如何獲得自定義單元格標籤時，segue？

Question

我想獲取自定義單元格中所選行的名稱。我如何在Swift中做到這一點？

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 

    var selectedCell = CustomCell() 
    selectedCell = tableView(tbl, cellForRowAtIndexPath: <#NSIndexPath#>) 

    if(segue.identifier == "next") { 
     var next = (segue.destinationViewController as! EngineViewController) 
     next.titleSub = selectedCell.cell.lblBrand.text 
    } 
} 

Answer 1

我相信如果你只是選擇一個單元格，單元格應該是發件人。試試這個

if let selectedCell = sender as? CustomCell { 
    if(segue.identifier == "next") { 
    var next = (segue.destinationViewController as! EngineViewController) 
    next.titleSub = selectedCell.cell.lblBrand.text 
    } 
} 

Answer 2

你可以嘗試覆蓋didSelectRowAtIndexPath來獲取你的單元格。

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
let cell = tableView.dequeueReusableCellWithIdentifier("CellIdentifier", forIndexPath: indexPath) as! CustomCell 
    cell.yourLabel.textYouWant 
let yourViewController = storyboard?.instantiateViewControllerWithIdentifier("ViewController") as! ViewController 
    navigationController?.pushViewController(yourViewController, animated: true) 

}
