Can you do this with iOS? I only ask as I would normally do this with the Window Control object in a normal PC application but this option has been greyed out for iOS apps.
I'm making a retro pixel art game. I was going to amend the window sizes on the fly and have one set resolution for each aspect ratio. I was looking at doing 825x550 for 3:2, 760x570 for 4:3 and 960x540 for 16:9. The game is a conversion from a 700x500 Flash game.
