我正在尝试在我的移动的应用程序中发送远程通知，该应用程序使用Xamarin. Forms构建。我已经在Firebase中进行了所有必要的控制台设置，并上传了google-services.json和googleService-info. plist。通知功能在Xamarin.Forms android上运行良好，但同样的代码在Xamarin forms iOS上不起作用。
我的应用程序xamal.cs：

public partial class App : Application
{
     public App()
     {
            InitializeComponent();
            CrossFirebasePushNotification.Current.OnTokenRefresh += (s, p) => {
                  string token = p.Token;
                  System.Diagnostics.Debug.WriteLine($"TOKEN REFRESHED: {token}");
                  _ = MyService.UpdateUserDeviceToken(token);
            };
     }
     ...
}

这是我的AppDelegate的存储方式：

namespace MyApp.iOS
{
    [Register("AppDelegate")]
    public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
    {
        public override bool FinishedLaunching(UIApplication app, NSDictionary options)
        {
            global::Xamarin.Forms.Forms.Init();
            LoadApplication(new App());
            FirebasePushNotificationManager.Initialize(options, true);
            return base.FinishedLaunching(app, options);
        }

        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);
            completionHandler(UIBackgroundFetchResult.NewData);
        }

        public override void WillEnterForeground(UIApplication uiApplication)
        {
            LocalNotificationCenter.ResetApplicationIconBadgeNumber(uiApplication);
            base.WillEnterForeground(uiApplication);
        }
    }
}

除此之外，我还在Entitlements.plist和Info.plist中启用了推送通知，在后台模式中启用了远程通知，并添加了FirebaseAppDelegateProxyEnabled
但是，它仍然不会在刷新令牌事件上触发。这个东西在Android上运行得非常好，刷新令牌会被触发。我已经参考了这个金块包插件。PushNotification
