将嵌套的JSON数据列入表视图
我有一个复杂的嵌套JSON数据，如下所示：

我想获取具有“day_name”的“day”，然后相应地列出“例程”列表，如下图所示：
我已经制作了表格视图单元格设计并链接了所有属性，而且我已经制作了如下所示的结构：
我陷入了最后一个叫做（cellForRowAt）的函数
更新
我使用以下函数下载了我的JSON数据：
var dataRoutine = [RoutineDataModel]()
func downloadJsonData(completed : @escaping ()->()){
guard let url = URL(string: "http://www.swipecrafts.com/class/routine")else {return}
var request = URLRequest.init(url: url)
request.addValue("cf7ab8c9d4efae82b575eabd6bec76cbb86c6108391e036387f3dd5356a582171519367747000", forHTTPHeaderField: "api_key")
request.httpMethod = "POST"
request.httpBody = httpBodyy.data(using: .utf8)
URLSession.shared.dataTask(with: request) { (data, response, error) in
if let httpResponse = response as? HTTPURLResponse {
let statuscode = httpResponse.statusCode
if statuscode == 404{
self.displayMessage(userMessage: "Sorry! No Routine Found")
}else{
if error == nil{
do{
self.dataRoutine = try JSONDecoder().decode([RoutineDataModel].self, from: data!)
DispatchQueue.main.async {
completed()
print(self.dataRoutine.count)
}
}catch{
print(error)
}
}
}
}
}.resume()
}

对于此输出，您应该使用Headerview创建分段表视图。
实施如下的委托方法。
func numberOfSections(in tableView: UITableView) -> Int {
return arrDayDataModel.count //In your case, this is the array of day from Section Data Model
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let dayModel = arrDayDataModel[section]
return dayModel.routine.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell") as! CustomCell
let dayModel = arrDayDataModel[indexPath.section]
let routineDayModel = dayModel.routine[indexPath.row]
//Your Code goes here
cell.textLabel.text = routineDayModel.teacher
return cell
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 50
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 50))
headerView.backgroundColor = UIColor.lightGray
let lblTemp = UILabel(frame: headerView.bounds)
let dayModel = arrDayDataModel[indexPath.section] //Your FinalRouteDataModel
lblTemp.text = dayModel.day_name
headerView.addSubview(lblTemp)
return headerView
}
FYI。代码将根据您的实际要求进行更改，概念将在此处相同。
此处CustomCell是您的自定义表格视图单元格，如有任何疑问，请与我们联系。
