But can anyone explain all the other duplicate calls?
Why does it matter? If you have eight or nine sections it makes
perfect sense. Or you could have one section and it needs to draw
multiple times, and whoever designed the API didn't want to go through
the expense of a KVO observation, instead asking the delegate for the
header/footer each time it needed it.
But none of that matters.

But, as I thought I explained in the original post, the table only has
2 sections, 1 with 2 rows and 1 with 1 row.
The table is only being loaded once. So why does it take:
9 tableView:titleForHeaderInSection: calls for 2 sections
8 tableView:titleForFooterInSection: calls for 2 sections
2 numberOfSectionsInTableView: calls for a single load
In a table of this size, you're right - "Why does it matter".
But what if my real table has 99 sections? Why should I get bogged
down with 800-900 calls for section header titles and section footer
titles.
Seems like an incredible waste of effort. Just curious if anyone knows
why this happens. If you don't know why, just say so.
I happen to live in a world of disturbing images. What can I say?
