我有一个UICollectionView，它在顶部有一个清晰的单元格，用于显示下面的UIScrollView。 UIScrollView应向左/向右平移。如何将左/右滚动向下传递到UIScrollView，同时仍允许在整个UICollectionView上上/下滚动？
------------------- < Clear cell in clear UICollectionView

| A | UIScrollView with 3 pages is behind
| | the UICollectionView. Allow scroll left/right
| ... | for pages and up/down for table.
