title: Is there any way refresh cell's height without reload/reloadRow?
body: <p>I make a view like imessage, just input text into the bottom text view. I use table view to do this, and the text view in the last cell. when I input long text that more than one line, I need the text view and the cell become tailer. so I need refresh cell's height. but if I use table view's reload or reload row, the content in text view will disappear and the keyboard will disappear too. Is there any way better to fix it?</p>
  
  <p>May be I should use tool bar to do it easy? but I still doubt table view can do it.</p>
