的UITableViewCell是空当的tableview滚动上攻

首先图像时，我不滚动的tableView

MY子项目是显示的UITableViewCell是空当的tableview滚动上攻

第二次图像当我滚动表查看

项

MY子项都是空白

我CellFor行代码是

var aryDictData = [[String:AnyObject]]() 

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 

     var aryOptionName = [String]() 
     var strOptionName = String() 

     var cell = DeliveryTableViewCell() 
     cell = tableView.dequeueReusableCell(withIdentifier: "DeliveryTableViewCell") as! DeliveryTableViewCell 
     cell.selectionStyle = .none 

     let productPrice = userDefault.object(forKey: ProductDesConstantNames.KAryStorePrices) as! [String] 

     if indexPath.section == 0{ 
      if indexPath.row < (aryDictData[0]["storeName"]!).count{ 

       cell.lblItemName.text = ((aryDictData[0]["storeName"]! as AnyObject)[indexPath.row] as! String) 

       cell.lblPrice.text = "$\(String(((Double(productPrice[indexPath.row])! + grandTotalProductPrice[indexPath.row]) * Double(numQuntity))))" 

       cell.lblItemQuantity.text = "\(numQuntity)x" 
       cell.lblItemQuantity.textColor = UIColor.init(red: 41/255, green: 144/255, blue: 85/255, alpha: 1.0) 

       let data = aryPreviewOrder[indexPath.row] as! [[String:AnyObject]] 
       print(data) 

       for i in 0..<((aryDictData[0]["options"]! as AnyObject)[indexPath.row]! as AnyObject).count { 
        let optionName = ((((aryDictData[0]["options"]! as AnyObject)[indexPath.row]! as AnyObject)[i] as AnyObject)["option_name"] as! String) 
        let prices = ((((aryDictData[0]["options"]! as AnyObject)[indexPath.row]! as AnyObject)[i] as AnyObject)["price"] as! String) 

        aryOptionName.append("\(optionName) ($\(prices))") 
        //     aryOptionPrices.append("($\(prices))") 

        strOptionName = aryOptionName.joined(separator: "\n") 
        //     strOptionPrice = aryOptionPrices.joined(separator: "\n") 
       } 
       cell.lblOptionNames.text = strOptionName 
       }    
      } 
    } 
    return cell 
}

请添加代码在你cellforrow – KavyaKavita

，我就迅速3 – Prototype

工作是你确保你能获得在'strOptionName'每一次数据？，写cell.layoutIfNeeded（），之后cell.lblOptionNames.text = strOptionName并在该行之前 –

尽量避免for循环中的行中的单元格，同时建立数据源，您可以创建这些选项名称并使用某个键将其存储在数组中，然后每次在cellforrow中重用该键，而不是再次创建n。

for i in 0..<((aryDictData[0]["options"]! as AnyObject)[indexPath.row]! as AnyObject).count { 
    let optionName = ((((aryDictData[0]["options"]! as AnyObject) 
    [indexPath.row]! as AnyObject)[i] as AnyObject)["option_name"] as! 
    String) 
    let prices = ((((aryDictData[0]["options"]! as AnyObject) 
    [indexPath.row]! as AnyObject)[i] as AnyObject)["price"] as! String) 
    aryOptionName.append("\(optionName) ($\(prices))") 
    } 
    strOptionName = aryOptionName.joined(separator: "\n") 

    cell.lblOptionNames.text = strOptionName
