In cellForRowAtIndexPath, add a tag property to the subview of the cell in question. Also set the subview's hidden property to YES. Finally, set the cell's selectionStyle to UITableViewCellSelectionStyleNone.

if (thisIsTheIndexPathInQuestion) {
   CGRect theFrame = CGRectMake(...); // figure out the geometry first
   UIView *subview = [[UIView alloc] initWithFrame:theFrame];
   // further customize your subview
   subview.tag = kSubViewTag; // define this elsewhere, any random integer will do
   subview.hidden = YES;
   cell.selectionStyle = UITableViewCellSelectionStyleNone;
   [cell.contentView addSubView:subview];
   [subview release];
}

Then just react to what you describe in the appropriate UITableView delegate method: 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   if (thisIsTheIndexPathInQuestion) {  // you know how to check this
      UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
      UIView *subview = [cell viewWithTag:kSubViewTag];
      subview.hidden = !subview.hidden;  // toggle if visible
   }
}

Make sure your "special" cell has a different CellIdentifier and this will work.
