title: How to invoke iPhone Maps for Directions with Current Location as Start Address
body: <p>I know it's possible to start the iPhone maps application by calling <code>openURL</code> on a google maps URL with parameters <code>saddr</code> and <code>daddr</code> with location strings or Lat/Long (see example below). </p>
  
  <p>But I'm wondering if it's possible to make the start address be the <strong>"Current Location"</strong> maps bookmark so that I can use the <strong>Maps</strong> app's location handling code. My Google search has been pretty fruitless.</p>
  
  <p>For example:</p>
  
  <pre><code>[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat: @"http://maps.google.com/maps?saddr=%@&amp;daddr=%@", myLatLong, latlong]]];
  </code></pre>
  
  <p>Except with something to invoke the current location bookmark in place of <code>myLatLong</code>.</p>
