Are there any good tutorials for making an app - business app, not a game - scale to different device sizes?
I read about using letterbox and the size of 320x480 and making the backgrounds 380x570 and this looks fine on iPhone 4, but as soon as it jumps to iPhone 5 or 6, the top banner and bottom banner are no longer at the bottom and there’s a big stretch of the background at the top and bottom - effectively a NON-black letterbox.
Is there a way to always have it stretch? Or do I build it for the larger screen and leave bleed on the edges so it still displays everything when cropped?
Thanks!
