title: UILabel: Custom underline color?
body: <p>I need the text of a <code>UILabel</code> to be black, but have a light gray underline under the text. Is this possible with <code>NSAttributedString</code> or <code>TTTAttributedLabel</code>? Or is custom drawing using Core Graphics needed?</p>
  
  <p>CLARIFICATION:
  I need a specific color text on a different color underline. Example: blue text on red underline.</p>
