Is it feasible to make iPhone apps using just OpenGL and not Cocoa Touch?

Question

I'd much rather code an app using pure C api such as OpenGL, rather that Cocoa Touch. So I'm wondering: is it feasible? Will I be able to maintain the same user experience that you get with Interface Builder?

Answer 1

None of the UI components have OpenGL equivalents. Is it possible? Yes. Is it sensible? No - you would be much better off learning how to use IB and the UIView classes. Coding the UI in OpenGL would be like painting your house with an artist's brush, using hand-made paint instead of Dulux.
