Question

我终于可以在两个应用之间通过Firebase发送推送通知。问题是，只有在设备上全新安装后，App1上的作品才起作用。如果我停止并再次运行，即使fcmToken未被更改，项目推送通知也不再传递，并且在App2中我收到错误消息：

POST: 
    {"multicast_id":6763498783850594663,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"NotRegistered"}]}

表示Firebase找不到有效的fcmToken来发送推送。在App1上时，首先安装控制台打印：

didReceiveRegistrationToken：Firebase注册令牌： eI8nx-zroBU：APA91bG9gZeukgfsxobw4C3mg0Jhro06ALUQqtJwjfYxIwv4hIvjFwNWpSc_0JHPtl2FAGb-Jqwk7GL5pgki_Q_awOngA8yP66IG9FpWKQDUB>

我在didReceiveRegistrationToken委托方法中进行设置时，

是正确的，在第二次启动时didReceiveRegistrationToken给出的令牌与以前相同。据我了解，是否有新的fcmToken被调用，didRefreshRegistrationToken会被调用，但是我没有从该委托方法中获取任何打印品，所以看来以前的fcmToken仍然有效。您能看到我在哪里设置错误吗？

didFinishLaunchingWithOptions：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        window?.tintColor = UIColor.blue
        // Use Firebase library to configure APIs
        FirebaseApp.configure()
        Messaging.messaging().delegate = self
        Crashlytics().debugMode = true
        Fabric.with([Crashlytics.self])
        // setting up notification delegate
        if #available(iOS 10.0, *) {
            //iOS 10.0 and greater
            UNUserNotificationCenter.current().delegate = self
            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            //Solicit permission from the user to receive notifications
            UNUserNotificationCenter.current().requestAuthorization(options: authOptions, completionHandler: { granted, error in
                DispatchQueue.main.async {
                    if granted {
                        print("didFinishLaunchingWithOptions iOS 10: Successfully registered for APNs")
                        UIApplication.shared.registerForRemoteNotifications() // declaring it work perfetcly
                        UIApplication.shared.applicationIconBadgeNumber = 0
                    } else {
                        //Do stuff if unsuccessful...
                        print("didFinishLaunchingWithOptions iOO 10: Error in registering for APNs: \(String(describing: error))")
                    }
                }
            })
        } else {
            //iOS 9
            let type: UIUserNotificationType = [UIUserNotificationType.badge, UIUserNotificationType.alert, UIUserNotificationType.sound]
            let setting = UIUserNotificationSettings(types: type, categories: nil)
            UIApplication.shared.registerUserNotificationSettings(setting)
            UIApplication.shared.registerForRemoteNotifications() // declaring it work perfetcly
            UIApplication.shared.applicationIconBadgeNumber = 0
            print("didFinishLaunchingWithOptions iOS 9: Successfully registered for APNs")
        }
        //get application instance ID
//        InstanceID.instanceID().instanceID { (result, error) in
//            if let error = error {
//                print("didFinishLaunchingWithOptions: Error fetching remote instance ID: \(error)")
//            } else if let result = result {
//                print("didFinishLaunchingWithOptions: Remote instance ID token: \(result.token)")
//            }
//        }
        // setting up remote control values
        let _ = RCValues.sharedInstance
        GIDSignIn.sharedInstance().clientID = FirebaseApp.app()?.options.clientID
        Crashlytics().debugMode = true
        Fabric.with([Crashlytics.self])
        //        // TODO: Move this to where you establish a user session
        //        self.logUser()
        var error: NSError?
        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        } catch let error1 as NSError{
            error = error1
            print("could not set session. err:\(error!.localizedDescription)")
        }
        do {
            try AVAudioSession.sharedInstance().setActive(true)
        } catch let error1 as NSError{
            error = error1
            print("could not active session. err:\(error!.localizedDescription)")
        }
        // goggle only
        GIDSignIn.sharedInstance().clientID = FirebaseApp.app()?.options.clientID
//        GIDSignIn.sharedInstance().delegate = self
        // Facebook SDK
        return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
//        return true
    }

didRegisterForRemoteNotificationsWithDeviceToken：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let tokenParts = deviceToken.map { data -> String in
            return String(format: "%02.2hhx", data)
        }
        let token = tokenParts.joined()
        print(" didRegisterForRemoteNotificationsWithDeviceToken : devcice token is: \(token)")
        Messaging.messaging().apnsToken = deviceToken
    }

didReceiveRegistrationToken：

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        print("didReceiveRegistrationToken: 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.
        AppDelegate.fcmToken = fcmToken

        if userDetails.fullName != nil {
            userDetails.fcmToken = fcmToken
            Firebase.updateToken(completed: { (true) in
                print("AppDelegate.didFinishLaunchingWithOptions: token updloaded to Firebase, will now save it to CoreData")
            }, token: fcmToken)
        }
        // Note: This callback is fired at each app startup and whenever a new token is generated.
    }

didRefreshRegistrationToken：

func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
        let dataDict:[String: String] = ["token": fcmToken]
        NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
//        print("Refreshed Token: \(fcmToken)")
        AppDelegate.fcmToken = fcmToken
        if userDetails.fullName != nil {
            userDetails.fcmToken = fcmToken
            Firebase.updateToken(completed: { (true) in
                print("AppDelegate.didRefreshRegistrationToken: token updloaded to Firebase, will now save it to CoreData")
            }, token: fcmToken)
        }
    }

问题似乎已解决。更新容器之后，它现在可以按预期工作。我不得不从设备中删除App1并重新安装它，因为我第一次尝试再次运行项目的速度仍然很快。清理构建后，从设备中删除该应用并重新安装该应用，现在在我重新启动该项目后，它始终会收到推送通知。希望这对其他人有帮助，因为我在实现设备到设备的推送通知方面付出了很多努力，并且还没有找到很多有用的信息。

从Xcode Swift重新启动应用程序后，不再发送推送通知
