通知がクリックされたとき、IOSの目的のページにリダイレクトする必要があります

Question

FCM通知では、ユーザーが通知をクリックすると、ホームページにリダイレクトされますが、ホームページ以外の特定のページにリダイレクトしたいのですが、アプリがフォアグラウンドにあります。特定のページにリダイレクトされた場合、アプリは通知のデータを読み取り、ページにデータを表示する必要があります。

上記のアイデアを表すコードは次のとおりですが、ホームページにリダイレクトされ、何も起こりません（表示データなど）。

このコードをdidReceive Responseそのような方法：

 func userNotificationCenter(_ center: UNUserNotificationCenter,
                                    didReceive response: UNNotificationResponse,
                                    withCompletionHandler completionHandler: @escaping () -> Void) {
            let userInfo = response.notification.request.content.userInfo
            // Print message ID.
            if let messageID = userInfo[gcmMessageIDKey] {
                print("Message ID: \(messageID)")
            }

            // Print full message.
            print(userInfo)

    let storyBoard: UIStoryboard = UIStoryboard(name: "yourStoryboardName", bundle: nil)
        let presentViewController = storyBoard.instantiateViewController(withIdentifier: "yourViewControllerStoryboardID") as! YourViewController

        presentViewController.yourDict = userInfo //pass userInfo data to viewController
self.window?.rootViewController = presentViewController
                presentViewController.present(presentViewController, animated: true, completion: nil)

            completionHandler()
        }
    }

アプリケーションが実行されていません

アプリが閉じた状態のときは、didFinishLaunchingWithOptionsで起動オプションを確認する必要があります

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

    let storyBoard = UIStoryboard(name: "Main", bundle: nil)

    var viewController = UIViewController() 

    if (launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? NSDictionary) != nil {
        viewController = storyBoard.instantiateViewController(withIdentifier: "storyboardIdentifier") // user tap notification
    }else{
        viewController = storyBoard.instantiateViewController(withIdentifier: "storyboardIdentifier") // User not tap notificaiton
    }
    self.window?.rootViewController = viewController
    self.window?.makeKeyAndVisible()
}

フォアグラウンド状態のアプリケーションここで、特定のビューコントローラーにリダイレクトできます

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

        // Print full message.
        print(userInfo)

        let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let presentViewController = storyBoard.instantiateViewController(withIdentifier: "storyboardIdentifier") as! YourViewController

        presentViewController.yourDict = userInfo //pass userInfo data to viewController
        self.present(presentViewController, animated: true, completion: nil)

        completionHandler()
    }
}

通知を処理するための2つのメソッドを実装する必要があります。1つはアプリがバックグラウンドにあるとき、もう1つはアプリがシャットダウンして実行されていないときです。

AppDelegate内にapplication(_:didFinishLaunchingWithOptions:) -> Boolメソッドを実装します。これは、アプリが実行されていない場合に使用します。

_func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]?) -> Bool {
    if let notificationData = launchOptions?[.remoteNotification] {
        // Use this data to present a view controller based
        // on the type of notification received
    }
    return true
}
_

アプリがバックグラウンドにある場合、userNotificationCenter(_:didReceive:withCompletionHandler:)メソッドを実装する必要があります。

_func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        let notificationData = response.notification.request.content.userInfo
        // Use this data to present a view controller based
        // on the type of notification received
        completionHandler()
    }
_
