Delete row properly in Master View

Question

I have Split View. Master View is a table. When I delete selected row in Master View the Detail View still stays on screen and user can interact with it. How can I hide it until another row in Master View will be selected?

Edit:

I use the following code in master view controller to populate detail view controller's view:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{     
    [self.detailViewController loadData];    
}

Answer 1

In my Application I use an UILabel covering the whole detailview with the text "Select an item from List" until another row is selected.
