Make UIView and subviews translucent as a single layer, not individually

Question

When setting up UIView alpha (on iOS), it sets each subtask to the same value, but composes them with this alpha over their respective supervisors. Thus, the subparagraphs are mixed with their observations.

I do not want this to happen. I want the opacity applied to the UIView as a whole, and not to each individual view. I want to achieve the same effect as, for example, CSS3 opacity or apply opacity to a group of layers in Photoshop, and not to each layer individually.

However, the difficulty lies in the fact that in this UIView there is a UITableView and others that need to be interactive. And it is impractical to have an idea, which should be behind this top view.

My question is: what is the best way to achieve this?

Thanks!
Alec

Answer 1

The Info.plist setting displays the "Render with group opacity" option
