Edit Question
Title
Body
I have two different UIImageViews . I'd like to make the top UIImageView blend in using the Screen blend mode with the bottom UIImageView . I know of the property of CALayer : compositingFilter and I know that it doesn't work in iOS. I've searched a lot for solutions, and I've found how one should subclass UIView and override drawRect . I've tried to set the context in drawRect to the screen blend mode, although it still draws every one of the images normally. Perhaps I am doing something wrong, or the approach should be different. Maybe I need OpenGL or CALayer to achieve this. Could someone assist?
