   Seems like cocos2d have the problem to recognize -hd for CCSpriteFrameCache when I enable Retina Display mode. It seems like can't recognize "sprite1-hd.png". When I disable the Retina Display mode, there is no problem. Any idea?

   [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"character.plist"];
   CCSpriteBatchNode *charBatchNode = [CCSpriteBatchNode batchNodeWithFile:@"character.png"];
   [self addChild:charBatchNode];
   
   NSMutableArray *animFrames = [NSMutableArray array];
   [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"sprite1.png"]];

   Thanks max9xs, I seems can't find any solution from the link.

   I already have "character.plist", "character.png" & "character-hd.plist", "character-hd.png", but the frame in

   i. "character.plist" is "sprite.png" as frame name but in
   ii. "character-hd.plist" is "sprite-hd.png" as frame name

   Is this the problem mess it up?

   When running for auto detection of hd content you should not add -hd when loading files.
   Just create a content-hd.plist content-hd.png/pvr and a content.plist and content.png/pvr

   But there is currently a bug in cocos2d.
   Get the newest version of cocos from development branch, download this file here:
   CCTextureCache.diff
   and apply the patch to CCTextureCache.

   This should do the trick.

   @Andreas Loew : Hey I am also stuck with the same issue. The above link for CCTextureCache.diff doesn't seems working. Please provide me working link for patch. Thanks in advance.

   These problems were fixed a long time ago. I don't know which sprite sheet maker you are using but you should do the following:

   1) Use HD sprites to make an HD sprite sheet - do not use -hd on the sprite's names - e.g. enemy.png Name the sheet and the plist file with hd. E.g. spritesheet-hd.plist spritesheet-hd.pvr.gz

   2) Rescale the hd sprites (TexturePacker can do this on the fly) but do not change the names of the sprites. Keep them identical to the hd version. Create a sheet called spritesheet.plist and spritesheet.pvr.gz

   3) Read the spritesheet.plist and spritesheet.pvr.gz in your project. Do not append -hd while loading. Cocos2d chooses to use the -hd sheets when running on Retina display.

   4) Reference the sprites as enemy.png when using it in you app.

   Cocos2d does a lookup for the sprite's name in the sprite frame cache and then chooses the matching texture to render the sprite from (which is hd/sd). This is why the sprite's name must be identical but the sheet must have the proper ending.

   I hope this solves your problem.
