title: iOS UILabel bounding rectangle not sized correctly
body: <p>I have a UILabel (as highlighted in yellow), which has the following conditions applied to it.</p>
  <ul>
  <li>Label has variable text length</li>
  <li>Font set to 40</li>
  <li>Minimum font-size set to 20</li>
  <li>Number of lines set to 3</li>
  </ul>
  <p>Although this looks like a duplicated question I believe it is not. The issue I am having is that when the text exceeds the available 3 line length after being sized-down to 20 points, the UILabel's bounding box is sized incorrectly (i.e. note the extraneous spacing above and below the text).</p>
  <p>The end result should be a UILabel without any spacing. Is there are solution to this, while keeping the number of lines set to 3?</p>
