{
    if (!self.detailViewController) {
        self.detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
    }
   
    self.detailViewController.detailItem = [self.products objectAtIndex:[indexPath row]];
    [self.navigationController pushViewController:self.detailViewController animated:YES];

hello
 
do not too much focus on what you are not understand if you study this book by yourself ,it is a good habit that when you meet something you are not understand just goto a small skip .

to solve the problem you can take a try if the code is in right documents,thank you
