ios - Firebase 云消息传递不适用于 IOS

Question

所以我已经尝试解决这个问题一段时间了，我已经按照设置指南进行了几次操作，但我什至无法让从 firebase 控制台发送的推送通知显示出来。我设置并运行了 Phone Auth，这需要推送通知和 APN 设置，与 FCM 相同。这是我的 AppDelegate 文件:

对于 FCM，您不需要使用 InstanceID 和 FirabaseAuth 并且没有它们我可以使用从我的应用程序以编程方式发送 APNS 到订阅的主题

我的 pod 只包含

pod 'Firebase/Messaging'

工作代码如下:

 //MARK:- Push Notification
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    //  Register.
    let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
    print("deviceTokenString: \(deviceTokenString)")
    self.apnsToken = deviceTokenString

    //set apns token in messaging
    Messaging.messaging().apnsToken = deviceToken

    //get FCM token
    if let token = Messaging.messaging().fcmToken {
        self.fcmToken = token
        print("FCM token: \(token)")
    }

    //subscribe to topic to send message to multiple device
    self.subscribeToTopic()
}

通过如下给出的主题以编程方式将 APNS 发送到所有设备:

func sendPushMessage(todoItem:TodoItem, isAdded:Bool = true) {

  let url = URL(string: "https://fcm.googleapis.com/fcm/send")!
  var request = URLRequest(url: url)
  request.httpMethod = "POST"
  request.setValue("application/json", forHTTPHeaderField: "Content-Type")
  let strKey:String = "Here FCM Server Key"
  request.setValue("key=\(strKey)", forHTTPHeaderField: "Authorization")

  var message:String = ""
  if isAdded {
    message = "Todo with title '\(todoItem.title)' added"
  }
  else{
    message = "Todo with title '\(todoItem.title)' removed"
  }

  let dictData = ["to":"/topics/alldevices","priority":"high","notification":["body":message,"title":"Community","badge":"1"]] as [String : Any]

  do {
     let jsonData = try JSONSerialization.data(withJSONObject: dictData, options: .prettyPrinted)
     // here "jsonData" is the dictionary encoded in JSON data

     request.httpBody = jsonData

     let task = URLSession.shared.dataTask(with: request, completionHandler: { (responseData: Data?, response: URLResponse?, error: Error?) in

        let strData :String = String(data: responseData!, encoding: String.Encoding.utf8)!
        print("data : \(strData)")
        NSLog("\(String(describing: response) )")
    })
    task.resume()

  } catch {
    print(error.localizedDescription)
  }
}
