title: UIImageView image name comparision Issue
body: <p>Recently I found an issue regarding UIImageView image.</p>
  
  <p>My Intention is to find If UIImageView Contains the image(image.png) or not.</p>
  
  <pre><code>if([[self.ImgView.image isEqual:[UIImage imageNamed:@"image.png"]])
  {
     NSLog(@"Image View contains image.png");//In normal run....
  }else
  {
    NSLog(@"Image View doesn't contains image.png");//Once came back from background
  }
  </code></pre>
  
  <p>In normal run the above code is working fine.</p>
  
  <p>But it fails to work when application came to active state once it was sent to background.</p>
