I think you'll have to use OpenGL -- take a snapshot of the outgoing
and incoming pages and use them as textures on sheet of polygons.

I've written up a technique to simulate page curling using OpenGL, though you'll have to add a bit of work polishing it up to make it look as nice as in iBooks. I'm not convinced that Apple uses OpenGL for their transition, probably just fancy Core Graphics, but an advantage of using an pure OpenGL solution is that you can view the animation from any perspective, not just straight on.

If you're going to do that, take a look at Edward Patel's EPGLTransitionView:
