Hi David, I made it work eventually. I just figured out both the frame buffer and the render buffer must be bound before drawing. Now I have a fine blue screen, so I guess I can go ahead after a good sleep. :)

I use the GLKit for matrix operations. It is very handy. But I like being able to tinker with OpenGL the hard way: I begun as a assembly kernel programer, I still appreciate low level APIs over higher abstractions! Just a further question: on a CAEAGLLayer backed view, [view setNeedDisplay] does nothing, doesn’t it? Thanks for your answer!
