FSCalender Events anzeigen in schnellen

Question

: Ich bin zu schnell, Bin Fscalender in swift mit es funktioniert gut, aber ich möchte die Ereignisse zu Fscalender hinzufügen, kann ich Ereignisse von Json

I Want Anzeigen erhalten die Ereignisse in Kalander kann ich einen Teil des Codes versuchen, aber seine Arbeit nicht einige Fehler immer pls helfen, wie die Ereignisse in Kalender anzuzeigen

var EventsData = [Event]() 

    all events are stored Into Event 


    fileprivate lazy var dateFormatter2: DateFormatter = { 
     let formatter = DateFormatter() 
     formatter.dateFormat = "yyyy-MM-dd" 



     return formatter 
    }() 

innen Json

 if let event_list = jsonData["events"] as? NSArray { 

           for i in 0 ..< event_list.count { 

            if let event = event_list[i] as? NSDictionary { 


             let data = event["date"]as?String 

             let newString = data?.replacingOccurrences(of: "/", with: "-") 

             print("new string data ",newString as Any) 

             self.compareDate(date: newString!) 

             self.EventsData.append(Event(
              eventId: event["eventId"] as? String, 
              eventName:event["details"] as? String, 
              //eventDate: event["date"] as? String 
              eventDate: newString)) 
            } 


           } 
} 

Zeigen Sie die Ereignisse

  func compareDate(date : String){ 
       let date = date 

       let dateFormatter = DateFormatter() 
       dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss" 
       let dateFromString : NSDate = dateFormatter.date(from: date)! as NSDate

       dateFormatter.dateFormat = "yyyy-MM-dd"

      } 


      func calendar(_ calendar: FSCalendar, willDisplay cell: FSCalendarCell, for date: Date, at position: FSCalendarMonthPosition) {

       return 0 

      } 

      func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, eventColorFor date: Date) -> UIColor? {

        let datenew = dateFormatter.string(from: dateFromString as Date) 


        print("new calendar",dateString) 


        if datenew.contains(dateString) { 
         return UIColor.purple 
        } 
       } 
       return nil 
      } 


      func calendar(_ calendar: FSCalendar, didSelect date: Date, at monthPosition: FSCalendarMonthPosition) { 
       if monthPosition == .previous || monthPosition == .next { 
        calendar.setCurrentPage(date, animated: true) 

        print("title date",date) 
       } 
      } 

, wie die Ereignisse in den Kalender anzuzeigen?

Answer 1

Nach einigen Änderungen in meinem Code es funktioniert gut Ereignisse in FsCalender

inside Json 



      if let event_list = jsonData["events"] as? NSArray { 

             for i in 0 ..< event_list.count { 
              if let event = event_list[i] as? NSDictionary { 
               self.EventsData.append(Event(
                eventId: event["eventId"] as? String, 
                eventName:event["details"] as? String, 
                eventDate: event["date"] as? String 
                ) 
               ) 
              } 

             } 
             self.do_refresh() 
            } 


    func do_refresh() 
     { 
      DispatchQueue.main.async(execute: { 

       self.calender.reloadData() 

       return 
      }) 
     } 


    Fscalender Implementation 

    func calendar(_ calendar: FSCalendar, willDisplay cell: FSCalendarCell, for date: Date, at position: FSCalendarMonthPosition) { 

      let dateFormatter3 = DateFormatter() 

      dateFormatter3.dateFormat = "yyyy-MM-dd" 
      let dateString3 = dateFormatter3.string(from: date) 

      strcond = dateString3 as NSString 
     } 


     func calendar(_ calendar: FSCalendar, numberOfEventsFor date: Date) -> Int { 
      let dateString = self.dateFormatter2.string(from: date) 
      print("this count first ",self.EventsData.count) 
      for d in EventsData{ 

       let date = d.eventDate 
       let dateFormatter = DateFormatter() 
       dateFormatter.dateFormat = "MM-dd-yyyy" 
       let dateFromString : NSDate = dateFormatter.date(from: date!)! as NSDate 
       dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss" 
       let datenew = dateFormatter.string(from: dateFromString as Date) 
       if datenew.contains(dateString) { 
        return 3 
       } 
      } 
      return 0 

     } 

     func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, eventColorFor date: Date) -> UIColor? { 
      let dateString = self.dateFormatter2.string(from: date) 
      for d in EventsData{ 
       let date = d.eventDate 
       let dateFormatter = DateFormatter() 
       dateFormatter.dateFormat = "MM-dd-yyyy" 
       let dateFromString : NSDate = dateFormatter.date(from: date!)! as NSDate 
       dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss" 
       let datenew = dateFormatter.string(from: dateFromString as Date) 


       if datenew.contains(dateString) { 
        return UIColor.init(red: 10, green: 200, blue: 399, alpha: 300) 
       } 
      } 
      return nil 
     }
