我尝试过使用类别->子类别获得结果，但是当我尝试使用子子类别时，我失败了。
`func numberOfSections（在tableView中：UITableView）-> Int { 返回getPriceList.count } func tableView（_ tableView：UITableView，numberOfRowsInSection部分：Int）-> Int { 如果getPriceList [section] .isOpened == true { 返回getPriceList [section] .subService！.count + 1 }其他{ 返回1 } }
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let subCategoryIndex = indexPath.row - 1
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: CELL_ID.JF_PRICE_LIST_CELL, for: indexPath) as! PriceListCell
cell.textLabel?.text = getPriceList[indexPath.section].serviceName
cell.backgroundColor = #colorLiteral(red: 0.2613176107, green: 0.2559443712, blue: 0.2659199238, alpha: 1)
return cell
}else{
let cell = tableView.dequeueReusableCell(withIdentifier: CELL_ID.JF_PRICE_LIST_CELL, for: indexPath) as! PriceListCell
cell.textLabel?.text = getPriceList[indexPath.section].subService?[subCategoryIndex].subServiceName
cell.backgroundColor = #colorLiteral(red: 0.2790801227, green: 0.6332188845, blue: 0.4609255791, alpha: 0.8018487966)
return cell
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if indexPath.row == 0{
if getPriceList[indexPath.section].isOpened == true{
getPriceList[indexPath.section].isOpened = false
let sections = IndexSet(integer: indexPath.section)
tableView.reloadSections(sections, with: .fade)
}else{
getPriceList[indexPath.section].isOpened = true
let sections = IndexSet(integer: indexPath.section)
tableView.reloadSections(sections, with: .fade)
