title: String to CLLocation latitude and Longitude
body: <p>I have two strings representing latitude and longitude like: "-56.6462520", and i want to assign then to a CLLocation object to compare to my current location.I tried the following code but i get errors only:</p>
  
  <pre><code>CLLocation * LocationAtual = [[CLLocation alloc]init];
  LocationAtual.coordinate.latitude = @"-56.6462520";
  LocationAtual.coordinate.longitude = @"-36.6462520";
  </code></pre>
  
  <p>and then compare the object with my actual location latitude and longitude. Any suggestions?</p>
