ios - UICollectionViewによる自動スクロール

Question

- (UICollectionViewCell *) collectionView:(UICollectionView *)collectionView        cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    SliderCollectionViewCell *cell = [collectionView    dequeueReusableCellWithReuseIdentifier:@"articleCellslider" forIndexPath:indexPath];
    NSDictionary *item = [_articleListslider objectAtIndex:indexPath.item];

   // set the article image
    [cell.image setImageWithURL:[item objectForKey:@"image"]];

  // set the text of title UILabel
    cell.title.text = [NSString stringWithFormat:@"%@\n\n\n\n", [item objectForKey:@"title"]];
    cell.title.textColor = [UIColor colorWithRed:33.0f/255.0f green:74.0f/255.0f blue:146.0f/255.0f alpha:1.0f];

    // set the text of summary UILabel
    cell.description.text = [NSString stringWithFormat:@"%@\n\n\n\n\n\n\n\n\n", [item objectForKey:@"description"]];
        cell.description.font = [UIFont fontWithName:@"Helvetica Neue" size:14];

    cell.targetURL = [item objectForKey:@"link"];
    cell.sliderphoto = [item objectForKey:@"sliderphoto"];
    cell.date.text = [NSString stringWithFormat:@"%@\n\n\n\n", [item objectForKey:@"pubDate"]];
    cell.category.text = [NSString stringWithFormat:@"%@\n\n\n\n", [item objectForKey:@"category"]];
    return cell;

}

私の意図は、このコレクション ビューの項目を自動的に水平方向にスクロールさせることです。

コレクション ビューのこの設定で自動スクロールを取得するにはどうすればよいですか?
