Answer 1

这是一个简单的实现，它只覆盖 UICollectionViewDataSource 协议(protocol)上的一个可选方法:

func numberOfSections(in collectionView: UICollectionView) -> Int {
    return 3
}

func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView {
    switch kind {
    case UICollectionElementKindSectionHeader:
        let section = indexPath.section

        switch section {
        case 0:
            let TitleHeader = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: homeHeaderReuseIdentifier, for: indexPath) as! TitleHeader
            return TitleHeader
        default:
            let Section1Header = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: sectionSpacingHeaderReuseIdentifier, for: indexPath) as! Section1Header
            return Section1Header
        }
    case UICollectionElementKindSectionFooter:
        let FooterView = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: homeFooterReuseIdentifier, for: indexPath) as! FooterView
        return FooterView
    default:
        return UICollectionReusableView()
    }
}


func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, referenceSizeForHeaderInSection section: Int) -> CGSize {
    return CGSize(width: collectionView.frame.width, height: 100.0)
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, referenceSizeForFooterInSection section: Int) -> CGSize {
    return CGSize(width: collectionView.frame.width, height: 100.0)
}
