FSCalendar - Change the title color of Particular Dates Using Swift

Question

Hello all I'm working on the WenchaoD's FSCalendar now a days.I successfully loaded the calendar with many events.But now the question is how to change the date's title color for particular dates.Can anyone suggest me how to do this?

Answer 1

1) First of all implement FSCalendarDelegateAppearance

2) Let's assume you are having an array of some dates,let's declare an array first.

var somedays : Array = [String]()

3) Now you will need formatter to change the string into date.

fileprivate let gregorian: Calendar = Calendar(identifier: .gregorian)
fileprivate lazy var dateFormatter1: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy-MM-dd"
    return formatter
}()

4) FSCalendarDelegateAppearance is having one method named : titleDefaultColorFor

5) Implement this method using below code.

func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, titleDefaultColorFor date: Date) -> UIColor? {

    somedays = ["2017-06-03",
                "2017-06-06",
                "2017-06-12",
                "2017-06-25"]
    let dateString : String = dateFormatter1.string(from:date)

    if self.somedays.contains(dateString) {
        return .green
    } else {
        return nil
    }
}

6) Run this code.Happy coding.
