Swift 3 - ローカル通知のdidReceiveRemoteNotification機能が起動されない

Question

私は通知をスケジュールし、アプリケーションが実行中であるか、フォアグラウンドで実行されていないときにユーザーに表示することができました。この通知のタップにViewControllerと表示する必要があります。

didReceiveRemoteNotificationは、ユーザーが通知をタップしたときに呼び出される関数だと思います。私の場合、この機能は決して発動されません。

AppDelegate：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

    let center = UNUserNotificationCenter.current() 
    center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in 
      // Enable or disable features based on authorization. 
     } 

     return true 
} 

//didReceiveRemoteNotification goes here 

didReceiveRemoteNotification機能：

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) { 
     if (application.applicationState == UIApplicationState.active) 
     { 
      print("Active") 
      // App is foreground and notification is recieved, 
      // Show a alert. 
     } 
     else if(application.applicationState == UIApplicationState.background) 
     { 
      print("Background") 
      // App is in background and notification is received, 
      // You can fetch required data here don't do anything with UI. 
     } 
     else if(application.applicationState == UIApplicationState.inactive) 
     { 
      print("Inactive") 
      // App came in foreground by used clicking on notification, 
      // Use userinfo for redirecting to specific view controller. 
     } 
} 

これは私のAppDelegate全体の通知関連のコードです。何か不足していますか？あなたはUNUserNotificationCenterDelegateで動作するので、AppDelegateでUNUserNotificationCenterDelegateを実装し、didFinishLaunchingWithOptions方法でデリゲートを設定する必要がUserNotifications枠組みについては

。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

    let center = UNUserNotificationCenter.current() 
    center.delegate = self 
    center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in 
     // Enable or disable features based on authorization. 
    } 

    return true 
} 

今、あなたは、通知を得るためにuserNotificationCenter(_:willPresent:withCompletionHandler:)とuserNotificationCenter(_:didReceive:withCompletionHandler:)のメソッドを実装する必要があります。

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { 

    //Handle notification 
} 

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping() -> Void) { 
    // pull out the buried userInfo dictionary 
    let userInfo = response.notification.request.content.userInfo 

    if let customData = userInfo["customData"] as? String { 
     print("Custom data received: \(customData)") 

     switch response.actionIdentifier { 
     case UNNotificationDefaultActionIdentifier: 
      // the user swiped to unlock 
      print("Default identifier") 

     case "show": 
      // the user tapped our "show more info…" button 
      print("Show more information…") 
      break 

     default: 
      break 
     } 
    } 

    // you must call the completion handler when you're done 
    completionHandler() 
}
