I have a image, I am using code as below to set it as UIView's background color, but I found there are black color, how can I avoid black with Transparency?
As you have not set the opaque property of the view to NO the drawing system assumes (as it should) that the view has no areas with alpha < 1.0. I'd try setting that property.
