How do I put a SuperView on top of a SubView?

I want to put a SuperView (with a transparent background) on 开发者_如何学Gotop of my SubView. Is there a way of doing that?

Thanks in advance!

1. Remove your "SubView" from your parent view.

2. Add your "SuperView" as a subview of your parent view.

3. Add your "SubView" as a subview of "SuperView".
