How to determine if the user has scrolled to the bottom of the UITableView?

Question

How can I determine if the user has scrolled to the last cell/bottom of a UITableView?

Answer 1

UITableView inherits from UIScrollView, and scroll view exposes a contentOffset property (documentation here).

Use this with a bit of math to determine if the contentOffset is within frame.size.height of the bottom.

Update: here's a stab at a formula that will give you what you want:

if(tableView.contentOffset.y >= (tableView.contentSize.height - tableView.frame.size.height)) {
  //user has scrolled to the bottom
}

Answer 2

Use NSArray *paths = [tableView indexPathsForVisibleRows];. Then check if the last object in that array is the indexPath for the final cell.
