title: Problem updating UITableViewCells when rotating UITableView
body: <p>I have a UILabel in a custom UITableViewCell that gets resized when the device is rotated.  The text in this label needs to be recalculated after the rotation because I am cutting it down to size and appending some text at the end.</p>
  
  <p>E.g. the datamodel has: "This is a run-on sentence that needs to stop."</p>
  
  <p>In portrait mode it becomes "This is a run-on sent... more"</p>
  
  <p>In landscape mode it becomes "This is a run-on sentence that... more"</p>
  
  <p>From <code>(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation</code>
  I am able to access the visible UITableViewCells and update the descriptions.</p>
  
  <p>The problem seems to be that there are UITableViewCells that are cached but I can't get to.  When I scroll the UITableView after a rotation, one or two cells that are below the visible area after the rotation don't have the correct text in the label.  So they haven't been rendered via <code>(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath</code> - but they weren't returned by [tableView visibleCells] (or via looping through all views returned via [tableView subViews]).</p>
  
  <p>I've tried to access the "extra" cells via this method:</p>
  
  <pre><code>for (int index=max + 1; index &lt; max + 3 &amp;&amp; index &lt; [cellTypes count]; index++) {
      NSIndexPath *updatedPath = [NSIndexPath indexPathForRow:index inSection:0];
      UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:updatedPath];
      if (cell == nil) { continue; }
      [self updateCellForRotate:cell forRow:index];
  }
  </code></pre>
  
  <p>(where max is the biggest row returned from visibleCells) but cell is always nil.</p>
  
  <p>Is there anyway to flush the cache of UITableViewCells so that they don't get re-used?  Or to access them so I can update them?</p>
  
  <p>Thanks!</p>
