类型“通知”没有成员“名称” - Swift

Question

我正在尝试按照 firebase 文档将推送通知合并到我的项目中。但是，我遇到了一个无法解决的错误。 “类型‘通知’没有成员‘名称’”。提前致谢！

import UIKit
import Firebase

@main
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        FirebaseApp.configure()
        
        registerForPushNotifications(application)
        Messaging.messaging().delegate = self
        Messaging.messaging().subscribe(toTopic: "relationship") { (error) in
            print("subscribed to relationship topic..")
        }
        return true
    }
    
    func registerForPushNotifications(_ application: UIApplication){
        if #available(iOS 10.0, *) {
          // For iOS 10 display notification (sent via APNS)
          UNUserNotificationCenter.current().delegate = self
          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()
    }
        
    // 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 messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
      print("Firebase registration token: \(String(describing: fcmToken))")
      let dataDict:[String: String] = ["token": fcmToken ?? ""]
      NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
      // TODO: If necessary send token to application server.
      // Note: This callback is fired at each app startup and whenever a new token is generated.
    }
    
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("DEBUG: registered for notifications with device token: \(deviceToken)")
    }
   
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler(.banner)
    }

}

我在项目中安装的 pod：

• pod 'Firebase/Core'
• pod 'Firebase/Functions'
• pod 'Firebase/Analytics'
• pod 'Firebase/Auth'
• pod 'Firebase/Firestore'
• pod 'Firebase/Storage'
• pod 'Firebase/Messaging'

您自己的“通知”可能与基金会的“通知”冲突。如果您在通知前加上“NS”，应该可以解决这个问题。

NSNotification.Name
