ios - Firebase 推送通知

Question

我的 FCM 可以正常工作，但我无法让传统的横幅通知正常工作。

这是我的 AppDelegate.swift 文件中的内容:

import UIKit
import Firebase
import UserNotifications

@UIApplicationMain
final class AppDelegate: UIResponder {
  var window: UIWindow?

  override init() {
    super.init()    
    FIRApp.configure()
  }
}

// MARK: - UIApplicationDelegate
extension AppDelegate: UIApplicationDelegate {
  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
    let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
    UNUserNotificationCenter.current().requestAuthorization(options: authOptions, completionHandler: { _, _ in })
    UNUserNotificationCenter.current().delegate = self

    FIRMessaging.messaging().remoteMessageDelegate = self

    application.registerForRemoteNotifications()

    NotificationCenter.default.addObserver(self, selector: #selector(tokenRefreshNotification), name: .firInstanceIDTokenRefresh, object: nil)
    return true
  }

  func tokenRefreshNotification(notification: Notification) {
    if let refreshedToken = FIRInstanceID.instanceID().token() {
      print("InstanceID token: \(refreshedToken)")
    }

    connectToFcm()
  }

  func connectToFcm() {
    FIRMessaging.messaging().connect { error in
      if error != nil {
        print("Unable to connect with FCM. \(error)")
      } else {
        print("Connected to FCM.")
      }
    }
  }

  func applicationDidBecomeActive(_ application: UIApplication) {
    connectToFcm()
  }
}

// MARK: - UNUserNotificationCenterDelegate
extension AppDelegate: UNUserNotificationCenterDelegate {
  func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    let userInfo = notification.request.content.userInfo

    print("Message ID: \(userInfo["gcm.message_id"]!)")

    print(userInfo)

    completionHandler([.alert, .sound])
  }
}

// MARK:
extension AppDelegate: FIRMessagingDelegate {
  func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
    print("FIRMessagingRemoteMessage Received: \(remoteMessage.appData)")
  }
}

一切都是根据 documentation 配置的。当我通过 Firebase 上的通知控制台向我的应用发送消息时，我会收到控制台输出。

但是，发送通知时不会出现横幅。当应用程序处于后台时，通知似乎也不会发送 - 仅当应用程序位于前台时。

寻求帮助。提前致谢!

尝试禁用方法调配。

将 FirebaseAppDelegateProxyEnabled 添加到 info.plist 并将其设置为 NO。

然后将此代码添加到应用程序委托(delegate)

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
  FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenTypeSandbox)
}

从设备中删除您的应用并重新安装。 请测试是否调用了 application:didRegisterForRemoteNotificationsWithDeviceToken 。如果调用了，现在尝试从 firebase 控制台发送通知。
