iphone - Can I interact with a UIView subview and have it positioned behind a fullscreen UICollectionView sibling view?

Question

I have a UIViewController that has a UICollectionView subview (clear background) that fills up the entire screen. I also have another subview (picture of a cloud) that has a gesture recognizer attached to it that I can move via touch.

Is it possible to have that cloud subview appear behind the collectionView, above the background view, and still touchable? So far I can only get it to work on top of the collectionView, otherwise I can't interact with it.

Answer 1

不，除非您的 collectionView 是您的 cloudView 的子视图，否则您不能这样做，但如果您这样做，您的 collectionView 也会随之移动。

如果您的 cloudSubView 在 CollectionView 后面，那么它将不会收到触摸，那么它将如何移动。
