title: How do i open Google Maps for directions using coordinates on the iphone
body: <p>I am using UIMapView to display locations on the iPhone. I want to do a directions from current location to the location of interest, I don't think its possible using MapKit (but if it is please inform) So I will open either the Google Maps application or safari to display it.</p>
  
  <p>Can i do this by specifying co-ordinates from (current location) to co-ordinates (the location of interest) I have these longitudes and latitudes. Or do i have to use street addresses?</p>
  
  <p>If I do have to use street addresses, can i get them from the latitude and longitude.</p>
