实现自定义搜索栏，使用文本字段作为输入来搜索文本以及如何在iOS Swift中调用Search api

Question

我已经使用文本字段搜索文本，并且可以很好地处理虚拟硬编码数据。不知道如何从API解析搜索数据。我的json文件链接为：https://api.myjson.com/bins/x8a4x，其中包含搜索的主体参数。我错了，请纠正我。并已在文本字段下方使用tableview来显示搜索数据

我的搜索页面控制器文件：-

class SearchPageController: UIViewController {

    @IBOutlet weak var searchTxtBar: UITextField!
    @IBOutlet weak var searchTblView: UITableView!

    @IBOutlet weak var searchMessage: UIView!

    var CatStoreData:[String] = Array()
    var filteredData:[String] = Array()

    var searchData = [ModelSearched]()

    var search = "M"

    override func viewDidLoad() {
        super.viewDidLoad()

        self.hideKeyboardWhenTappedAround()
        self.searchMessage.isHidden = true

        // Do any additional setup after loading the view.
        searchTxtBar.delegate = self

        //append data to catstoredata array
        CatStoreData.append("costco.com.au")
        CatStoreData.append("au.kogan.com")
        CatStoreData.append("rebelsport.com.au")
        CatStoreData.append("ebgames.com.au")
        CatStoreData.append("computeralliance.com.au")
        CatStoreData.append("harveynorman-com-au")
        CatStoreData.append("binglee.com.au")
        CatStoreData.append("iwantthatflight.com.au")
        CatStoreData.append("mobileciti.com.au")
        CatStoreData.append("Electronics and Gadgets")
        CatStoreData.append("Baby Care")
        CatStoreData.append("Computers")
        CatStoreData.append("Computers and Laptops")
        CatStoreData.append("Entertainment")
        CatStoreData.append("Eyewear")
        CatStoreData.append("Flights")
        CatStoreData.append("Home & Kitchen")

        for data in CatStoreData {
            filteredData.append(data)
        }
        searchTxtBar.addTarget(self, action: #selector(searchRecords(_ :)), for: .editingChanged)
    }

    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }

    @objc func searchRecords(_ textfield: UITextField) {

//        self.CatStoreData.removeAll()
        self.CatStoreData.removeAll()
        if searchTxtBar.text?.count != 0 {
            for data in filteredData {

                if let dataToSearch = self.searchTxtBar.text {
                    let range = data.lowercased().range(of: dataToSearch, options: .caseInsensitive, range: nil, locale: nil)
                    if range != nil {
                        CatStoreData.append(data)
                    }
                }
            }
        }else {

                CatStoreData.append(data)
            }

        searchTblView.reloadData()
