您必须创建其标题视图

- (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPathUICollectionReusableView *reusableview = nil;

if (kind == UICollectionElementKindSectionHeader) {
    RecipeCollectionHeaderView *headerView = [collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:@"HeaderView" forIndexPath:indexPath];
    NSString *title = [[NSString alloc]initWithFormat:@"Recipe Group #%i", indexPath.section + 1];
    headerView.title.text = title;
    UIImage *headerImage = [UIImage imageNamed:@"header_banner.png"];
    headerView.backgroundImage.image = headerImage;

    reusableview = headerView;
}

if (kind == UICollectionElementKindSectionFooter) {
    UICollectionReusableView *footerview = [collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionFooter withReuseIdentifier:@"FooterView" forIndexPath:indexPath];

    reusableview = footerview;}
    return reusableview;}
