Also, the cell "types" are determined by the string you provide in
initWithFrame:reuseIdentifier:
Each unique identifier will have its own reuse pool which can later be
recalled by using the same string with
dequeueReusableCellWithIdentifier:
The idea is that cells that have the same basic layout will be typed
the same. If you have a couple different cell layouts, then you should
use a couple different type identifiers. The goal should be that after
you dequeue a cell, all you need to do is update it with the data from
your data source - you shouldn't need to layout views at that point.

A different cell instance is used for each visible row. The point
of the queue is so that you don't have to instantiate a new cell for
every row in your table. The UITableView will "recycle" old cells
(ie, cells that are no longer visibly on the screen) when it is
about to display a new cell. This helps keep the overall memory
footprint down.

In the template UITableViewController that instantiates cells by
first attempting to dequeue them, is that same dequeued cell used
to draw all visible rows, or is there a separate cell used for each
row? The docs I've read mention queueing different cells of
different types, so it's obvious in that case that the cells are
different.
If it's the case that only one cell is used, then how do you handle
the state related to, e.g., animating or touch tracking?
