PushListView.m

//开始拖拽视图

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView

{

    contentOffsetY = scrollView.contentOffset.y;

}

 // 滚动时调用此方法(手指离开屏幕后)

- (void)scrollViewDidScroll:(UIScrollView *)scrollView

{

    //NSLog(@"scrollView.contentOffset:%f, %f", scrollView.contentOffset.x, scrollView.contentOffset.y);

    newContentOffsetY = scrollView.contentOffset.y;
