Dears, I’m trying to create a mask over the UIView. I tried adding a View with Alpha lower than 1, the problem was, all the alpha of the controls like images, buttons on this View has been set to same value.
How can I only change the background transparent but don’t impact other controls?
I also tried UIImageView, but seems UIImageView couldn’t attach other controls
Have a look at iPhone – Create a semi transparent rectangle with text I think you are having the same problem.
