Question

Je suis nouveau rapide, je suis en utilisant Fscalender dans rapide, il fonctionne très bien, mais je veux ajouter les événements à Fscalender, je peux obtenir des événements de JSON

I Want Display les événements de calendrier, je peux essayer une partie du code, mais sa ne fonctionne pas obtenir des erreurs pls aident comment afficher les événements dans calendrier

var EventsData = [Event]() 

    all events are stored Into Event 


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



     return formatter 
    }() 

intérieur 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)) 
            } 


           } 
}

comment afficher les événements dans le calendrier?

Answer 1

Après quelques changements dans mon code, il fonctionne très bien montrant des événements dans 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 
     }
