title: iOS Google Maps Question
body: <p>I have reviewed the Apple Documentation (http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html) on sending a user to the Google Maps App and I have a question, "How do I have it automatically bring up directions from the user's current location to a predetermined lat/long location?</p>
  
  <p>The Apple Docs say to use "saddr=" and "daddr=" for the source and destination respectively, but it doesn't say how to acquire the user's current location.  Is there some sort of keyword such as "saddr=Current" or "saddr=Here" that will get the user's location?</p>
  
  <p>Obviously, this doesn't work:</p>
  
  <pre><code>[app openURL:[NSURL URLWithString:@"http://maps.google.com/maps?saddr=Here&amp;daddr=Chicago"]];
  </code></pre>
  
  <p>..if I was trying to send the user to Chicago.  Any thoughts?</p>
