should we use one big background image and scale that down for iphone4/5. but i read scaling is bad from 1334 to 960?? then what should we do for performance,should we use default-567h@2x.png for iphone 5 ,default-667@2x.png for iphone 6 and default@2x.png for iphone4?

by doing this , what my final .ipa size or app bundle increased or is automatically distinguish per device specific resource during downloading or installing application????

please give me your best answer, i appreciate it.

  • Which versions of iOS are you targeting? And is it only the launch image you're concerned about or would you like a more general answer? Reasons for questions: Apple introduced using a NIB for the launch image in iOS 8, which makes things a lot easier. – Tommy Mar 19 '15 at 15:23
  • no ,not launch images background images like playable area. i am not taking about assets catalog launch images rather than resource images which my iphone use – abhishek Mar 19 '15 at 16:02
  • For a game-style app? So you possibly aren't even using UIKit? – Tommy Mar 19 '15 at 16:04
  • yaa,right game style app. bec differnt device have different image resolution so scaling one big image is not good that's why should we use images that already scaled but , doing this it will increase the app bundle size – abhishek Mar 19 '15 at 16:07
