TableView Json数组

Question

       {
         "YASSINIRLA" : "True",
          "KARBON" : "98",
          "GRUP" : "Orta Boy",
          "INDIRIMORANI" : "0",
          "KLIMA_TR" : "Var",
          "KREDI_FIYAT" : "107",
           "SIRANO" : "1",
          "YAKIT_EN" : "Diesel",

        }

您好。我解决了这个问题但是时间太长了。我为他们创建了一个数组。我也在表格视图中展示了它。我怎样才能缩短它？对不起我的英语不好。感谢。

 dizi1.append(arac["YASSINIRLA"].string!)
 dizi2.append(arac["KARBON"].string!)
 dizi3.append(arac["INDIRIMORANI"].string!)
 dizi4.append(arac["KLIMA_TR"].string!)
 dizi5.append(arac["KREDI_FIYAT"].string!)

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

    return diziAracModelii.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "sonAracListelee") as! sonAracListeleViewCell

    cell.lblAracAdi1.text = dizi1[indexPath.row]
    cell.lblAracAdi2.text = dizi2[indexPath.row]
    cell.lblAracAdi3.text = dizi3[indexPath.row]
    cell.lblAracAdi4.text = dizi4[indexPath.row]
    cell.lblAracAdi5.text = dizi5[indexPath.row]


    return cell
}

更容易做的是创建一个结构模型，在其中声明变量。然后，您可以创建一个启动器函数，您可以使用json对象中的数据启动变量。我建议在执行此操作时使用SwiftyJSON。

如果让我们在init函数中确保检查对象是否包含任何值。

struct CustomModel {
    public private(set) var yassinirla: String?
    public private(set) var karbon: String?
    public private(set) var indirimorani: String?
    public private(set) var klimaTr: String?
    public private(set) var krediFiyat: String?

    init(arac: JSON) {
         if let yassinirla = arac["YASSINIRLA"].string { 
             self.yassinirla = yassinirla
         }

         if let karbon = arac["KARBON"].string { 
             self.karbon = karbon
         }

         if let indirimorani = arac["INDIRIMORANI"].string { 
             self.indirimorani = indirimorani
         }

         if let klimaTr = arac["KLIMA_TR"].string else { 
             self.klimaTr = klima_tr
         }

         if let krediFiyat = arac["KREDI_FIYAT"].string else {
             self.krediFiyat = krediFiyat
         }
    }
}

在标题中，您可以将数组diziAracModelii声明为[CustomModel]，这样您就不必为每个字符串使用单独的数组。这只是不好的做法。您可以使用单个数组处理此问题。

diziAracModelii: [CustomModel] = [CustomModel]()

func grabJson() {
    //...Download the json into a json constant

    //Send in the jsonobject in the CustomModel
    let newObject = CustomModel(arac: json)

    //Append to your string and make sure to reload the tableView data.
    diziAracModelii.append(newObject)
    self.yourTableView.reloadData()

}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return diziAracModelii.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    guard let cell = tableView.dequeueReusableCell(withIdentifier: "sonAracListelee") as sonAracListeleViewCell else { return UITableViewCell() }

    cell.lblAracAdi1.text = diziAracModelii[indexPath.row].yassinirla
    cell.lblAracAdi2.text = diziAracModelii[indexPath.row].karbon
    cell.lblAracAdi3.text = diziAracModelii[indexPath.row].indirimorani
    cell.lblAracAdi4.text = diziAracModelii[indexPath.row].klimaTr
    cell.lblAracAdi5.text = diziAracModelii[indexPath.row].krediFiyat


    return cell
}
