How can I do vertical paging with a UITableView?

Let me describe the situation I'm trying to do:

I have a list of items. When I go to ItemDetailView, which is a UITableView. I want to do paging here like: When I scroll down from the table view, I want to display the next element. Like in Good Reader:

Swap Examples http://img245.yfrog.com/img245/2073/pricethat.jpg I am currently trying to use two approaches, but both of them do not work for me. 1st: I allow my UITableView to view the scroll, and I have good animation, and everything works fine, but sometimes the UITableView gets an event instead of my scroll. And since UITableView is already a UITableView, this approach seems like a bad idea. Here is the code:

- (void)applicationDidFinishLaunching:(UIApplication *)application {
    // a page is the width of the scroll view
    scrollView.pagingEnabled = YES;
    scrollView.contentSize = CGSizeMake(scrollView.frame.size.width,   scrollView.frame.size.height * kNumberOfPages);

    scrollView.showsHorizontalScrollIndicator = NO;
    scrollView.showsVerticalScrollIndicator = YES;
    scrollView.scrollsToTop = NO;
    scrollView.delegate = self;
    [self loadScrollViewWithPage:0];
}

- (void)loadScrollViewWithPage:(int)page {
    if (page < 0) return;
    if (page >= kNumberOfPages) return;

 [self.currentViewController.view removeFromSuperview];
 self.currentViewController = [[[MyNewTableView alloc]initWithPageNumber:page] autorelease];

    if (nil == currentViewController.view.superview) {
        CGRect frame = scrollView.frame;
        [scrollView addSubview:currentViewController.view];
    }
}

- (void)scrollViewDidScroll:(UIScrollView *)sender {
    if (pageControlUsed) {
        return;
    }

    CGFloat pageHeight = scrollView.frame.size.height;
    int page = floor((scrollView.contentOffset.y - pageHeight / 2) / pageHeight) + 1;
    [self loadScrollViewWithPage:page];
}
- (IBAction)changePage:(id)sender {
    int page = pageControl.currentPage;
    [self loadScrollViewWithPage:page];

 // update the scroll view to the appropriate page
    CGRect frame = scrollView.frame;
    [scrollView scrollRectToVisible:frame animated:YES];

    pageControlUsed = YES;
}

: pop push of navigationController, ItemDetail . , .
