Answer 1

You can set the size with a property:

flowLayout.headerReferenceSize = CGSizeMake(0, 100);//constant height for all the items header

If Dynamic :

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout referenceSizeForHeaderInSection:(NSInteger)section {
    if (section == albumSection) {
        return CGSizeMake(0, 100);
    }

    return CGSizeZero;
}
