ios - 如何将 json 数据传递给可折叠标题 TableView Controller

Question

我试了很多次都没用。

错误:

/Users/admin/Desktop/Bkk 2/bkk/OfferDetailViewController.swift:93:55: Cannot convert value of type '[Deal]' to expected argument type '[String]'

代码:

var deals = [Deal]()

var sections = [Section]()


 sections = [
        Section(name: "Select from option", items:deals),
        Section(name: "merchant Details", items: [ForyouString, "iPad Air 2", "iPad mini 4", "Accessories"]),
        Section(name: "How to use deals", items: ["iPhone 6s", "iPhone 6", "iPhone SE", "Accessories"]),
        Section(name: "things to remember", items: ["exchange for cash not allowed"]),
        Section(name: "Cancelation policy", items: ["Once bought cannot exchange"]),
        Section(name: "what you get", items: ["Capacity buliding courses"])
    ]
 func parseDeals(data: NSData) -> [Deal]{
    var deals = [Deal]()

    do{
        let jsonresult = try JSONSerialization.jsonObject(with: data as Data, options: .mutableContainers) as? NSDictionary

        let jsondeals = jsonresult?["deals"] as! [AnyObject]
        for jsondeal in jsondeals{
            let deal = Deal()
            deal.deals_name = jsondeal["deals_name"] as! String
            deal.image_url = jsondeal["image_url"] as! String
            deal.actual_price = jsondeal["actual_price"] as! String
            deal.discounted_price = jsondeal["discounted_price"] as! String
            deal.discounted_percentage = jsondeal["discounted_percentage"] as! String
            deal.max_purchase_per_customer = jsondeal["max_purchase_per_customer"] as! String
            deal.qty_available = jsondeal["qty_available"] as! String
            deal.valid_from = jsondeal["valid_from"] as! String
            deal.valid_to = jsondeal["valid_to"] as! String
            deals.append(deal)

        }
                }
    catch{
        print(error)

    }
    return deals
}


func back(_ sender: Any) {
    self.dismiss(animated: true, completion: nil)
}

func buttonClicked(){

    print("button Clicked")

}
func showLocalError(errorMsg: String,title:String = "Oops!") {
    let appearance = SCLAlertView.SCLAppearance(
        showCloseButton: true
    )
    let alertView = SCLAlertView(appearance: appearance)
    alertView.showWarning(title, subTitle: errorMsg)
}


 func numberOfSections(in tableView: UITableView) -> Int {
    return sections.count
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return sections[section].items.count
}

// 
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as UITableViewCell? ?? UITableViewCell(style: .default, reuseIdentifier: "cell")

    cell.textLabel?.text = sections[(indexPath as NSIndexPath).section].items[(indexPath as NSIndexPath).row]
    return cell
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return sections[(indexPath as NSIndexPath).section].collapsed! ? 0 : 44.0
}

它在部分显示错误，当我传递交易时它显示错误，我找不到我做错的地方，我需要如何在部分传递交易数组。

错误信息很清楚:

在行中

Section(name: "Select from option", items:deals)

您传递的是 Deal 对象数组作为第二个参数，而不是预期的 String 数组，Section 初始值设定项是

init(name: String, items: [String])
