonNotificationFormat = Newtonsoft.Json.JsonConvert.SerializeObject(objNotification);
Byte[] byteArray = Encoding.UTF8.GetBytes(jsonNotificationFormat);
tRequest.Headers.Add(string.Format("Authorization: key={0}", "AAAAoQ445fk:APA91bHagr12v6bGUqE2d8soHCMXwo4rD6wyM_LFp6yD9b968J3SQQ9u8T5rsFBtsPzL-ct_cCjad_YPpEjaw5tq_OqR_asB5-zgKqyQfhV2djFxAAbK7PBPCZHMI2Y6KmNN8R-MItOA"));
tRequest.Headers.Add(string.Format("Sender: id={0}", "691728344569"));
tRequest.ContentLength = byteArray.Length;
tRequest.ContentType = "application/json";
using (Stream dataStream = tRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse tResponse = tRequest.GetResponse())
{
using (Stream dataStreamResponse = tResponse.GetResponseStream())
{
using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String responseFromFirebaseServer = tReader.ReadToEnd();
FCMResponse response = Newtonsoft.Json.JsonConvert.DeserializeObject<FCMResponse>(responseFromFirebaseServer);
if (response.success == 1)
{
Console.WriteLine("succeeded");
}
else if (response.failure == 1)
{
Console.WriteLine("failed");
}
}
}
}
}
}
with this code i am able to recieve notification and even open specific page but only with android, its not working with ios, but when i try to send notification to IOS from firebase console, its working fine.
Here is my appdelegate.cs
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{
public override bool FinishedLaunching(UIApplication uiApplication, NSDictionary launchOptions)
{
Rg.Plugins.Popup.Popup.Init();
CachedImageRenderer.Init();
global::Xamarin.Forms.Forms.Init();
LoadApplication(new App());
FirebasePushNotificationManager.Initialize(launchOptions, true);
FirebasePushNotificationManager.CurrentNotificationPresentationOption = UNNotificationPresentationOptions.Alert | UNNotificationPresentationOptions.Badge;
UNUserNotificationCenter.Current.Delegate = new UserNotificationCenterDelegate();
return base.FinishedLaunching(uiApplication, launchOptions);
}
public class UserNotificationCenterDelegate : UNUserNotificationCenterDelegate
{
public UserNotificationCenterDelegate()
{
}
public override void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, Action<UNNotificationPresentationOptions> completionHandler)
{
// Do something with the notification
Console.WriteLine("Active Notification: {0}", notification);
// Tell system to display the notification anyway or use
// `None` to say we have handled the display locally.
completionHandler(UNNotificationPresentationOptions.Alert);
}
}
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
FirebasePushNotificationManager.DidRegisterRemoteNotifications(deviceToken);
}
public override void FailedToRegisterForRemoteNotifications(UIApplication application, NSError error)
{
FirebasePushNotificationManager.RemoteNotificationRegistrationFailed(error);
}
public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler)
{
FirebasePushNotificationManager.DidReceiveMessage(userInfo);
// Do your magic to handle the notification data
System.Console.WriteLine(userInfo);
completionHandler(UIBackgroundFetchResult.NewData);
}
}
I need to know where I am doing wrong for IOS
