title: Getting coordinates points of the path using Google Map on Iphone MKMapView
body: <p>I am using the MKMapView SDK.
  I can get the coordinates of two points. but how do I get the path ,array of coordinate points generated by Google so, I can draw that path on the MKMapView?</p>
  
  <p>Google is the one that calculated the shortest path between the 2 points. How I do that on the Iphone? </p>
  
  <p>where and how to generate that route.kml file??</p>
  
  <p>// Locate the path to the route.kml file in the application's bundle
      // and parse it with the KMLParser.
      NSString *path = [[NSBundle mainBundle] pathForResource:@"route" ofType:@"kml"];
      kml = [[KMLParser parseKMLAtPath:path] retain];</p>
