如何修正 Firebase 通知应用代理中使用的此已弃用代码?

Question

如何在 Swift 4 中使用以下在 iOS 10 中已弃用的代码？此应用程序用于使用 Firebase 发送推送通知。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let notificationTypes : UIUserNotificationType = [UIUserNotificationType.alert, UIUserNotificationType.badge, UIUserNotificationType.sound]
let notificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
application.registerForRemoteNotifications()
application.registerUserNotificationSettings(notificationSettings)

return true
}

和

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
// Print message ID.
print("Message ID: (userInfo["gcm.message_id"]!)")
print(userInfo)
}

任何帮助不胜感激，谢谢。

现在，我在使用 Firebase 通知的应用中执行此操作。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
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 })
// For iOS 10 data message (sent via FCM)
Messaging.messaging().remoteMessageDelegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
FirebaseApp.configure()
}
