I know it\'s possible to start the iPhone maps application by calling openURL
on a google maps URL with parameters saddr
and daddr
wit
For iOS6 Maps App, you can just use the same URL posted above
http://maps.google.com/maps?saddr=%f,%f&daddr=%@
but instead of the Google maps URL, you use the url with maps://
resulting in the following URL: maps://saddr=%f,%f&daddr=%@.
Using 'Current Location' doesn't seem to work, so I stayed with the coordinates.
Antother good thing: It's backwards compatible: On iOS5, it launches the Google Maps app.
