title: Documentation for NSString sizeWithFont:forWidth:lineBreakMode: method (in the iPhone SDK)?
body: <p>I can't find the documentation for the NSString sizeWithFont:forWidth:lineBreakMode: method (see <a href="https://stackoverflow.com/users/582/kevin-ballard">Kevin Ballard</a>'s answer to "<a href="https://stackoverflow.com/questions/406212/sizing-a-uilabel-in-the-iphone-sdk-to-fit">Sizing a UILabel (in the iPhone SDK) to fit?</a>") in the NSString Class Reference in the iPhone SDK Developer Documentation.  Where should I look?</p>
  
  <p><strong>Update</strong>: I hadn't subscribed to an iPhone OS Library doc set, so my search didn't work.</p>
