我有以下類模型的項目。我在部分中顯示itemsName,itemprice。並根據索引在單元格中添加Addname和AdddonPrice ..節的數量和單元的數量從類模式正確地到來。節數據也工作正常。問題是將插件數據顯示到customTableCell中。從類模型錯誤中填充tableView單元格中的項?
class Cart{
var itemID:AnyObject?
var itemName:AnyObject?
var itemPrice:AnyObject?
var cartAddon:[AnyObject?]
init(itemID:AnyObject?,itemName:AnyObject?,itemPrice:AnyObject?,cartAddon:[AnyObject?]){
self.itemID = itemID
self.itemName = itemName
self.itemPrice = itemPrice
self.cartAddon = cartAddon
}
}
class CartAddon {
var addonID:Int?
var addonName:String?
var addonPrice:Double?
init(addonID:Int?,addonName:String?, addonPrice:Double?){
self.addonID = addonID
self.addonName = addonName
self.addonPrice = addonPrice
}
}
泰伯維代碼
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return cartArray.count
}
func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 50
}
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let header = tableView.dequeueReusableCellWithIdentifier("cartheadercell") as! cartHeaderCell
header.ItemnameLbl.text = cartArray[section].itemName as? String
header.ItemPriceLbl.text = (cartArray[section].itemPrice as! String)
return header
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cartArray[section].cartAddon.count
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 30
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cartcell", forIndexPath: indexPath) as! AddonCell
//error in this part
let cart: Cart = cartArray[indexPath.row].cartAddon[indexPath.row]
if let name = cart.cartAddon[indexPath.row]!["AddonName"]{
cell.AddonNameLbl.text = (name as! String)
}
cell.AddonPriceLbl.text = "£ 0.0"
return cell
}
的數據以這種形式,我一定要顯示未來是:
Optional(9 Inch Thin & Crispy Margarita)
Optional(£3.40)
Optional(1749)
[Optional(Chicos_Pizza.CartAddon), Optional(Chicos_Pizza.CartAddon), Optional(Chicos_Pizza.CartAddon), Optional(Chicos_Pizza.CartAddon)]
只需添加'!'解開這些值以擺脫可選 – Dravidian
那不是問題..仔細查看數據。我只向你發送我正在保存到類模型中的數組格式類型。現在從那我需要顯示在給定的單元格。可選的。我知道要處理它。 @Dravidian –
只是檢查@NDoc –
