Hello Martin,
You can use the
calendar:updateVisualsFoCell: method in this case. The day cell has a property
date, you can use this property to determine the date and customize it accordingly. The technique is demonstrated in
this help article. You just need to change the condition with one based on the
date property.
I hope this helps.
Regards,
Jack
