在 Swift 3 中单击处于终止/关闭状态的推送通知时，应用程序无法打开

如何打开一个Application当应用程序处于killed/closed状态，我收到通知，但当我单击通知应用程序时未打开，但当应用程序位于前台或后台时工作正常。我尝试了下面的代码仍然无法解决问题所在。请检查我尝试过的内容

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

        center.requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(grant, error)  in
            if error == nil {
                if grant {
