objective c - Add rows to UITableView when scrolled to bottom

Question

Is there a way to trigger an event, such as with an IBAction, when a user scrolls to the bottom of a UITableView? I would like to add more rows if this happens. How do I do this?

Answer 1

Unless it′s a little late, but i think i found a better solution:

instead of

 - (void)scrollViewDidScroll: (UIScrollView)scroll

i used

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate

This is much more convenient, cause the event is only triggered once. I used this code in my application to load more rows in my tableview at the bottom (maybe you recognize this type of reloading from the facebook application - only difference that they are updating at the top).

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate {    
    NSInteger currentOffset = scrollView.contentOffset.y;
    NSInteger maximumOffset = scrollView.contentSize.height - scrollView.frame.size.height;

    if (maximumOffset - currentOffset <= -40) {
        NSLog(@"reload");
    }
}

Hope anyone will help this.
