I think you can get what you need using standard behavior for the header.

我认为您可以使用标头的标准行为获得所需的内容。

Set it up (probably in viewDidLoad):

设置它（可能在viewDidLoad中）：

UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];
flowLayout.headerReferenceSize = CGSizeMake(self.collectionView.bounds.size.width, 30);
// other setup
[self.collectionView setCollectionViewLayout:flowLayout];

Then answer a header view:

然后回答标题视图：

#define MY_HEADER_LABEL_TAG 128

- (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath {

    UICollectionReusableView *headerView = [collectionView dequeueReusableSupplementaryViewOfKind:
                                            UICollectionElementKindSectionHeader withReuseIdentifier:@"SectionHeader" forIndexPath:indexPath];
    UILabel *label = (UILabel *)[headerView viewWithTag:MY_HEADER_LABEL_TAG];
    if (!label) {
        label = [[UILabel alloc] initWithFrame:CGRectInset(headerView.bounds, 5, 5)];
        label.tag = MY_HEADER_LABEL_TAG;
        label.font = [UIFont boldSystemFontOfSize:12];
        label.textColor = [UIColor darkGrayColor];
        [headerView addSubview:label];
    }

    label.text = [NSString stringWithFormat:@"Section %d", indexPath.section];
    return headerView;
}
