title: How to target both iPhone and iPad resolution on Flash CS6
body: <p>I am building a small game for iOS on Flash CS6 and I want to target both iPad and iPhone resolutions, also supporting retina display if possible. I've played with the movie properties and the Air for iOS settings, but I am still in confusion about the screen resolutions. I want to make a HD (retina-enabled) game, and I want to target the non-retina models too. Which resolution should I use? (I'll be having only landscape) Should I go with 2048x1536 (iPad Retina), 1024x768 (iPad non-retina), 960x640 (iPhone/iPod touch retina), or 480x320 pixels (iPhone/iPod touch non-retina)? I've set the resolution to High in Air for iOS settings, left the default resolution (960x640) unchanged, but when I tested it on iPad 3, the resolution wasn't HD, even though my graphics were vector (made in Flash). There was also background color visible around the corners, compensating for the aspect ratio difference of iPhone and iPad. Why can be the App rendering in non-retina resolution even though I've checked it at the settings for iOS? And more importantly, what is the best approach for targeting both screen resolutions in a single app?</p>
  
  <p>Thanks,
  Can.</p>
