在iOS设备上未收到FCM推送通知

Question

我已遵循外部指南在iOS Swift应用（link）中通过FCM实现推送通知，但通过Firebase控制台进行的测试无法正常工作。我已经测试了将消息作为通用消息发送到特定令牌的情况-在真正的iOS设备上无法正常工作。

我做了以下事情：

• 生成的APN密钥并上传到Firebase
• 已启用推送通知+后台远程通知

请在代码下方找到

用户注册后：

let pushManager = PushNotificationManager(userID: userID)
pushManager.registerForPushNotifications()

班级：

import Firebase
import FirebaseFirestore
import FirebaseMessaging
import UIKit
import UserNotifications

class PushNotificationManager: NSObject, MessagingDelegate, UNUserNotificationCenterDelegate {
    let userID: String
    init(userID: String) {
        self.userID = userID
        super.init()
    }
    func registerForPushNotifications() {
        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 })
            // For iOS 10 data message (sent via FCM)
            Messaging.messaging().delegate = self
        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            UIApplication.shared.registerUserNotificationSettings(settings)
        }
        UIApplication.shared.registerForRemoteNotifications()
        updateFirestorePushTokenIfNeeded()
    }

    func updateFirestorePushTokenIfNeeded() {
        if let token = Messaging.messaging().fcmToken {
            let usersRef = Firestore.firestore().collection("Users").document(userID)
            usersRef.setData(["fcmToken": token], merge: true)
        }
    }
    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
        print(remoteMessage.appData)
    }
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        updateFirestorePushTokenIfNeeded()
    }
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        print(response)
    }
}
