title: How do I test the equality of two CLLocations
body: <p>I'm having a problem with isEqual:</p>
  
  <p>The code:</p>
  
  <pre><code> if (currentAnchor isEqual:currentBusiness.getCllLocation))
      {
          do a;
      }
      else
      {
          do b;
      }
  </code></pre>
  
  <p>currentanchor and currentbusiness.getCllocation are locations</p>
  
  <p>But if they are the same, why is function b called? Is something wrong with my code? </p>
