title: How to get a UIImage's image as an NSString?
body: <p>I need to get the value of a UIImage's image as a string.</p>
  
  <p>Previously I was doing:</p>
  
  <pre><code>if(images[imageNo].image == [UIImage imageNamed:@"image1.png"])
  {
  </code></pre>
  
  <p>But now I have a lot more conditions so I would like to use a switch, doing: </p>
  
  <pre><code>switch(images[imageNo].image)
  {
      case @"image1.png":
      break;
  }
  </code></pre>
  
  <p>Is there a way to achieve this? Thanks!</p>
