Monotouch framework in existing objective-c app

I would like to use my existing objective-c UI 开发者_如何学JAVAlayer, but call on a few monotouch functions from objective-c. How can I do that?

This is not possible as MonoTouch is a totally separate development environment.

MonoTouch compiles you code into an iPhone application.

A MonoTouch application however does have complete access to the iPhone API.
