thank you for contacting us.
By design you could control which date is selectable and which is not by overriding -calendar:shouldSelectDate
method of TKCalendarDelegate. T
his method works only in case that TKCalendarSelectionMode
is not set to be TKCalendarSelectionModeRange.
We will appreciate if you elaborate a bit further about what is the effect you are trying to reach. This will help us to improve our product in a way that satisfies your request or provide a suitable work around for your case.
Looking forward to your reply.
