How can I detect when a tableview has been scrolled to the bottom so that the last cell is visible?

A:
Implement the tableView:willDisplayCell:forRowAtIndexPath: method in your UITableViewDelegate and check to see if it's the last row.

thanks for the tip. I'm actually using this method to trigger an event and it looks like because it's "Will" display, it happens before it actually displays the cell. Is there a method that fires after the cell is displayed?

Alas, no. You could fudge a little by using `performSelector:withObject:afterDelay` with a very short delay to call a method that does what you need.

A:
Inside tableView:cellForRowAtIndexPath: or tableView:willDisplayCell:forRowAtIndexPath: like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
...
NSInteger sectionsAmount = [tableView numberOfSections];
NSInteger rowsAmount = [tableView numberOfRowsInSection:[indexPath section]];
if ([indexPath section] == sectionsAmount - 1 && [indexPath row] == rowsAmount - 1) {
// This is the last cell in the table
}
...
}
