As an iPhone app developer, should I take some steps (especially for graphics) to make them look correctly on iPhone 4 "Retina Display" or is there no such an issue?

Thanks for your help and time.

Use vector graphics so everything scales beautifully on every device.

  • What type of file extensions are you speaking of? Would a .svg file be okay to use? I have never heard of using anything but a .png file. I use Inskcape to make my .png images from .svg files. – SAHM Oct 17 '11 at 01:25
  • Whatever's supported. I hope SVG is! – Emyr Oct 17 '11 at 08:41

If you're not using vector graphics you're going to want to make provide high res versions of all your images, otherwise it will look pants on the new display.

Other than that I don't think you'll need to do much else.
