監測uitableview 向上滑動和向下滑動的事件

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    CGFloat height = _varietyTableView.frame.size.height;
    CGFloat distanceFromButton = _varietyTableView.contentSize.height - _varietyTableView.contentOffset.y;
    if (distanceFromButton == height)
    {
        NSLog(@"=====滑動到底了");
    }
    
    if (_varietyTableView.contentOffset.y == 0)
    {
        NSLog(@"=====滑動到頂了");
    }
}
