ios - 值存储在数组中但无法访问？

Question

我已经对如下所示的 Web api 进行了排序，并将键“attributevalue”的值存储在数组中，但在访问它时没有显示任何建议

{
  "responsemsg": "successfull",
  "responsecode": "200",
  "data": {
          "sku": "arv-95x103535",
           "description": "<p>watercolor on paper</p>\r\n",
           "shortdescription": "",
"prodattribute": [
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,
    "colorimgpath": "",
    "attributevalue": "10",
    "lablename": " Height Inch",
    "fk_elementdetailid": 12,
    "IsRequired": true
  },
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,
    "colorimgpath": "",
    "attributevalue": "9.5",
    "lablename": " Width Inch",
    "fk_elementdetailid": 13,
    "IsRequired": true
  },
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,
    "colorimgpath": "",
    "attributevalue": "N.A",
    "lablename": " Year ",
    "fk_elementdetailid": 15,
    "IsRequired": true
  },
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,
    "colorimgpath": "",
    "attributevalue": "Water color on paper",
    "lablename": " Medium ",
    "fk_elementdetailid": 16,
    "IsRequired": true
  },
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,
    "colorimgpath": "",
    "attributevalue": "right bottom",
    "lablename": " Signature Position ",
    "fk_elementdetailid": 17,
    "IsRequired": true
  },
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,
    "colorimgpath": "",
    "attributevalue": "Canvas",
    "lablename": " Surface ",
    "fk_elementdetailid": 19,
    "IsRequired": true
  }
]

这是我的解析代码

   let jsonProductAttributes = jsonResult!["data"]!["prodattribute"] as! [AnyObject]
        print("The product Arrtibutes are",jsonProductAttributes)
        var artAttributesArry = [details]()
    for attri in jsonProductAttributes {
        let artDetails = details();
        artDetails.values = attri["attributevalue"]as! String
        artAttributesArry.append(artDetails)
   print("The attributed values are ",attri["attributevalue"]as! String)

    }

这是我的模型类

 class DetailProduct {
var attributes: [details]!

}

class details {
var values: String!
}

如果代码有任何更改或更改，任何建议都会非常有帮助

谢谢

最后您的 JSON 丢失了:

 }
}

我使用 Alamofire 和 SwiftyJSON 测试了以下内容，有效:

import Foundation
import Alamofire
import SwiftyJSON

class APIWrapper {

    func getJSON() {

        print("Making request");
        Alamofire.request(.GET, "http://localhost:8000/swift") .responseJSON {
            (request, response, result) -> Void in

            if let value = result.value {
                let json = JSON(value)
                self.parseJSON(json)
            }
        }

    }

    func parseJSON(json: JSON) {

        for result in json["data"]["prodattribute"].arrayValue {
            print(result["attributevalue"].stringValue)
        }
    }
}

使用以下 JSON:

{
  "responsemsg": "successfull",
  "responsecode": "200",
  "data": {
          "sku": "arv-95x103535",
           "description": "<p>watercolor on paper</p>\r\n",
           "shortdescription": "",
"prodattribute": [
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,
    "colorimgpath": "",
    "attributevalue": "10",
    "lablename": " Height Inch",
    "fk_elementdetailid": 12,
    "IsRequired": true
  },
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,
    "colorimgpath": "",
    "attributevalue": "9.5",
    "lablename": " Width Inch",
    "fk_elementdetailid": 13,
    "IsRequired": true
  },
  {
    "attrkeyvalue": "",
    "fk_CategoryId": 78,

  {

    "attributevalue": "Water color on paper",
    "lablename": " Medium ",

  }
]
}
