的UITableViewCell：UITapGestureRecognizer無法識別的選擇發送到實例錯誤

Question

我有一個UILabel一個UITapGestureRecognizer在UITableViewCell，我添加所述UITapGestureRecognizer的目標作爲視圖控制器，如：

class Cell: UITableViewCell { 

    @IBOutlet weak var label: UILabel! 
    override func awakeFromNib() { 
     super.awakeFromNib() 
     let tap1 = UITapGestureRecognizer(target: ViewController(), action: "selectLabel:") 
     label.addGestureRecognizer(tap) 
    } 
} 

class ViewController: UIViewController,UITableViewDataSource, UITableViewDelegate{ 

    fun selectLabel(gesture: UITapGestureRecognizer){ 
     //animate some view in custom cell 
    } 
} 

然而，我得到一個「UITapGestureRecognizer無法識別的選擇器發送到實例」錯誤。

上cellForRowAtIndexPath.

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCellWithIdentifier("CellIdentifier", forIndexPath: indexPath) as! Cell 
    let tap1 = UITapGestureRecognizer(target: self, action: "selectLabel:") 
    cell.label.addGestureRecognizer(tap1) 
    return cell 
    }
