Use the method scrollViewDidScroll to check the content offset of the tableview's scrollview. check if the user is trying to scroll beyond the bottom bounds of the table view. if so, scroll back to end of tableview. this will not limit bottom bounce but will scroll back so quickly that user will not notice bottom bounces.

   - (void)scrollViewDidScroll:(UIScrollView *)scrollView {
        if (scrollView.contentOffset.y >= scrollView.contentSize.height - scrollView.frame.size.height) {
            [scrollView setContentOffset:CGPointMake(scrollView.contentOffset.x, scrollView.contentSize.height - scrollView.frame.size.height)];
        }
    }

///UPDATE-- If Tableview's content size will be less than its frame, above code may not work. you can use following in that case:

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {

    if(scrollView.contentSize.height > scrollView.frame.size.height)
    {
    if (scrollView.contentOffset.y >= scrollView.contentSize.height - scrollView.frame.size.height) {
       [scrollView setContentOffset:CGPointMake(scrollView.contentOffset.x, scrollView.contentSize.height - scrollView.frame.size.height)];
    }
    }
    else if (scrollView.contentOffset.y >=  0)
    {
         [scrollView setContentOffset:CGPointMake(scrollView.contentOffset.x, 0)];
    }
}
