Question

我从一个url抓取数据，这是一个PHP脚本，它是从MySQL数据库编码我的数据的JSON。我的数据进入我的应用程序，我知道如何解析它，但我不确定如何将我的数据放在我的集合视图中的每个项目的textField.stringvalue中。我在这个主题上发现的大部分信息都是针对iOS的，我正在为OS X制作应用程序。

ViewController.swift

import Cocoa

class ViewController: NSViewController  {

@IBOutlet weak var collectionView: NSCollectionView!

var productCategories: [ProductCategory]?

let baseURL = "http://myURL"

override func viewDidLoad() {
    super.viewDidLoad()

    getJSON()
    self.collectionView.reloadData()

}

func getJSON(){

    let url = NSURL(string: baseURL)
    let request = NSURLRequest(url: url! as URL)
    let session = URLSession(configuration: URLSessionConfiguration.default)
    let task = session.dataTask(with: request as URLRequest) { (data,response,error) -> Void in

        if error == nil {

            let swiftyJSON = JSON(data:data!)
            print(swiftyJSON)
            let product = swiftyJSON[].arrayValue

            for name in product{

                let names = name["product_name"].stringValue
               print(names)
            }


        } else{
            print("Error")
        }
    }
    task.resume()
}


override var representedObject: Any? {
    didSet {
    // Update the view, if already loaded.
    }
}


}

extension ViewController: NSCollectionViewDataSource{

func collectionView(_ collectionView: NSCollectionView, numberOfItemsInSection section: Int) -> Int {
    if let count = productCategories?.count {
        return count
    }
    return 0
}

func collectionView(_ collectionView: NSCollectionView, itemForRepresentedObjectAt indexPath: IndexPath) -> NSCollectionViewItem {



    let item = collectionView.makeItem(withIdentifier: "ImageCollectionViewItem", for: indexPath)

    item.textField?.stringValue = Product.product_name

    return item
}
}

Model.swift

import Foundation

class ProductCategory: NSObject {

var name: String?
var productss: [Product]?
var type: String?
}



class Product: NSObject {

var id: NSNumber?
var product_name: String?
var product_price: NSNumber?
var product_description: String?
var product_image: String?
var product_download: String?
var product_video: String?
var product_featured: Int?
}
