This question already has an answer here:
For an iOS app I want to draw a 3D cube and be able to rotate it with swipe gestures. Where can I find a tutorial or something for such a basic scenario? All I can find are deep reads for openGL but I think there must be something easier?
You can watch this tutorial..... http://www.raywenderlich.com/3664/opengl-es-2-0-for-iphone-tutorial
Cocos3d is a good framework to start with, and rather simple to use. Check the demo for examples, I think they have a rotating object inside as well.
