title: Auto size UILabel text
body: <p>I have a <code>UILabel</code> with multi lines. I'm trying to get the text to auto size, and fit on the line it's in. So instead of:</p>
  
  <pre><code>longe
  st
  </code></pre>
  
  <p>The text size should become smaller so that it can fit on the same line:</p>
  
  <pre><code>longest
  </code></pre>
  
  <p>Note: I only need it for the first line.</p>
  
  <p>I tried the following:</p>
  
  <pre><code>label.adjustsFontSizeToFitWidth = YES;
  label.minimumScaleFactor=3.0;
  </code></pre>
  
  <p>That didn't work, so I tried <code>label.minimumScaleFactor=3.0 / 9;</code> (9 is the font size.) That also didn't work.</p>
