如何在Xamarin.ios中实现日历日期选择器而不是默认日期选择器

using JTAppleCalendar;

public class CalendarViewController : UIViewController
{
    private JTAppleCalendarView calendarView;

    public override void ViewDidLoad()
    {
        base.ViewDidLoad();

        // 创建日历视图的容器
        var calendarContainer = new UIView
        {
            TranslatesAutoresizingMaskIntoConstraints = false
        };
        View.AddSubview(calendarContainer);

        // 设置日历视图的容器约束
        calendarContainer.TopAnchor.ConstraintEqualTo(View.SafeAreaLayoutGuide.TopAnchor).Active = true;
        calendarContainer.LeadingAnchor.ConstraintEqualTo(View.LeadingAnchor).Active = true;
        calendarContainer.TrailingAnchor.ConstraintEqualTo(View.TrailingAnchor).Active = true;
        calendarContainer.BottomAnchor.ConstraintEqualTo(View.BottomAnchor).Active = true;

        // 实例化JTAppleCalendarView对象
        calendarView = new JTAppleCalendarView
        {
            TranslatesAutoresizingMaskIntoConstraints = false,
            CalendarDelegate = new CalendarDelegate(),
            CalendarDataSource = new CalendarDataSource(),
            ScrollingMode = ScrollingMode.StopAtEachCalendarFrame,
            ShowsHorizontalScrollIndicator = false,
            ShowsVerticalScrollIndicator = false,
            AllowsMultipleSelection = false,
            FirstDayOfWeek = DayOfWeek.Sunday,
            TodayButtonColor = UIColor.SystemBlueColor
        };
        calendarContainer.AddSubview(calendarView);

        // 设置日历视图的约束
        calendarView.TopAnchor.ConstraintEqualTo(calendarContainer.TopAnchor).Active = true;
        calendarView.LeadingAnchor.ConstraintEqualTo(calendarContainer.LeadingAnchor).Active = true;
        calendarView.TrailingAnchor.ConstraintEqualTo(calendarContainer.TrailingAnchor).Active = true;
        calendarView.BottomAnchor.ConstraintEqualTo(calendarContainer.BottomAnchor).Active = true;
    }
}

public class CalendarDelegate : JTAppleCalendarViewDelegate
{
    public override void DidSelectDate(JTAppleCalendarView calendarView, NSDate date, CellView cell, CalendarCellState state)
    {
        // 处理日期选择事件
        // 在这里执行你的自定义操作
    }
}

public class CalendarDataSource : JTAppleCalendarViewDataSource
{
    public override ConfigurationParameters GetConfigurationParameters(JTAppleCalendarView calendarView)
    {
        // 配置日历视图的参数
        var startDate = NSDate.Now;
        var endDate = startDate.AddYears(1);
        var parameters = new ConfigurationParameters(startDate, endDate);
        return parameters;
    }
}
