快速使用fscalendar从API响应中获取事件的值

如何解决快速使用fscalendar从API响应中获取事件的值

我有fscalendar，它显示了从API响应预订的事件列表。 Json数据如下：

{
    "status": 200,"schedule_data": {
        "2020_08_16_1597485600": {
            "schedule_date": "2020-08-16","nanny_id": 2,"shift_start": "06:00","shift_end": "13:00","schedule_id": 112
        },"2020_08_16": {
            "schedule_date": "2020-08-16","shift_start": "","shift_end": "","schedule_id": 0
        },"2020_08_17_1597485600": {
            "schedule_date": "2020-08-17","shift_end": "22:00","schedule_id": 113
        },"2020_08_17": {
            "schedule_date": "2020-08-17","2020_08_18": {
            "schedule_date": "2020-08-18","2020_08_19": {
            "schedule_date": "2020-08-19","2020_08_20": {
            "schedule_date": "2020-08-20","2020_08_21": {
            "schedule_date": "2020-08-21","2020_08_22": {
            "schedule_date": "2020-08-22","2020_08_23": {
            "schedule_date": "2020-08-23","2020_08_24": {
            "schedule_date": "2020-08-24","2020_08_25": {
            "schedule_date": "2020-08-25","2020_08_26": {
            "schedule_date": "2020-08-26","2020_08_27": {
            "schedule_date": "2020-08-27","2020_08_28": {
            "schedule_date": "2020-08-28","2020_08_29": {
            "schedule_date": "2020-08-29","2020_08_30": {
            "schedule_date": "2020-08-30","2020_08_31": {
            "schedule_date": "2020-08-31","schedule_id": 0
        }
    }
}

我已经根据schedule_id从这个api响应中获取了不等于零的事件，这样我有两个事件（16-8-2020,17-8-2020）并将它们存储在使用fscalendar委托方法在fscalendar上显示事件，如下所示：

func日历（_日历：FSCalendar，didSelect日期：日期，在月份位置：FSCalendarMonthPosition）{

    self.scheduleview.isHidden = false
    self.mainview.addSubview(self.scheduleview)
    self.todaydateLbl.text = "Availablity on " + self.formatter.string(from: date)
    self.selectdate = self.formatter.string(from: date)
    
      print("calendar did select date \(self.formatter.string(from: date))")
         if monthPosition == .previous || monthPosition == .next {
             calendar.setCurrentPage(date,animated: true)
         }

} 我有一个视图，单击日期即显示为scheduleview。 如果事件已经存在，它将显示开始时间和结束时间值。 如何获取已经存在的事件的开始和结束时间。例如，当用户选择16-8-2020时，他应该能够看到现有事件的详细信息，该详细信息将通过API向他显示开始和结束时间响应。该怎么办？ json解析代码如下：

let decoder = JSONDecoder()
                      
                      do {
                          
                          let user = try decoder.decode(ScheduleListModel.self,from: response.data!)
                          self.listdata = user
                        
                        for schedule in self.listdata!.scheduleData {
                            if schedule.value.scheduleID != 0 {
                                self.eventsArray.append(schedule.value.scheduleDate!)
                            }
                        }
                        

                        print("eventsarray is",self.eventsArray)
                        
                        if self.eventsArray.count > 0
                        {
                            self.calendar.delegate = self
                            self.calendar.dataSource = self
                            self.calendar.reloadData()
                        }
                        

                         } catch {
                             debugPrint(error)
                      }

如何从这些可用数据中获取详细信息？

解决方法

您的API响应中有"schedule_date": "2020-08-31"，我假设您也保存在数据模型中。因此，当您从calendar(_ calendar: FSCalendar,didSelect date: Date方法中获取所选日期时，请将其转换为模型中保存的格式并过滤数据模型。

let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd"
let selectedDateString = formatter.string(from: date)

let selectedEvents = scheduleData.filter { ($0.value.scheduleId != 0) && ($0.value.scheduleDate == selectedDateString) }
