title: reload uitableview to bottom cell
body: <p>im creating a chat app, and I display each message thru a cell in the uitableview. However, each time i reload the tableview, it displays the content from the first cell down. I want to arrange my table so that when it reloads, it is "scrolled" all the way down, thus displaying the most recent message.</p>
  
  <p>I've done some research on the docs, but im very very new to programming so im not sure how to set it up. I think i need the reloadRowsAtIndexPaths method, but im not sure how to implement it. Thanks!</p>
