ios - 如何在通过 Firebase Cloud Messaging 收到推送通知后显示角标(Badge)编号和声音？

Question

我正在尝试通过 Firebase 云消息传递向我的 iOS 应用程序实现推送通知。我可以完美地设置 firebase 控制台和 APN，我可以在我的设备中收到通过 Firebase 控制台发送的通知。

但是，当我收到通知时，它只显示警报，没有声音，角标(Badge)中没有数字，即使我已经说明了 UNAuthorizationOptions = [.alert, .badge, .sound]这是我在应用程序委托(delegate)中使用的代码

import UIKit
import Firebase
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate {

    var window: UIWindow?


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

        FirebaseApp.configure()


        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
        print("FCM token: \(token ?? "")")








        return true
    }



    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String){
        print("Firebase registration token: \(fcmToken)")

    }






}

我还在我的 Info.plist 中将 "FirebaseAppDelegateProxyEnabled" 设置为 YES。这是我的播客文件

# Uncomment the next line to define a global platform for your project
 platform :ios, '9.0'

target 'Firebase Push Notification' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Firebase Push Notification

    pod 'Firebase/Core'
    pod 'Firebase/Messaging'

end

那么如何在收到通知时添加声音和角标(Badge)呢？

Answer 1

您需要告诉您的服务/后端所有者发送与此类似的通知的负载。基本上，您需要有 badge 和 sound 键才能按预期工作:

{  
   "aps":{  
      "alert":"This is a message",
      "badge":1,
      "sound":"default"
   }
}
