I had an idea to get something really simple up and running on my phone as a way to learn. I just wanted to get a large image to scroll up and down (the image is the same width as the screen so horizontal scrolling isn't necessary). I've managed to do it but there's one problem. The image I chose is 640x4000 so that it'd fit the screen width perfectly and have enough room to scroll a bit. I made the scroll area the same dimensions. Then when I run it it ends up being 2x the width of the screen. I "fixed" it by halving the scroll area and the image size but why can't I get it to build it at retina display resolution? Is there a simple switch I'm missing? Any help would be appreciated.
