刷到其他月份时，FSCalendar自定义问题

Question

我正在尝试更改特定日期的填充颜色，这些日期是当前显示月份的一部分。

我的问题：这仅适用于最初显示的月份。 如果我前后滑动到下一个/上一个月，则背景色似乎分配给了随机日期。

示例

最初显示的月份（按预期工作）： 上个月（错误的颜色分配）：

我的视图控制器

import Foundation
import FSCalendar

// MARK: - Class: CalendarViewController
class CalendarViewController: UIViewController, FSCalendarDelegate, FSCalendarDelegateAppearance {

    // MARK: Instance Properties
    fileprivate lazy var dateFormatter: DateFormatter = {
        let formatter = DateFormatter()
        formatter.dateFormat = "yyyy/MM/dd"
        return formatter
    }()

    var uncessfulTrainingDays: [String] = []
    var notcompletedTrainingDays: [String] = []

    // MARK: IBOutlets
    @IBOutlet private weak var meetingInfoView: UIView!
    @IBOutlet private weak var milestoneReachedLabel: UILabel!
    @IBOutlet private weak var nextMilestoneLabel: UILabel!
    @IBOutlet private weak var calendar: FSCalendar!
    @IBOutlet private weak var nextMeetingDateLabel: UILabel!
    @IBOutlet private weak var nextMeetingDescriptionLabel: UILabel!

    // MARK: Overridden Methods
    override func viewDidLoad() {
        super.viewDidLoad()
        uncessfulTrainingDays = ["2019/01/06"]
        notcompletedTrainingDays = []
        meetingInfoView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.meetingPressed)))
        calendar.delegate = self
        calendar.select(Date())
        nextMeetingDateLabel.text = "26.12.2018"
        nextMeetingDescriptionLabel.text = "Meeting: check healing progress"
    }

    func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, fillDefaultColorFor date: Date) -> UIColor? {
        let currentDate = Date()
        let key = self.dateFormatter.string(from: date)
        let cal = Calendar.current

        // Is date in the curently displayed month?
        let monthOfDate = cal.component(.month, from: date)
        let monthOfCal = cal.component(.month, from: calendar.currentPage)

        let isInDisplayedMonth = monthOfDate == monthOfCal

        if isInDisplayedMonth {
            if self.uncessfulTrainingDays.contains(key) {
                return UIColor(named: "DarkRed")
            } else if date < currentDate {
                return UIColor(named: "PrimaryAccent")
            }
        }
        return nil
    }
}

当我前后滑动到上个月/下个月时，我的FSCalendar视图似乎没有正确更新。

任何想法我的代码有什么问题吗？

此功能解决了我的问题：

func calendarCurrentPageDidChange(_ calendar: FSCalendar) {
        calendar.reloadData()
}
