Using the Texture Atlas with cocos2d

To use pvr images, you need// Enable pre multiplied alpha for PVR textures to avoid artifacts
[CCTexture2D PVRImagesHavePremultipliedAlpha:YES];

How to use pvr images and plist:

// Load the texture atlas sprite frames; this also loads the Texture with the same name CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache];
[frameCache addSpriteFramesWithFile:@"game-art.plist"]; 
Load sprite:
CCSprite* sprite = [CCSprite spriteWithSpriteFrameName:@"ship.png"];
