title: Setting UIITextView border color
body: <p>I would like to set the silver color for my UITextView border. I tried this:</p>
  
  <pre><code>theGroupTextLabel.layer.borderWidth = 3.5f;
      theGroupTextLabel.layer.borderColor = [[UIColor whiteColor] CGColor];
  </code></pre>
  
  <p>...but in the color option there are only some colors like whiteColor, BlackColor, Green...</p>
  
  <p>What if I want silver?</p>
