Not having child alpha be influence by parent view

I have placed a button in a view and I want the view to be translucent, but the button to be solid. The button is taking on whatever alpha the the view has. How do I get the button to have it's own alpha?

Thanks in advance!

How are you changing the alpha of the view?

I am changing the alpha in the storyboard attributes inspector.

Well, the items in a view WILL be subject to the alpha of their parent view, that's the way it works, and for good reason. However, perhaps you can fake this out a bit:

Make your parent view fully opaque, alpha =1, but set it's background color to clear. Then, set your button however you want. If you want your view to appear translucent (but not completely transparent) then create a new UIView inside of the parent UIView (of the same size as the parent view) and give THAT UIView the alpha and background color you want users to see as "translucent".
