Google Map Route Draw on IPhone

Question

I am developing an application that has two versions. One for web and another for iPhone.

In the web app, I am able to draw a route on the road (drawing the route automatically that follows roads/highways) and off road (draw direct line between two specific points).

Is there an API, for iPhone, that can be used to draw a route on the map? I am able to draw a straight line on the map between two nodes, but i am not able to draw a road map route in iPhone.

I am using iPhone 3.0 and SDK 3.0

Thanks.

Answer 1

Maybe you want to take a look at Craig Spitzkoff's MapLinesAndAnnotations sample that he recently wrote:

1. Drawing polyines or routes on a MKMapView (Using Map Kit on the iPhone)
2. Using MKAnnotation, MKPinAnnotationView and creating a custom MKAnnotationView in an MKMapView

Answer 2

there's a new API in iOS4 called MKOverlayPathView which does exactly this. MKOverlayPathView

I just wanted to update this post with this information so people get the whole story.
