ios - 在 IOS 10 swift 3 中未收到 FCM 通知

Question

长期以来，我一直在尝试在我的 iOS 应用程序中获取 firebase 推送通知。我已经尝试了我能在互联网上找到的所有内容。但遗憾的是没有运气。
任何帮助，将不胜感激。

我正在通过 firebase 控制台发送通知。有时当应用程序在前台运行时，最后一部分

extension AppDelegate : FIRMessagingDelegate {
    // Receive data message on iOS 10 devices.
    func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
        print("noti recieve remote notification in extesnion")
         print("%@ debug", remoteMessage)
        print("%@", remoteMessage.appData)

    }

被调用，但当应用程序处于后台时没有任何反应。我在功能中启用了“推送通知”和“后台模式”。

我只在 ios 10 设备上测试过。

这是我在 AppDelegate.swift 中的代码

import UIKit
import FirebaseMessaging
import Firebase
import UserNotifications
import FirebaseInstanceID

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


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


     /*   let notificationType : UIUserNotificationType = [UIUserNotificationType.alert, UIUserNotificationType.badge, UIUserNotificationType.sound]
        let notificationSettings: UIUserNotificationSettings =  UIUserNotificationSettings(types:notificationType,categories:nil)
        application.registerForRemoteNotifications()
        application.registerUserNotificationSettings(notificationSettings)*/

     if #available(iOS 10.0, *) {
            print("if ios 10 ")
            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

我通过将下面的代码添加到项目中解决了这个问题。

当您通过 TestFlight 安装应用程序时，将使用 FIRInstanceIDAPNSTokenType.Sandbox，
和 FIRInstanceIDAPNSTokenType.Prod，当您的应用在 App Store 上线时。

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) 
{
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type:FIRInstanceIDAPNSTokenType.Sandbox)
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type:FIRInstanceIDAPNSTokenType.Prod)
}
