PrepareForSeque not called / fired

C / xcode geeks!

I have been struggling with this error for several hours, and it seems I have not found a solution, although it seems that many people have the same problem.

See code:

@implementation ListViewController

    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization
    }
    return self;
}

    NSLog(@"0");
    if ( [[segue identifier] isEqualToString:@"ShowMenu"] ){
        NSLog(@"1");
        DetailViewController *dvc = (DetailViewController *)[segue destinationViewController];
        dvc.menu = [self.blogPosts objectAtIndex:[[self.tableView indexPathForSelectedRow] row]];
    }
}

    [super viewDidLoad];

    // GET WEB DATA SOURCE (JSON)

    // The url

        // Get title
        // Will only retrieve data, if TITLE exists

        BlogPost *blogPost = [BlogPost blogPostWithTitle:[bpDictionary objectForKey:@"title"]];

        // Get the content
        blogPost.content = [bpDictionary objectForKey:@"content"];

        blogPost.thumbnail = [bpDictionary objectForKey:@"thumbnail"];

        blogPost.date = [bpDictionary objectForKey:@"date"];

        // Get price
        blogPost.price = [bpDictionary objectForKey:@"price"];

        // Add the object to blogPosts array
        [self.blogPosts addObject:blogPost];
    }
}

    [super viewDidUnload];

    return 1;

    return [self.blogPosts count];
}

    static NSString *CellIdentifier = @"PunTableViewCell";

    PunsTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[PunsTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    BlogPost *blogPost = [self.blogPosts objectAtIndex:indexPath.row];

    cell.menuTitle.text = blogPost.title;
    cell.menuContent.text = blogPost.content;

    if([blogPost.price length] == 0) {
        [cell.menuPrice setHidden:YES];
    } else {
        cell.menuPrice.text = blogPost.price;
    }



    return cell;
}


@end

As you can see, I have implemented NSLog () inside the preparation method, but it does not start.

Do you guys know what I'm doing wrong? I'm new to this, so I still haven't found out about it with all the iPhones. So with me if the solution is simple: o).

Thanks in advance!
