title: How should I correctly set 'Follow Readable Width' from interface builder?
body: <p>This is just a sample project I’m using to test some AutoLayout stuff.</p>
  <p>I’m using Follow Readable Width but then the label is still going all the way to the edges. I’ve tried a number of variations but nothing worked…</p>
  <p>When I inspect it from the viewDebugger, I see no trace of setting the <em>Readable Width</em>.</p>
  <p>Anyone know what am I doing wrong?</p>

  <p><strong>EDIT:</strong></p>
  <p>Followed instructions based on provided answer. I did the following:</p>
  <ul>
  <li>set 'Follow Readable Width' on the superview</li>
  <li>set constraints between the label and its superview's margins</li>
  <li>set my label's number of lines to 0</li>
  </ul>
