I did this just for grins to see what I came up with. Boy was I
surprised!
Here's a listing of the calls made loading a table with 2 sections
where the first section has 1 row and the second has 2 rows. Each
section has a header title and a footer title.

Received: tableView:titleForFooterInSection:
To summarize, there are:
9 tableView:titleForHeaderInSection:
8 tableView:titleForFooterInSection:
2 numberOfSectionsInTableView:
2 tableView:numberOfRowsInSection: -// I hope we all agree
3 tableView:cellForRowAtIndexPath: --// these make sense
But can anyone explain all the other duplicate calls?
Waiting with baited breath.
