当应用程序被杀死时 ios 通知 firebase 重定向特定 View

Question

早上好，开发一个应用程序，我使用 firebase 接收通知，如果我发送通知并且应用程序被终止，我会遇到问题，我打开应用程序的第一页，而不是我想打开一个特定的 View ，这是我的代码

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

    FirebaseApp.configure ()


    // locally save data for settings

    let launchedBefore = UserDefaults.standard.bool (forKey: "launchedBefore")
    if launchedBefore {
        print ("Not first launch.")
    } else {
        print ("First launch, setting UserDefault.")
        UserDefaults.standard.set (true, forKey: "isNotify")
        UserDefaults.standard.set (false, forKey: "isZoom")
        UserDefaults.standard.set (true, forKey: "isCookie")
        if UserDefaults.standard.bool (forKey: "isNotify") {
            registerNotification ()
        }
        UserDefaults.standard.set (true, forKey: "launchedBefore")
    }
    NotificationCenter.default.addObserver (self, selector: #selector (registerNotification), name: NSNotification.Name (rawValue: "isNotify"), object: nil)
    return true
}

func registerNotification () {
    if #available (iOS 10, *) {
        UNUserNotificationCenter.current (). RequestAuthorization (options: [. Badge, .alert, .sound]) {(granted, error) in}
        UIApplication.shared.registerForRemoteNotifications ()
    }
        // iOS 9 support
    else {
        UIApplication.shared.registerUserNotificationSettings (UIUserNotificationSettings (types: [.badge, .sound, .alert], categories: nil))
        UIApplication.shared.registerForRemoteNotifications ()
    }
}

在 didFinishLaunchingWithOptions 方法中，像这样阅读通知:

        let notification = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? NSDictionary
    if notification != nil {
        // Read the notification payload and open related page
    }
