title: Change UITextView text color with animation
body: <p>Just a simple question.
  Is it possible to change the text color of UITextView with a animation?  </p>
  
  <pre><code>[UITextView beginAnimations:nil context:NULL]; 
  [UITextView setAnimationDuration:2.0]; 
       textView.textColor = [UIColor grayColor];  
  [UITextView commitAnimations];   
  </code></pre>
  
  <p>Cheers!<br>
