iOS Google Maps Transit Data

Question

Is it possible to use google maps transit data to show a publich transit route inside your application rather than sending a user to google maps app? I see that google maps on iphone does it well for switzerland (region i am interested in).

Check http://code.google.com/intl/en/apis/maps/documentation/directions/#TravelModes driving, walking and bicycling are there, but it seems like transit is not available.

Anybody got an idea or workaround?
