cocos2d ipad支持retina (Use Retina Graphics In iPad) 

very easy:

in ccFileUtils.m search for

+(NSString*) getDoubleResolutionImage:(NSString*)path

and change the line

if( CC_CONTENT_SCALE_FACTOR() == 2)

for the line

if( CC_CONTENT_SCALE_FACTOR() == 2 || (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad))

Activate the retina in the appdelegate and DONE!
