ios - 如何调整UICollectionView section的间距？

Question

我想调整UICollectionView各个section的间距，我尝试了在下面这些布局方法中设置间距，但是都没起作用，我每个section都有一个headerView

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets {
        return UIEdgeInsetsZero
    }
    
        func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAtIndex section: Int) -> CGFloat {
        return 1
    }
    
    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAtIndex section: Int) -> CGFloat {
        return 5
    }

Answer 1

그런 다음 footerView를 추가하면 footerView를 간격으로 사용할 수 있습니다
