title: Multiple screen resolution support in cocos2d v3?
body: <p>I am little confused with cocos2d v3's support for multiple screen resolutions. If I use <code>CCSetupScreenMode: CCScreenModeFlexible</code>, what should be the default resolution of the image that I provide?</p>
  
  <p>Currently, I have provided assets for all the iOS device resolutions along with suffixes and the correct images are loaded on iPhone "3.5inch" and iPad. However, the "-568h@2x" suffix for iPhone "4 inch" is not working fine. Am i using the wrong suffix?</p>
  
  <p>I would like to avoid the need to use macros to determine which device the game is running on and load the images accordingly. </p>
  
  <p>Thank you for your time!</p>
