title: URL scheme for opening native calendar with specific date
body: <p>I have found the sample code to open calendar from my app, but i can't open at a specific date.</p>
  
  <pre><code>NSString* launchUrl = @"calshow://";
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString: launchUrl]];
  </code></pre>
  
  <p>Is there a way to add specific date at the end of the "lunchUrl" string so when the user opens the calendar it displays the given date.</p>
  
  <p>I have already tried the following formats: @"calshow://?=2013 12 19", @"calshow://?=2013-12-19", @"calshow://?=2013+12+19". None of these seem to work for me... any ideas what am i'm doing wrong?</p>
