Question

我是iOS Swift的新手。在这里，我有一个jsonResponse，它来自我的Web服务。现在，我想解析此响应到我的数组。这是我的模型类代码。

 struct OrderItem:Codable{
let purchaseId : Int
let purchasedDate: String
let purchasedStatus: Int
let purchasedItems: [String]

}

这是我来自网络服务的回复。

    URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { (data, response, error)-> Void in
            do{
//                let data = try JSONSerialization.jsonObject(with: data!, options: []) as! Array<Any>
                let decoder = JSONDecoder()
                self.orderMenu = try! decoder.decode([OrderItem].self, from: data!)
                print("===122===",self.orderMenu)
            }catch{
                print("ERROR")
            }
            DispatchQueue.main.async {
                self.MytableView.reloadData()
            }
        }).resume()

这是我的jsonResponse

[
{
    "purchaseId": 19,
    "purchasedDate": "2018-07-27 23:48",
    "purchasedStatus": 0,
    "purchasedItems": [
        {
            "purchasedItemsId": 72,
            "purchasedCount": 2,
            "purchasedPrice": 34,
            "purchasedGST": 3,
            "itemDescription": "abcd2",
            "itemCategoryDescription": "Cloths_Type_6",
        },
        {
            "purchasedItemsId": 73,
            "purchasedCount": 3,
            "purchasedPrice": 44,
            "purchasedGST": 9.1,
            "itemDescription": "Item2",
            "itemCategoryDescription": "Flags",
        },
        {
            "purchasedItemsId": 74,
            "purchasedCount": 4,
            "purchasedPrice": 123,
            "purchasedGST": 3,
            "itemDescription": "Item3",
            "itemCategoryDescription": "Food",
         },
        {
            "purchasedItemsId": 75,
            "purchasedCount": 5,
            "purchasedPrice": 42,
            "purchasedGST": 9.1,
            "itemDescription": "Item4",
            "itemCategoryDescription": "Flags",
        }
    ]
}

]

有人请给我一个解决方案，任何解决方案表示赞赏。

purchasedItems是一个字典数组，对于字典，您必须创建另一个结构

struct OrderItem : Decodable {
   let purchaseId : Int
   let purchasedDate: String
   let purchasedStatus: Int
   let purchasedItems: [PurchasedItem]
}

struct PurchasedItem : Decodable {
   let purchasedItemsId, purchasedCount, purchasedPrice : Int
   let purchasedGST : Double
   let itemDescription, itemCategoryDescription : String
}

然后您可以使用

打印itemDescription中的orderMenu

for order in orderMenu {
    for item in order.purchasedItems {
      print(item.itemDescription)
    }
}

然后-再次-始终在catch块中打印错误实例

} catch {
    print(error)
}
