Information on how to open a map application (GoogleMaps) with a URL scheme on iOS and provide route guidance with multiple transit points.

let urlStr:String="comgooglemaps-x-callback://"+"?f=d&saddr=35.681298,139.766268&daddr=35.658598,139.745454"+"&x-success=source://?resume=sourceap;sour="Airportpp

UIAApplication.sharedApplication().openURL (NSURL(string:urlStr)!)

As mentioned above, we can guide the route from Tokyo Station to Tokyo Tower using the URL scheme, but would it be possible to guide the route through another point (Roppongi Hills) on the way?

If you can provide route guidance (car navigation) with a via point, I don't mind Google Maps, but Apple Maps and Yahoo Maps...

Thank you for your cooperation.
