ios - a single static header that changes as you scroll
===

I've been searching a ton and can not seem to find an answer...

I have a tableView which scrolls all the days of all the months. And I have a titleForHeaderInSection: and viewForHeaderInSection: which displays a section header at the top of each month-section which replaces appropriately at the top, cool.   But how can I create a single header where the titleLabel changes to the proper month as I scroll (in other words, Not have multiple section headers, just one)?  

I can't tell whether this should be setup as "one (big) section with a header that changes" or "a headerView that changes", or whatever...  Any examples would be greatly appreciated. Thank you in advance.
