How to compare JSON api dates with FSCalendar and

问题:

I have displayed events dots in calendar but not able to display same events according to month in tableview , I want to display those events like if we change the month and tableview data events should be changed , I'am confused how it can be done . I'am using FSCalendar to display events like dot and in tableview .

import UIKit
import Alamofire
import SwiftyJSON
import ToastSwift

class CalendarViewController: UIViewController , UITableViewDataSource, UITableViewDelegate, FSCalendarDataSource, FSCalendarDelegate , FSCalendarDelegateAppearance{
    @IBOutlet weak var tableview: UITableView!

    @IBOutlet weak var menu: UIBarButtonItem!

    @IBOutlet weak var calendar: FSCalendar!

    var strcond : NSString?


    var calendarEvents : [Calendars] = []

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


        return formatter
    }()


    override func viewDidLoad() {
        super.viewDidLoad()

        menu.target = self.revealViewController()

        menu.action = #selector(SWRevealViewController.revealToggle(_:))

        if self.revealViewController() != nil {

            self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
            self.view.addGestureRecognizer(self.revealViewController().tapGestureRecognizer())
        }



        getCalendarEvents()



        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override func viewWillAppear(_ animated: Bool) {

    }
    override func viewDidAppear(_ animated: Bool) {
          }

    func getCalendarEvents(){

        let url = NSURL(string: "http://******/api/academics/getEvents")
        var request = URLRequest(url: url! as URL)
        request.httpMethod = "GET"
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")
        Alamofire.request(request).responseJSON(){ response in
            switch response.result{
            case.success(let data):
                print("success",data)

                let myresponse = JSON(data)

                    self.calendarEvents.append(calenadarObj)
                    print("notice",calenadarObj.Title)
                    self.compareDate(date: calenadarObj.StartDate)

            }
                self.tableview.reloadData()

            case.failure(let error):

        cell.events_txt.text = getdata.Title
        calendar.reloadData()
        return cell

    }
}

i have displayed events in dots like i have image

In image i have displayed all JSON api events datas data but it should be according to calendar month data. if calendar is swiped to next month then in tableview data should load to same months events. How it can be done?
