Sure, you just have to manage it manually:

1. Add one extra row to your table view.
2. In tableView:cellForRowAtIndexPath:, if the indexPath corresponds to the last possible row (which is the extra row you added), create a cell that represents the button.
3. In tableView:didSelectRowAtIndexPath:, if the indexPath corresponds to the last possible row, have your datasource load the additional data and send a insertRowsAtIndexPaths:withRowAnimation: to your table view.
