I don't know if any of you have heard of "tweejump" (an open source game inspired by Doodle Jump, PapiJump, etc). The creator(s) at iPlayful, Inc. released the source code (yes, the Xcode project). There are no xibs or nibs in this whole Xcode Project. And, yet enough, there are no pictures of the animation for the bird. Although, there is a picture called "sprites.png", that does have the animation for the bird (the one that is jumping), along with several other animations that don't have their OWN image file. Would editing the "sprites.png" and putting a new animation over the old one change the animation for the bird when the application is built? If not, how would I change the animation for the main character?
It looks to me like from what you are describing that it is a "sprite sheet".
Try googling it and you will see many examples.
Essentially it is one image with all of the art assets placed on it and they are
accessed by calling their coordinates. If you have an animation of a character
walking or throwing a punch, your sprite sheet will contain every frame of
that animation, as well as other art assets. I haven't used them myself so you will have to research it to find out how to use them.
To simply change this example, I would load sprite.png into Photoshop or whatever image editor you use and place your desired character in EXACTLY the same place and at the same size as the bird is now.
You should also find a plist file with the same name or close to it.
Was that app written with cocos2d? Either way, if you create each of your individual frames for the animation, you will likely need to create a new plist file also, and then also change the for loop that loads those images from the plist so that the loop refelcts the correct number of animation frames. This may sound difficult at first until you look into one of two apps I am aware of, Zwoptex or TexturePacker. I use Zwoptex, there is an online flash version. Google "zwoptex flash". From there you just need to import your images, align them (using the align menu) then export the texture file and the coordinates (plist file). Pretty easy app to use really.

Good Luck!!
Im looking at the project and am wondering were in the code can i change the size of the objects on the Sprite file
