title: reloading a table view in an iphone app?
body: <p>I have a table view controller that makes an http request, which returns xml.  I parse the xml and display it in a UITableView.  The first time the http request is called everything works as expected.  The second time I call the http request: I receive the xml as expected, but the table does not update.  I am calling the reloadData method of the TableView every 2 seconds, so that is not the problem any ideas????</p>
