我能够获取图片网址和其他详细信息的值，但在UITableview上显示时，它不会显示在正确的索引上，例如

Tableview索引1 - 它显示产品名称和prod.price但图片网址显示在下一个tableview索引中，即-2

Tableview索引2 - 它显示第一个索引的图像网址为产品名称，价格为零

Tableview索引3 - 它显示产品名称和prod.price但图片网址显示在下一个tableview索引中，即-4

并继续这样......

这是我的代码

func parseJSONData(data: NSData) -> [ProductDetails] {
    var product_Detail = [ProductDetails]()
    do {
            let jsonResult = try     NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary

         let jsonProductDetails = jsonResult?["data"] as! [AnyObject]
     print("the json response is",jsonProductDetails)

        for jsonproductDetail in jsonProductDetails{
            let productDetail = ProductDetails()

            productDetail.productAuthor = jsonproductDetail["first_name"]as! String
            productDetail.productPrice =  jsonproductDetail["prodprice"]as! Int


            product_Detail.append(productDetail)



           let jsonResult = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers) as? NSArray
           let jsonProductImageDetails = jsonproductDetail["images"] as! [AnyObject]
           print("the json response is",jsonProductImageDetails)

      //Where to make a loop to get the desired result 
          for jsonproductImage in jsonProductImageDetails{
               let product_Image = ProductDetails()
               product_Image.productImages = jsonproductImage["imagepath"] as! String
               product_Detail.append(product_Image)


           }

        }
    }
    catch {
        print (error)
    }
    self.parseJSONImage(data)
    return product_Detail

}

模型

class ProductDetails {
    var productAuthor: String!
    var productPrice: Int!
    var artImages: String!
}

显示单元格图像

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cellIdentifier = "Cell"
    let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! UserHomeScreenTableViewCell

    // Configure the cell...
    cell.artsAuthorName.text = globalArr[indexPath.row].productAuthor
    cell.priceLabel.text = "\(globalArr[indexPath.row].productPrice)"  //to convert string value to interger
    let productDetailsObject = globalArr[indexPath.row].artImages
    print("@@@@@@@@@@@@@@@@@",productDetailsObject)





    dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {

        if let url = NSURL(string: self.globalArr[indexPath.row].artImages.imagepath) {
            if let data = NSData(contentsOfURL: url) {
                if let image = UIImage(data: data) {
                    dispatch_async(dispatch_get_main_queue()) { () -> Void in
                        cell.artImageView.image = image
                    }
                }
            }
        }
    })

    return cell
}

Answer 1

模型类。

class ProductDetails {
    var productAuthor: String!
    var productPrice: Int!
    var artImages: [ArtImage]!
}

class ArtImage {
    var imagepath: String!
    var imgvideotype: Int!
}

我们会将ArtImage数组存储为ProductDetails的属性。 Simillarly你也可以为 videos 创建其他类所以你可以使用它如下。

let productDetailsObject = //value of your ProductDetails object
let imagePath = productDetailsObject.artImages[0].imagepath

重写该功能如下。

func parseJSONData(data: NSData) -> [ProductDetails] {
    var product_Detail = [ProductDetails]()


    do {
        let jsonResult = try     NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary

        let jsonProductDetails = jsonResult?["data"] as! [AnyObject]
        print("the json response is",jsonProductDetails)

        for jsonproductDetail in jsonProductDetails{
            let productDetail = ProductDetails()

            productDetail.productAuthor = jsonproductDetail["first_name"]as! String
            productDetail.productPrice =  jsonproductDetail["prodprice"]as! Int

            //we will fetch the images from first object, i.e. from the jsonproductDetail
            let jsonProductImageDetails = jsonproductDetail["images"] as! [AnyObject]
            var artImagesModelArray  = [ArtImage]()
            for image in jsonProductImageDetails {
                let artImage = ArtImage();
                artImage.imagepath = image["imagepath"] as! String
                artImage.imgvideotype = image["imgvideotype"] as! Int
                artImagesModelArray.append(artImage)
            }
            productDetail.artImages = artImagesModelArray;

            product_Detail.append(productDetail)
        }
    }
    catch {
        print (error)
    }
    return product_Detail
}

Answer 2

使用func parseJSONData（data：NSData）更改代码 - ＆gt; [产品详情] { var product_Detail = ProductDetails 做{ 让jsonResult =尝试NSJSONSerialization.JSONObjectWithData（数据，选项： NSJSONReadingOptions.MutableContainers）为？的NSDictionary

         let jsonProductDetails = jsonResult?["data"] as! [AnyObject]

        for jsonproductDetail in jsonProductDetails {
            let productDetail = ProductDetails()`
           let jsonProductImageDetails = jsonProductDetails["images"] as! [AnyObject]

            productDetail.productAuthor = jsonproductDetail["first_name"]as! String
            product.Detail.productImages = jsonProductImageDetails["imagepath"] as! String
            productDetail.productPrice =  jsonproductDetail["prodprice"]as! Int
            product_Detail.append(productDetail)
        }
    }
    catch {
        print (error)
    }
    self.parseJSONImage(data)
    return product_Detail }

解析后，URL不会出现在UITableview的正确索引中
