title: Calculate distance from Location - iPhone
body: <p>I'm trying to calculate the distance between two places user Core Location. I've found a few posts that state to use </p>
  
  <pre><code>-(CLLocationDistance)distanceFromLocation:(const CLLocation *)location
  </code></pre>
  
  <p>Found some other test code in the thread below:</p>
  
  <p><a href="https://stackoverflow.com/questions/1171138/cllocationdistance-nan">CLLocationDistance NaN</a></p>
  
  <p>I'm not sure how to put it all together, to get the result I want ?</p>
  
  <p>Anyone any thoughts ?</p>
  
  <p>Regards,
  Stephen</p>
