title: AutoLayout + UITableViewCell + Height (not worked)
body: <p>I am trying to autoresize table cell with autolayout.
  But it seems TableView ignores height constraints.</p>
  
  <p>I know that "tableView: heightForRowAtIndexPath:" can do this.</p>
  
  <p>But how to avoid to use height hardcoding ?
  Is any other ways ?</p>
