我嘗試了很多次,但它不起作用。如何將json數據傳遞到collapsableheader tableview控制器
錯誤:
/Users/admin/Desktop/Bkk 2/bkk/OfferDetailViewController.swift:93:55: Cannot convert value of type '[Deal]' to expected argument type '[String]'
代碼:
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"])
]

它顯示了錯誤的部分,當我通過交易,它顯示的錯誤,我找不到在哪裏我沒有錯,我需要如何通過交易數組。
你似乎使用Swift 3,避免使用所以避免'NSDictionary'和其他「太Objective-C」的東西。 – Larme
'cell.textLabel?.text = sections [(indexPath as NSIndexPath).section] .items [(indexPath as NSIndexPath).row]'如果有'section == 0',那麼你有一個Deals對象數組,不是一個字符串數組。 – Larme
它顯示部分= [ 部分(名稱:「從選項中選擇,項目:交易)錯誤,當我在這裏通過交易時,它顯示錯誤 – udaykumar40
