With the new iPad (which has a different screen resolution of the iPhone/iPod Touch), how do I set the application to automatically size appropriately to the desired screen size?

            Although the iPad SDK is still under NDA at this time, the iPhone SDK which preceeds it introduced the ability to change the screen size:
- (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)opts
{
  UIScreen *s = [UIScreen mainScreen];    // ask for the main screen
  [window setFrame:[s applicationFrame]]; // get the application Frame for the screen
  return YES;
}
If you have used NIBs for the UI construction, you need to ensure that they're auto-resizable in order for them to flow properly.

            Read the iPad Programming Guide in the 3.2 SDK beta documentation. It will tell you everything you need. The NDA means we can't talk about it here publically.

            The issue is not in the code. It is in the project conversion from iPhone to iPad: http://www.cocos2d-iphone.org/forum/topic/4108
