设置 firebase 通知

Question

因此，我一直致力于使用云消息传递设置 firebase 通知，但遇到了问题。 我一直在学习本教程，所以如果我做错了什么（希望我没有做错），请告诉我。 我也一直在看这个。

这是我的 AppDelegate 代码，这是他们告诉我放置所有东西的地方。 我也做了证书的事情，希望它能正常工作：

import UIKit
import Firebase
import FirebaseMessaging

class AppDelegate: NSObject, UIApplicationDelegate {
  func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions
      launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil
  ) -> Bool {
      
      FirebaseApp.configure()
      // 2
      FirebaseConfiguration.shared.setLoggerLevel(.min)
      
      UNUserNotificationCenter.current().delegate = self
      // 2
      let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
      UNUserNotificationCenter.current().requestAuthorization(
        options: authOptions) { _, _ in }
      // 3
      application.registerForRemoteNotifications()
      
      Messaging.messaging().delegate = self //Here is one of the problems
    return true
  }
}
    
    // MARK: UISceneSession Lifecycle

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        // Called when a new scene session is being created.
        // Use this method to select a configuration to create the new scene with.
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
        // Called when the user discards a scene session.
        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}

extension AppDelegate: UNUserNotificationCenterDelegate {
  func userNotificationCenter(
    _ center: UNUserNotificationCenter,
    willPresent notification: UNNotification,
    withCompletionHandler completionHandler:
    @escaping (UNNotificationPresentationOptions) -> Void
  ) {
    completionHandler([[.banner, .sound]])
  }

  func userNotificationCenter(
    _ center: UNUserNotificationCenter,
    didReceive response: UNNotificationResponse,
    withCompletionHandler completionHandler: @escaping () -> Void
  ) {
    completionHandler()
  }
}

func application(
  _ application: UIApplication,
  didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data
) {
  Messaging.messaging().apnsToken = deviceToken //Here's the other problem
}

extension AppDelegate: MessagingDelegate {
  func messaging(
    _ messaging: Messaging,
    didReceiveRegistrationToken fcmToken: String?
  ) {
    let tokenDict = ["token": fcmToken ?? ""]
    NotificationCenter.default.post(
      name: Notification.Name("FCMToken"),
      object: nil,
      userInfo: tokenDict)
  }
}

问题：

Type 'Messaging' has no member 'messaging'

Answer 1

您可能正在使用旧版本的 pod 或依赖项。

FIRMessaging.messaging().delegate = self

上面的代码将为您工作。

选择

如果您使用的是 pod，则可以使用以下命令进行更新。

pod update Firebase/Messaging

要不就

pod update

上面的命令将更新您的所有 pod，请小心。

Answer 2

好极了。 我找到了解决方案。 其实很简单。 我不小心在我的名为 Messaging 的应用程序中有一个 swift 视图，它丢弃了语法。

如果你遇到这个问题。 确保项目中没有任何名称名为 Messaging。
