返回到详细页面的表格视图，无需重新加载，Swift

Question

我的表格视图包含每个单元格的详细信息按钮。当我单击该按钮时，它将转到有关该单元格的详细信息页面。在详细信息页面中，有一个“后退”按钮。当我单击它时，它可以返回到表视图，但重新加载表视图。我的问题是如何在不重新加载表格视图的情况下返回。我只想回到单击详细信息按钮的单元格。

谢谢， 贝

  

TableViewController

    override func viewDidLoad() {
    super.viewDidLoad()

    let theWidth = view.frame.size.width
    let theHeight = view.frame.size.height

    resultsTable.frame = CGRectMake(0, 0, theWidth, theHeight)
    // Do any additional setup after loading the view.

    refresher = UIRefreshControl()
    refresher.tintColor = UIColor.blackColor()
    refresher.addTarget(self, action: "refresh", forControlEvents: UIControlEvents.ValueChanged)
    self.resultsTable.addSubview(refresher)
}

  }


  @IBAction func backButtonTapped(sender: AnyObject) {
     self.dismissViewControllerAnimated(true, completion: nil)
  }
