title: How to tell if MKLocalSearch returns an exact or approximate location
body: <p>I have run into an issue using MKLocalSearch where I am not able to tell if the result given back by MKLocalSearch is an approximate location or an exact location.</p>
  
  <p>For example:</p>
  
  <p>Feeding "500 3rd st, San Francisco, CA, 94107 to MKLocalSearch will return the exact coordinate for the address since that is an accurate address.</p>
  
  <p>Feeding a slightly off address such as "500 3rd st, San Francisco, CA, 94103", notice the zip code is wrong, returns a result with a coordinate matching the address, the coordinate is an approximate location and not the actual location.  It is off by a few blocks.  </p>
  
  <p>The problem is that the user might think that the address was correctly entered and the coordinate provided is the exact location.  </p>
  
  <p>Is there a way to distinguish between a result that is approximate and a result that is exact?  </p>
  
  <p>Below are the results spit out for the two above queries:</p>
  
  <p>Accurate Address:</p>
