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()
};
