iPhone 2D Game programming

I would like to start a project about creating a 2D game for iPhone. I have already created some iPhone apps but none concerning game. The idea is simple : the user must drive a ball into a simple route composed of some obstacles before he gets cached by a wall that always go done. (I don't know if it make 开发者_高级运维sense to you but the game environment will be simple).

I posted here because I have some questions :

• What should I use ? Opengl ES or only UIView objects ?
• Is there some framework that could help me ?

All ideas, advices, suggestions, links for good tutorials are welcome !

Thanks in advance for your help.

Ps: forgive my english, it's not my first language.

If you are focusing on 2D only, something like Cocos 2D would save you a lot of steps and let to focus on your game development.

It handles scene management, particle effects, sprite animation, physics, etc.

My personal favorite for 2D development is Corona.
