Firebase Cloud Messaging AppDelegate錯誤

Question

這是Firebase文檔中的代碼。

if #available(iOS 10.0, *) { 
     let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound] 
     UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
      authOptions, 
      completionHandler: {_,_ in }) 

     // For iOS 10 display notification (sent via APNS) 
     UNUserNotificationCenter.currentNotificationCenter().delegate = self 
     // For iOS 10 data message (sent via FCM) 
     FIRMessaging.messaging().remoteMessageDelegate = self 

    } else { 
     let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil) 
     application.registerUserNotificationSettings(settings) 
    } 

我沒有修改任何代碼行。但Xcode說：「使用未申報類型UNAuthorizationOptions,UNUserNotificationCenter,FIRMessagingDelegate」

我還有一行。

NotificationCenter.defaultCenter.addObserver(self,selector: #selector(self.tokenRefreshNotification),name: kFIRInstanceIDTokenRefreshNotification,object: nil) 

它說「類型的AppDelegate的價值沒有成員tokenRefreshNotification」

我只是複製和火力文檔粘貼我的代碼，但有錯誤！

Answer 1

的例子在火力地堡文檔已經過時。下面是最近的Xcode 8和斯威夫特3代碼：

import Firebase 
import UserNotifications 

class AppDelegate: UIResponder, UIApplicationDelegate { 


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


     FIRApp.configure() 

     if #available(iOS 10.0, *) { 
      let authOptions : UNAuthorizationOptions = [.alert, .badge, .sound] 
      UNUserNotificationCenter.current().requestAuthorization(
       options: authOptions, 
       completionHandler: {_,_ in }) 

      // For iOS 10 display notification (sent via APNS) 
      UNUserNotificationCenter.current().delegate = self 
      // For iOS 10 data message (sent via FCM) 
      FIRMessaging.messaging().remoteMessageDelegate = self 

     } 

     application.registerForRemoteNotifications() 

     return true 
    } 
} 


@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 
     // Print message ID. 
     print("Message ID: \(userInfo["gcm.message_id"]!)") 

     // Print full message. 
     print("%@", userInfo) 

    } 

} 

extension AppDelegate : FIRMessagingDelegate { 
    // Receive data message on iOS 10 devices. 
    func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) { 
     print("%@", remoteMessage.appData) 
    } 
} 

Answer 2

您需要將以下導入添加到您的文件：

import Firebase 
import FirebaseMessaging 
import UserNotifications 

您還需要一個名爲tokenRefreshNotification類似於下面的方法：

func tokenRefreshNotification() { 
    let fcmDeviceToken = FIRInstanceID.instanceID().token() 
    // TODO: Send token to server 
}

Answer 4

適用於swift 2.0 添加FIRMessagingDelegate協議

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate{} 
func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage){} 

Answer 5

雨燕2.3的版本阿列克謝的回答將是：

if #available(iOS 10.0, *) { 
      let authOptions: UNAuthorizationOptions = [.Alert, .Badge, .Sound] 
      UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(authOptions, completionHandler: {_, _ in}) 

      // For iOS 10 display notification (sent via APNS) 
      UNUserNotificationCenter.currentNotificationCenter().delegate = self 
      // For iOS 10 data message (sent via FCM) 
      FIRMessaging.messaging().remoteMessageDelegate = self 

     } else { 
      let settings: UIUserNotificationSettings = 
       UIUserNotificationSettings(forTypes: [.Alert , .Badge, .Sound], categories: nil) 
      application.registerUserNotificationSettings(settings) 
     } 

     application.registerForRemoteNotifications() 

和..

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

    // Receive displayed notifications for iOS 10 devices. 

    func userNotificationCenter(center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) { 
     let userInfo = notification.request.content.userInfo 
     // Print message ID. 
     print("Message ID: \(userInfo["gcm.message_id"]!)") 

     // Print full message. 
     print("%@", userInfo) 

    } 

} 

extension AppDelegate : FIRMessagingDelegate { 
    // Receive data message on iOS 10 devices. 
    func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage) { 
     print("%@", remoteMessage.appData) 
    } 
}
