UITableViewCell showingDeleteConfirmation example.

[cell addObserver: self forKeyPath: @"showingDeleteConfirmation"
          options: NSKeyValueObservingOptionNew context: NULL];
Then you implement the observer callback method:

- (void)observeValueForKeyPath: (NSString *) keyPath ofObject: (id) object
                        change: (NSDictionary *) change context: (void *) context
{
    if ( [keyPath isEqualToString: @"showingDeleteConfirmation"] )
    {
        UITableViewCell * cell = (UITableViewCell *) object;
        BOOL isShowing = [[change objectForKey: NSKeyValueChangeNewKey] boolValue];
        if ( isShowing == NO )
            cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        else
            cell.accessoryType = UITableViewCellAccessoryNone;
    }
}
