UILabel numberOfLines
<p>I need to adjust <code>numberOfLines</code> of label in <code>cellForRowAtIndexPath</code>. Label is in word wrap mode.
However, the actual calculation of label's height is taking place in <code>heightForRowAtIndexPath</code>. </p>

<p>How to calculate <code>numberOfLines</code> in <code>cellForRowAtIndexPath</code>? For now I'm just using some very big number.</p>
