title: How to find out when UILabel wordwraps
body: <p>I have created a couple of different <code>UITableViewCell</code>s for my <code>tableViewController</code>, this is because I have different bits of data I want to display depending what comes back. Because of this each <code>UITableViewCell</code> is of a different height.</p>
  
  <p>This is all fine, However one of my <code>UILabel</code>s has to display a large <code>NSString</code>, so large that I have had to word wrap it onto a second line, The only issue here is that it messes up my <code>UITableViewCell</code> formatting.</p>
  
  <p>My question is, is it possible to flag or capture some type of action when a <code>UILabel</code> receiving a <code>NSString</code> has to use wordrap because the size of the <code>NSString</code> is too long?</p>
  
  <p>Or is there a way to calculate the physical length (not how many chars are in the string) of the <code>NSString</code> so I can decide hey I need to reformat my <code>UITableViewCell</code>..</p>
  
  <p>Any help would be greatly appreciated.</p>
