Draw Lines between pins with iphones Map Kit

Is it possible to draw custom lines between two or more locations with the MapKit? Or do I need a custom overlay? Is there some kind of tutorial about this topic?

I have a working "G开发者_C百科oogle Maps Application" and now I want to connect my locations with straight lines.
