body: <p>I have a application, what is download a xml file and after parser it. After the processing data visualize in a table view. Problem: When I download and parser the data I change the view (Sample viewController -> UITableViewcontroller). The tableview doesn't reloadData.
  First I download the XML from the server. After I hand to the XML parser the data:<p></p>
  
  <pre><code>NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:data];
  XMLParser *parser = [[XMLParser alloc] initXMLParser];
  [xmlParser setDelegate:parser];
  </code></pre>
  
  <p>When The XML parser complite the uitableview  appeared.
  Then I like to update the uitableview, but I don't know, how I do.
  <p>
  I try to use the following commands after the XML parser:<p></p>
  
  <pre><code>[[contactlist tableView] reloadData];
  [[contactlist tableView]performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:YES];
  </code></pre>
