選擇自定義單元格激活另一個細胞

我有了圖像，幾個文本標籤（1截斷）的自定義單元格類，和一個按鈕：選擇自定義單元格激活另一個細胞

class CustomTVC: UITableViewCell { 

    /* Outlets */ 
    @IBOutlet weak var imageHolder: UIImageView! 
    @IBOutlet weak var concatenatedTitleHolder: UILabel! 
    @IBOutlet weak var localDateHolder: UILabel! 
    @IBOutlet weak var descriptionHolder: UILabel! 
    @IBOutlet weak var seeMoreButton: UIButton! 

    override func awakeFromNib() { 
     super.awakeFromNib() 
    } 
}

當在用戶點擊按鈕，它顯示截斷的文本標籤的完整描述。但是，我現在遇到的問題是，當用戶單擊特定單元的按鈕時，它會顯示用戶單擊的單元的完整描述，以及另一個單元的完整描述。

我知道發生的原因是因爲tableview通過dequeueReusableCellWithIdentifier重用了單元。我將如何去實現一個函數，以確保當用戶點擊特定單元的按鈕時，只顯示該單元的完整描述？

代碼實現代碼如下：

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let cell = self.tableView.dequeueReusableCellWithIdentifier("customCell", forIndexPath: indexPath) as! CustomTVC 

    if listOfShows.count != 0 { 
     // Downloading and displaying picture 
     if let downloadPicture: UIImage = helperFunctions.downloadImage(listOfShows[indexPath.row].imageLink) { 
      cell.imageHolder.image = downloadPicture 
     } 
     // Enlarging/dismissing picture 
     cell.imageHolder.userInteractionEnabled = true 
     let newTapped = UITapGestureRecognizer(target: self, action: #selector(MainTVC.imagedTapped(_:))) 
     cell.imageHolder.addGestureRecognizer(newTapped) 
     // Concatenating channel + series + episode title 
     let concatenatedTitle = listOfShows[indexPath.row].channel + " " + listOfShows[indexPath.row].series + " " + listOfShows[indexPath.row].episodeTitle 
     // Converting into local date/time 
     let universalTime = helperFunctions.localDateAndTimeConverter(listOfShows[indexPath.row].originalAirDate) 

     /* Other labels */ 
     cell.concatenatedTitleHolder.text = concatenatedTitle 
     cell.localDateHolder.text = universalTime 
     cell.descriptionHolder.text = listOfShows[indexPath.row].description 

     cell.seeMoreButton.tag = indexPath.row 
     cell.seeMoreButton.addTarget(self, action: #selector(MainTVC.buttonTapped(_:markedArray:)), forControlEvents: .TouchUpInside) 

     resetCellSettings(cell) 
    } 
    return cell 
} 

func buttonTapped(sender: UIButton, markedArray: [Bool]) { 

    let indexPath = NSIndexPath(forRow: sender.tag, inSection: 0) 
    let cell = tableView.cellForRowAtIndexPath(indexPath) as! CustomTVC 

    cell.seeMoreButton.hidden = true 
    cell.descriptionHolder.numberOfLines = 0 
    cell.descriptionHolder.lineBreakMode = NSLineBreakMode.ByWordWrapping 
    cell.descriptionHolder.sizeToFit() 
} 

func resetCellSettings(cell: CustomTVC) { 
    cell.seeMoreButton.hidden = false 
    cell.descriptionHolder.numberOfLines = 1 
    cell.descriptionHolder.lineBreakMode = NSLineBreakMode.ByTruncatingTail 
    cell.descriptionHolder.sizeToFit() 
}

你應該把buttonTapped FUNC在CustomTVC類。並且在單元格創建時爲該func設置seeMoreButton的出口IBAction。
