So I do tutorials on another Youtube page as Polynurb. I have been doing these tutorials on that page for several years, and a base of followers grew around that so I will continue to use that page. This tutorial was something I implemented on my menu UI stuff and in game UI stuff for the current XTerra project. It really helped me keep one set of assets that worked for both retina display and the non-retina display devices. I hope this helps some other iOS developers out there.
