    var cover_image_url = ""

        tableview.delegate = self
        tableview.dataSource = self
        tableview.rowHeight = 300

        return tableview
    }()

    // 數(shù)據(jù)源
    var dataArray = [ItemsModel]()

    override func viewDidLoad() {
        super.viewDidLoad()

        self.navigationItem.title = "SwiftyJSON_HandyJson的使用"

        self.view.addSubview(gifttableview)
        self.AlamofireGetRequest()
        //self.AlamofirePostRequest()
        //注冊cell
        gifttableview.register(SamTableViewCell.self)
    }

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

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        return cell
    }

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
         print(indexPath.row)
    }
}

extension SwiftyJSON_HandyJson_VC{

    func AlamofireGetRequest() {

        NetworkManager.NetWorkRequest(.getPhotoList, completion: { (JSOnDictory) -> (Void) in//JSOnDictory 是Json類型

            print(errorStr)
