I feel like this ought to be simple, but after searching high and low I can't find an answer to my question. I'm developing page swiping funtionality similar to Mobile Safari, where one page will fade out as it is swiped out of view and the other page fades in. Each "page" is a plain, white UIView with a small UIImageView, displaying a partly white image, overlayed. I fade in and out by changing the alpha as the views move from side to side. I've tried just adjusting just the container UIView's alpha, as well as adjusting that and the subview UIImageView's alpha, and neither gives me the results I'm looking for, which would be a nice and equal dimming of both. Unfortunately I can't post images here yet....
My initial solution was to place another image below the UIImageView which was the same color as the background gradient. This actually worked well, but for reasons I won't go into (and are not relevant to the problem) this solution is no longer acceptable.
Am I just missing something obvious here? Thanks in advance for your help!
