Seems like there are 2 ways to go - either your sprites are laid out in a regular fashion and so can be picked off the sprite sheet in a programmatic way, like this first example. The other way is to use a tool like Zwoptex to create the sprite sheet and a corresponding plist that tells Cocos2d where to find the images on the sheet, see second example.

Tutorial for getting sprites off a sheet, using a regular layout:

http://getsetgames.com/2010/04/18/how-to-animate-sprites-in-cocos2d/

The basics are:

1. Get your images into one large image/texture
2. Create a CCSpriteSheet using that texture
3. Create a CCSprite using one of the images in your sprite sheet
4. Create a CCAnimation and populate it with CCSpriteFrame's - each representing a frame in the animation
5. Create a CCAnimate action to manage showing each frame and run it on sprite, voila.

The alternative is to use a tool like Zwoptex to configure your images on a sheet which will export the sprite sheet and a plist of details of the images on it.

The first third of this tutorial explains it:

There are several cocos2d tutorials avaliable around the net. Also take a look at their docs. Another good resource can be github.com where you'll find at least couple of opensource games made in cocos2d
