title: Multi-line NSAttributedString with truncated text
body: <p>I need a UILabel subcass with multiline attributed text with support for links, bold styles, etc.   I also need tail truncation with an ellipsis.  None of the open source code that supports attributed text inside UILabels (<code>TTTAttributedLabel</code>, <code>OHAttributedLabel</code>, <code>TTStyledTextLabel</code>) seem to support tail truncation for multi-line text.  Is there an easy way to get this?  </p>
