Set custom selection color in FSCalender for selected dates

Question

Hi I am new to iOS and was working to create a calendar using FSCalendar which is pretty awesome but I am unable to change the selection color of the range of dates in between the first selected date and last selected date. They are all of same colors. I want to display a lighter tone in between the two dates. For Example: Apart from 2nd Dec and 5th Dec in the screenshot screenshot, all the dates should be a different color.

How do I change the color of the dates inside the range excluding the final and initial dates?

Answer 1

By using FSCalendarDelegateAppearance you can control the selection fill color for individual dates.

Step 1. Ensure you have set the delegate:

yourFSCalendarObject.delegate = self

Step 2. Implement available FSCalendarDelegateAppearance delegate methods:

In your case: calendar(_:appearance:fillSelectionColorFor:)

Example:

extension YourClassName: FSCalendarDelegateAppearance {

    func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, fillSelectionColorFor date: Date) -> UIColor? {
        //where startDate and endDate make the range of dates
        if date >= startDate, date <= endDate {
            return .yellow
        } else {
            return nil
        }
    }

}
