Dynamically create sprite images for Cocos2d-iPhone

I'm working on a platformer, and looking for a way to create a sprite for an arbitrarily sized platform. For example, I may know I have a platform that shou开发者_高级运维ld appear 200 pixels wide by 32 pixels high, and, say, I have a texture of bricks that I can tile to fill that area. I may also want to draw a black border around the platform. Is this possible at all? Anyone have any ideas for how I might go about doing this? I could always try generating the image on the fly and building a sprite with that image, but I sincerely doubt (hope) that this isn't the most efficient way of doing something like this.

Cheers, Alex

You can use tiled maps for the platform. It will require you to plan your textures a bit differently, but it will probably yield better results.
