I’m using cocos2d-1.0.1-x-0.12.0, but I found that it had problem to display 1920 * 640 png file on +iPhone 4s+ and the new iPad, but on iTouch4 and iPhone4 it is ok. I also had tried cocos2d-1.0.1-x-0.13.0 which is the latest version. it also has this problem.
thnaks for replying, but my question is not about crossing-platform:why iphone4 and touch4 is ok, but iphone4s and new ipad not, this problem is really easy to reproduce.
