Created on 20 Apr 2016 · 16Comments · Source: WenchaoD/FSCalendar

Hey congrats for such a beautiful library. I have 2 arrays as - eventDateArray consisting event NSDates & another array as colouredDateArray having NSDate's to be coloured. How can I achieve the same ? Please reply.

For any future users in SWIFT wanting such functionality. Changing colour of particular dates -(take 2 array - prsentStudents - greenColor & absentStudents - redColor)

self.presentDatesArray = ["2016-04-03",
        "2016-04-06",
        "2016-04-12",
        "2016-04-25"];

        self.absentDatesArray = ["2016-04-10",
            "2016-04-18",
            "2016-04-15",
            "2016-04-16"];


    func calendar(calendar: FSCalendar!, appearance: FSCalendarAppearance!, titleDefaultColorForDate date: NSDate!) -> UIColor!
    {
        let dateString: String = calendar.stringFromDate(date, format: "yyyy-MM-dd")


        if presentDatesArray.containsObject(dateString)
        {
            return UIColor.greenColor()
        }
        else if absentDatesArray.containsObject(dateString)
        {
            return UIColor.redColor()
        }
        else
        {
            return nil
        }
    }

But be sure to implement - FSCalendarDelegateAppearance

Suppose am getting the dates after a network call, how can I change the fill color of particular dates?
For me calendar.reloadData() is giving me error :
* -[__NSCFCalendar components:fromDate:toDate:options:]: toDate cannot be nil
Future exception.
