  </blockquote>
  
  <p>I try to sort this array decendingly as per following:</p>
  
  <pre><code>sortedArray = [arr_distance sortedArrayUsingComparator:^(id firstObject, id secondObject) {
      return [((NSString *)firstObject) compare:((NSString *)secondObject) options:NSNumericSearch];
  }];
  </code></pre>
