Question

我已经在Xcode 11.5中开发了一个iOS应用程序，并且运行良好。但是，当我尝试配置Firebase Cloud Messaging推送通知时，它不起作用！

我已经按照Firebase控制台上的说明连接了该应用程序，原因是Firebase帐户已正确链接。这是我的AppDelegate.swift：

import UIKit
import Firebase
import FirebaseInstanceID
import FirebaseMessaging
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, QBRTCClientDelegate {

    let gcmMessageIDKey = "gcmMessageIDKey"
    
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
        FirebaseApp.configure()
        if #available(iOS 10.0, *) {
          // For iOS 10 display notification (sent via APNS)
          UNUserNotificationCenter.current().delegate = self

          let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
          UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })
        } else {
          let settings: UIUserNotificationSettings =
          UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
          application.registerUserNotificationSettings(settings)
        }

        application.registerForRemoteNotifications()
        Messaging.messaging().delegate = self
        
        return true
    }
    
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
      // 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.
      // TODO: Handle data of notification

      // With swizzling disabled you must let Messaging know about the message, for Analytics
      // Messaging.messaging().appDidReceiveMessage(userInfo)

      // Print message ID.
      if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
      }

      // Print full message.
      print(userInfo)
    }

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
      // 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.
      // TODO: Handle data of notification

      // With swizzling disabled you must let Messaging know about the message, for Analytics
      // Messaging.messaging().appDidReceiveMessage(userInfo)

      // Print message ID.
      if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
      }

      // Print full message.
      print(userInfo)

      completionHandler(UIBackgroundFetchResult.newData)
    }

}

@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {

  // Receive displayed notifications for iOS 10 devices.
  func userNotificationCenter(_ center: UNUserNotificationCenter,
                              willPresent notification: UNNotification,
    withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    let userInfo = notification.request.content.userInfo

    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)

    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
      print("Message ID: \(messageID)")
    }

    // Print full message.
    print(userInfo)

    // Change this to your preferred presentation option
    completionHandler([[.alert, .sound]])
  }

  func userNotificationCenter(_ center: UNUserNotificationCenter,
                              didReceive response: UNNotificationResponse,
                              withCompletionHandler completionHandler: @escaping () -> Void) {
    let userInfo = response.notification.request.content.userInfo
    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
      print("Message ID: \(messageID)")
    }

    // Print full message.
    print(userInfo)

    completionHandler()
  }
}

extension AppDelegate: MessagingDelegate {
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        InstanceID.instanceID().instanceID { (result, error) in
          if let error = error {
            print("Error fetching remote instance ID: \(error)")
          } else if let result = result {
            print("Remote instance ID token: \(result.token)")
          }
        }
        print("Firebase registration token: \(fcmToken)")

        let dataDict:[String: String] = ["token": fcmToken]
        NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
        // TODO: If necessary send token to application server.
        // Note: This callback is fired at each app startup and whenever a new token is generated.
        Messaging.messaging().isAutoInitEnabled = true
    }
}

我在项目中安装了Firebase / Core，Firebase / Analytics和Firebase / Messaging窗格。我将FirebaseAppDelegateProxyEnabled添加到Info.plist并将其设置为NO。

我还通过Apple开发人员帐户设置了Production APNS，我认为设置正确。

我已经测试了从终端本地发送“推送通知”，并且可以正常工作。

但是问题是，当我从Firebase控制台执行测试通知时，没有收到通知。

请提供有关如何解决此问题的建议。

Firebase FCM推送通知不适用于iOS Swift
