FireBase通知

Question

在我的应用程序中，我使用Firebase接收通知，但遇到问题：当我从Firebase控制台发送通知时，我没有任何通知。同一个发送设备使用令牌保存为所有iOS。

import UIKit 
import UserNotifications 

import Firebase 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 
    let gcmMessageIDKey = "gcm.message_id" 

    func application(_ application: UIApplication, 
        didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

     FirebaseApp.configure() 

     Messaging.messaging().delegate = self 

     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() 

     return true 
    } 

    // [START receive_message] 
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) { 

     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 let messageID = userInfo[gcmMessageIDKey] { 
      print("Message ID: \(messageID)") 
     } 

     // Print full message. 
     print(userInfo) 

     completionHandler(UIBackgroundFetchResult.newData) 
    } 
    // [END receive_message] 
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { 
     print("Unable to register for remote notifications: \(error.localizedDescription)") 
    } 

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { 
     print("APNs token retrieved: \(deviceToken)") 
    } 
} 

@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 

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

     // Print full message. 
     print(userInfo) 

     completionHandler([]) 
    } 

    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, didRefreshRegistrationToken fcmToken: String) { 
     print("Firebase registration token: \(fcmToken)") 
    } 

    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) { 
     print("Received data message: \(remoteMessage.appData)") 
    } 
} 

我在推送通知功能，并添加到项目GoogleServise-的info.plist

我遵循here官方指南，但它不工作。

你可以试试这个

func userNotificationCenter(_ center: UNUserNotificationCenter, 
           willPresent notification: UNNotification, 
           withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { 
     let userInfo = notification.request.content.userInfo 

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

     // Print full message. 
     print(userInfo) 

     // completionHandler([]) 

     completionHandler([.alert, .badge, .sound]) 

    }

你最有可能跳过这一步，我做了我第一次配置火力地堡云消息：
