The way you would do this is to implement tableView:willDisplayCell:forRowAtIndexPath in your UITableViewDelegate, and watch for the last row being displayed (using the indexPath argument).

When the last row is about to be displayed, set a flag and call -reloadData on your UITableView. This will force the table view's recalculation, and call your datasource where you should see the flag and add (say) 5 rows to the previous total number of rows (and also clear the flag).

Now, the row that will display will no longer be the last row (it will have 5 rows below it) and presto! Infinitely-scrolling table view.

Keeping track of the total number of rows (and their content) is left as an exercise for the reader.
