Xamarin Android iOS FirebasePushNotification插件不接收消息，但接收令牌

Question

我正在使用xamarin iOS FirebasePushNotificationPlugin进行云消息，但我收到了令牌，但我无法收到任何通知。CrossFirebasePushNotification.Current.OnNotificationReceived甚至不开火。

这是我的应用代表的样子。

using System;
using System.Collections.Generic;
using System.Linq;
using Foundation;
using Plugin.FirebasePushNotification;
using UIKit;
namespace onlinefirebase.iOS
{
// The UIApplicationDelegate for the application. This class is responsible for launching the 
// User Interface of the application, as well as listening (and optionally responding) to 
// application events from iOS.
[Register("AppDelegate")]
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{
//
// This method is invoked when the application has loaded and is ready to run. In this 
// method you should instantiate the window, load the UI into it and then make the window
// visible.
//
// You have 17 seconds to return from this method, or iOS will terminate your application.
//
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
global::Xamarin.Forms.Forms.Init();
LoadApplication(new App());
FirebasePushNotificationManager.Initialize(options, true);
FirebasePushNotificationManager.CurrentNotificationPresentationOption =
UserNotifications.UNNotificationPresentationOptions.Alert |
UserNotifications.UNNotificationPresentationOptions.Badge;
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);
}
// To receive notifications in foregroung on iOS 9 and below.
// To receive notifications in background in any iOS version
public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler)
{
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired 'till the user taps on the notification launching the application.
// If you disable method swizzling, you'll need to call this method. 
// This lets FCM track message delivery and analytics, which is performed
// automatically with method swizzling enabled.
FirebasePushNotificationManager.DidReceiveMessage(userInfo);
// Do your magic to handle the notification data
System.Console.WriteLine(userInfo);
completionHandler(UIBackgroundFetchResult.NewData);
}
}
}

以下是我接收通知的方式

using System;
using Plugin.FirebasePushNotification;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;
namespace onlinefirebase
{
public partial class App : Application
{
public App()
{
InitializeComponent();
MainPage = new MainPage();

CrossFirebasePushNotification.Current.OnTokenRefresh += (s, p) =>
{
System.Diagnostics.Debug.WriteLine($"TOKEN : {p.Token}");
};
CrossFirebasePushNotification.Current.OnNotificationReceived += (s, p) =>
{
System.Diagnostics.Debug.WriteLine("Received");
};

}
protected override void OnStart()
{
}
protected override void OnSleep()
{
}
protected override void OnResume()
{
}
}
}

我已经验证了

.已启用后台模式 ->远程通知 .Info.plist -> "FirebaseAppDelegateProxyEnabled" boolean -> No

我已成功获取令牌，但无法收到通知。

问题基于苹果密钥，苹果密钥应该上传到Firebase云面板，它可以工作
