UITableView Detecting Last Cell

Question

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

Answer 1

I had some problems with the willDisplayCell method. This works for me:

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    let y = scrollView.contentOffset.y/(scrollView.contentSize.height - scrollView.frame.size.height)
    let relativeHeight = 1 - (table.rowHeight / (scrollView.contentSize.height - scrollView.frame.size.height))
    if y >= relativeHeight{
        print("last cell is visible")
    }
}

Just pass this in the delegate methods, and change 'table' to your tableView.
