Events in FSCalendar are supplied via a DataSource, much like other datasource-based controls (i.e.UITableView).

This example subclasses FSCalendarDataSource and added a hard-coded list of event dates (normally you would set/retrieve those via SQLite, Realm, etc...)

public class CalendarDataSource : FSCalendarDataSource
{
    NSCalendarUnit calenderUnits = NSCalendarUnit.Year | NSCalendarUnit.Month | NSCalendarUnit.Day;
    NSCalendar calendar = new NSCalendar(NSCalendarType.Gregorian);
    List<NSDate> events;

    public CalendarDataSource()
    {
        events = new List<NSDate>();
        events.Add(NSDate.Now);
        events.Add(calendar.DateByAddingUnit(NSCalendarUnit.Day, 3, NSDate.Now, NSCalendarOptions.None));
        events.Add(calendar.DateByAddingUnit(NSCalendarUnit.Day, 5, NSDate.Now, NSCalendarOptions.None));
        events.Add(calendar.DateByAddingUnit(NSCalendarUnit.Day, 7, NSDate.Now, NSCalendarOptions.None));
        events.Add(calendar.DateByAddingUnit(NSCalendarUnit.Day, 9, NSDate.Now, NSCalendarOptions.None));
    }

    bool SameDate(NSDate date1, NSDate date2)
    {
        return NSComparisonResult.Same == calendar.CompareDate(date1, date2, calenderUnits);
    }

    [Export("calendar:hasEventForDate:")]
    public override bool HasEventForDate(FSCalendar calendar, NSDate date)
    {
        return events.Any((NSDate eventDate) => (SameDate(eventDate, date)));
    }

    public override nint NumberOfEventsForDate(FSCalendar calendar, NSDate date)
    {
        return events.Any((NSDate eventDate) => (SameDate(eventDate, date))) ? 1 : 0;
    }
}

Then instance the datasource and assign it to your calendar instance:

calender = new FSCalendar
{
    Frame = View.Frame,
    DataSource = new CalendarDataSource()
};
