Creating a cocos2d game that runs on ipad and iphone

I read a tutorial a while back and it seemed like the author got his application/game to run on ipad and iphone with the same code base. How is this done?

Is it really necessary to create 2 code bases for each v开发者_StackOverflowersion or how can it be run on both devices.

Obviously the size of the application will grow because of the resources, but is there a way to leave out things depending on the build target?

Not possible to leave out the resources that are not used. It is just the resources that is different. Need to prepare 2 sets of images for iphone and ipad. Codes if you are using cocos2d .99.5, it should be fine.

In the targeted device family, select iphone/ipad.
