title: How to convert UIColor value to a named color string?
body: <p>I need to convert <code>UIColor</code> to an <code>NSString</code> of the color name. </p>
  
  <p>I tried:</p>
  
  <pre><code> NSString *colorString = NSStringFromClass([[UIColor redColor] class]); 
  </code></pre>
  
  <p>But <code>colorString</code> did not give @"redColor".</p>
