ios - 如何在不在 UITableView iOS Swift 中创建多个自定义单元格的情况下加载数组值 int 单元格？

Question

我在表格 View 中有多个标签。为标签左侧创建了一个数组。现在我正在尝试从每个标签的数组模型加载数据。但它说索引超出范围，因为它的模型数组索引为 0。

这是我的模型:

 class PrItemDetailModel {

var Material: String?
var Description: String?
var FixedVendor: String?
var VendorName: String?
var PurchOrg: String?
var PurchGroup: String?
var qtyUoM: String?
var valuationPrice: String?
var TotalValue: String?
var DeliveryDate: String?
var MatGrp: String?
var Plant: String?
var StorageLocation: String?
var ReqTrack: String?
var AAC: String?
var ItemCategory: String?
var GLAccount: String?
var CostCenter: String?
var Order: String?
var WBS: String?
var ProfitCenter: String?


init(Material: String?, Description: String?, FixedVendor: String?, VendorName:String?, PurchOrg: String?, PurchGroup: String?, qtyUoM: String?, valuationPrice: String?, TotalValue: String?, DeliveryDate: String?, MatGrp: String?, Plant: String?, StorageLocation: String?, ReqTrack: String?, AAC: String?, ItemCategory: String?, GLAccount: String?, CostCenter: String?, Order: String?, WBS: String?, ProfitCenter: String?){

    self.Material = Material
    self.Description = Description
    self.FixedVendor = FixedVendor
    self.VendorName = VendorName
    self.PurchOrg = PurchOrg
    self.PurchGroup = PurchGroup
    self.qtyUoM = qtyUoM
    self.valuationPrice = valuationPrice
    self.TotalValue = TotalValue
    self.DeliveryDate = DeliveryDate
    self.MatGrp = MatGrp
    self.Plant = Plant
    self.StorageLocation = StorageLocation
    self.ReqTrack = ReqTrack
    self.AAC = AAC
    self.ItemCategory = ItemCategory
    self.GLAccount = GLAccount
    self.CostCenter = CostCenter
    self.Order = Order
    self.WBS = WBS
    self.ProfitCenter = ProfitCenter

    }

 }

这是为标签创建的数组:

   var PrItemTitleLblArray = ["Material#", "Description", "Fixed Vendor#","Vendor Name", "Purch Org", "Purch Group", "Qty | UoM", "valuation Price", "Total Value", "Delivery Date", "Mat Grp", "Plant", "Storage Location", "Req Track#", "AAC", "Item Category", "G/L Account", "Cost Center", "Order", "WBS", "Profit Center"]

这是来自模型的数组:

  var prItemArray = [PrItemDetailModel(Material: "", Description: "Bottles", FixedVendor: "KP04", VendorName: "KP Suppliers", PurchOrg: "1000", PurchGroup: "002", qtyUoM: "40.000 EA", valuationPrice: "EUR 40.00", TotalValue: "EUR 1,600.00", DeliveryDate: "09/12/2014", MatGrp: "00807", Plant: "1100", StorageLocation: "", ReqTrack: "", AAC: "Cost Center", ItemCategory: "0", GLAccount: "000040000", CostCenter: "0000010000", Order: "", WBS: "0000000", ProfitCenter: "0000001402")]

这是我在 tableview 中使用的代码:

       let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! PrItemCellTableViewCell

       cell.material.text = PrItemTitleLblArray[indexPath.row]
       cell.materialvalue = prItemArray[indexPath.row]

    return cell

这是我想要实现的屏幕截图:

这是我的 json 响应:

 "results": [
  {

   "PoDocNo": "4500022400",
   "Item": "00010",
   "Material": "RMECC_MOB1",
   "StorageLocation": "3001",
   "MatGroup": "00107",
   "Quantity": "2.000",
    "OrderUnit": "KG",
   "NetPrice": "1000.000",
   "UnitofPrice": "1.000",
   "ItemCat": "0",
   "Requistor": ""
   },
  {

  "PoDocNo": "4500022400",
  "Item": "00020",
  "Material": "RMECC_MOB1",
  "StorageLocation": "3001",
  "MatGroup": "00107",
  "Quantity": "2.000",
   "OrderUnit": "KG",
  "NetPrice": "1000.000",
  "UnitofPrice": "1.000",
  "ItemCat": "0",
  "Requistor": ""
  }
  ] 

非常感谢任何帮助...

在下面检查我的简单更新答案 你能建议我在传递 json 时最好的方法吗

您可以创建结构来形成您需要的记录，如下所示，

    struct DemoItems {

        var key: String?
        var value: String?
    }

fileprivate var demoItems: [DemoItems]?

fileprivate func loadDemoItems() -> [DemoItems] {

        var tempItems = [DemoItems]()

        let item1 = DemoItems.init(key: "Material#", value: "")
        let item2 = DemoItems.init(key: "Description", value: "Bottles")
        let item3 = DemoItems.init(key: "Fixed Vendor#", value: "KP04")
        let item4 = DemoItems.init(key: "Vendor Name", value: "KP Suppliers")
        let item5 = DemoItems.init(key: "Purch Org", value: "1000")

        tempItems.append(item1)
        tempItems.append(item2)
        tempItems.append(item3)
        tempItems.append(item4)
        tempItems.append(item5)

        return tempItems
    }

在viewDidLoad之类的，

    demoItems = loadDemoItems()

    if let tempDemoItems = demoItems {

        print(tempDemoItems)
        print(tempDemoItems[0].key)
        print(tempDemoItems[0].value)
    }

输出:

[permisdesauver_dev.DemoItems(key: Optional("Material#"), value: Optional("")), permisdesauver_dev.DemoItems(key: Optional("Description"), value: Optional("Bottles")), permisdesauver_dev.DemoItems(key: Optional("Fixed Vendor#"), value: Optional("KP04")), permisdesauver_dev.DemoItems(key: Optional("Vendor Name"), value: Optional("KP Suppliers")), permisdesauver_dev.DemoItems(key: Optional("Purch Org"), value: Optional("1000"))]
Optional("Material#")
Optional("")

所以你的 cell.material.text = tempDemoItems[indexPath.row].key & cell.materialvalue.text = tempDemoItems[indexPath.row].value

希望对您有所帮助!
