title: Is there a better way to determine the right size for a UITableViewCell?
body: <p>I have a UITableView cell that is going to have a variable size depending on it's content (potentially several lines of text). </p>
  
  <p>SInce it appears that heightForRowAtIndexPath is called <em>before</em> I layout the cell, I just guess the correct height by calling [NSString sizeWithFont] on my text string. Is there a better way to set the height <em>after</em> I've laid out the text in the cell and have an idea of exactly what size it should be?</p>
