I am new to using iOS Objective-C size classes like Regular, compact, Any. I found that Compact size classes are anything less than ~640 pts and Regular size classes are anything larger than ~640 pts . Is that correct for both iphone and ipad?
How can I use size class to make an image full screen on all the iphone and ipad devices and on any orientation? How many images will I need? Any help and insight is greatly appreciated!
