Question

我有一个数组，我循环并将值传递给我的表格视图单元格标签。但是当我传递值时，标签只显示数组的最后一个值。我希望它显示来自数组的所有项目。我怎么能证明这一点？

let addonDescrip = ItemDataSource.sharedInstance.items[indexPath.row].addonDescp
print(addonDescrip)
for items in addonDescrip{
    print(items)
    cell.descriptionLbl.text = items
    print(cell.descriptionLbl.text)
}

我希望它按以下顺序显示项目：

item1,
item2,
item4

我们如何在表格视图单元格标签中显示这样的内容？我的表视图委托，

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

         return ItemDataSource.sharedInstance.items.count
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 72
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


    let cell = cartTableView.dequeueReusableCell(withIdentifier: "cartCell", for: indexPath) as! CartTableViewCell

    cell.dishTitleLbl.text = ItemDataSource.sharedInstance.items[indexPath.row].itemName!
    cell.priceLbl.text = ItemDataSource.sharedInstance.items[indexPath.row].totalPrice!
    print(cell.priceLbl.text!)

        let addonDescrip = ItemDataSource.sharedInstance.items[indexPath.row].addonDescp
        print(addonDescrip)
        for items in addonDescrip{
            print(items)
            cell.descriptionLbl.text = items
            print(cell.descriptionLbl.text)
        }

    cell.quantityLbl.text = "1"//String(ItemDataSource.sharedInstance.items[indexPath.row].cartItem)
    itemname = cell.dishTitleLbl.text!
    itemDescription = cell.descriptionLbl.text!
    itemprice = cell.priceLbl.text!
    itemID = ItemDataSource.sharedInstance.items[indexPath.row].itemID!
    cell.deleteBtn.tag = indexPath.row
    cell.addBtn.tag = indexPath.row
    cell.minusBtn.tag = indexPath.row
    cell.deleteBtn.addTarget(self, action: #selector(crossBtnTapped), for: .touchUpInside)
    cell.quantityLbl.layer.cornerRadius = 3
    cell.quantityLbl.layer.borderColor = #colorLiteral(red: 0.501960814, green: 0.501960814, blue: 0.501960814, alpha: 1)
    cell.quantityLbl.layer.borderWidth = 1.5
    cell.selectionStyle = .none
    cell.delegate = self
    return cell
}

如果要在一个标签中显示所有项目，请按照

添加字符串

    for (index,item) in addonDescrip.enumerated() {
        print(items)
        if index == 0 {
           cell.descriptionLbl.text = item
        } else {
           cell.descriptionLbl.text = cell.descriptionLbl.text + "," + item
        }

        print(cell.descriptionLbl.text)
    }

或

cell.descriptionLbl.text = addonDescrip.joined(separator: ",")
