如何從iOS上的Firebase Cloud Messaging獲取令牌

Question

播客文件

target 'T' do
  use_frameworks!

  pod 'Firebase/Core'
  pod 'Firebase/Messaging'
  pod ‘Firebase’
  pod ‘Firebase/Auth’
  pod 'Firebase/Database'
  pod 'Firebase/Storage'
end

在AppDelegate.swift中導入

import UIKit
import CoreData
import Firebase
import UserNotifications
import FirebaseMessaging

AppDelegate

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate

運行Xcode 9.2，編譯器語言版本為swift 4，部署目標為11.2

根據文檔https://firebase.google.com/docs/cloud-messaging/ios/client，我應該可以使用以下內容

1) Messaging.messaging().delegate = self
2) func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
   print("Firebase registration token: \(fcmToken)")
 }

3) FIRMessageDelegate

但是xcode無法識別-1中的'Messaging'類-3中的'FIRMessageDelegate'-或2中的委托方法

因此，我無法獲取我的應用所需的fcmtoken

Xcode可以識別這些，但是這些不在文檔中，所以我不知道該怎么辦

4) FIRMessagingDelegate
5) FIRMessaging.messaging().remoteMessageDelegate = self

而4）中唯一的委托方法是

func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage)
    {
        print(remoteMessage.appData)
    }

我的問題是：我如何獲得代幣？ 該文檔似乎已過時。

在appdelegate中嘗試

import UIKit
import Firebase
import UserNotifications






@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate {

    var window: UIWindow?
    var fcmTokenUser : String?


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

        FirebaseApp.configure()


        print(NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).last! as String)


        // To get FCM token that will be sent to APNS via Google FCM
        if #available(iOS 10.0, *) {
            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate

            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
        let token = Messaging.messaging().fcmToken





        return true
    }



    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String){
         // This callback is fired at each app startup (when the user install the app for the very first time) and whenever a new token is generated due to The app is restored on a new device, The user uninstalls/reinstall the app, The user clears app data.

        // after fcm generated for the very first time,then fcm can also be retrieved in the 'didFinishLaunchingWithOptions' method above (let token = Messaging.messaging().fcmToken)


        fcmTokenUser = fcmToken






    }


    private func application(application: UIApplication,
                     didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
        Messaging.messaging().apnsToken = deviceToken as Data
    }





}

解決方案是，pod安裝正在安裝舊版本的firebase。 最新版本為4，但pod install正在安裝版本3。因此，要修復此問題，我需要進行pod更新，但是命令說無法連接到gitbub，所以我在這里做了這個家伙的工作Cocoapods：無法連接到GitHub更新CocoaPods / Specs規范倉庫 ，然后進行pod更新並升級了Firebase

Answer 3

不久前，我剛剛設法成功獲取了fcm令牌，並將通知從Firebase控制台發送到我的手機。 這是AppDelegage的完整代碼。 firebase.com文檔中的代碼似乎已過時。

import UIKit
import Firebase
import UserNotifications
import FirebaseMessaging

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(_ application: UIApplication, didFinishLaunchingWithOptions 
launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    FirebaseApp.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 as! 
UNUserNotificationCenterDelegate
        // For iOS 10 data message (sent via FCM)
        Messaging.messaging().delegate = self as! MessagingDelegate
    }

    application.registerForRemoteNotifications()

    return true
    }
}

func application(_ application: UIApplication, 
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken


}






func applicationWillResignActive(_ application: UIApplication) {
    // Sent when the application is about to move from active to inactive 
state. This can occur for certain types of temporary interruptions (such as 
an incoming phone call or SMS message) or when the user quits the application 
and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and invalidate 
graphics rendering callbacks. Games should use this method to pause the game.
}

func applicationDidEnterBackground(_ application: UIApplication) {
    // Use this method to release shared resources, save user data, 
invalidate timers, and store enough application state information to restore 
your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is 
called instead of applicationWillTerminate: when the user quits.
}

func applicationWillEnterForeground(_ application: UIApplication) {
    // Called as part of the transition from the background to the active 
state; here you can undo many of the changes made on entering the background.
}

func applicationDidBecomeActive(_ application: UIApplication) {
    // Restart any tasks that were paused (or not yet started) while the 
application was inactive. If the application was previously in the 
background, optionally refresh the user interface.
}

func applicationWillTerminate(_ application: UIApplication) {
    // Called when the application is about to terminate. Save data if 
appropriate. See also applicationDidEnterBackground:.
}


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

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: 
String){

    print("token: \(fcmToken)")


}
}
