自动调整collectionview单元格大小显示不正确,行间距最小

我有autosize cell collection视图,需要在其中水平显示数据。一切正常,但我需要在两个电池之间设置5倍的间距 minimumLineSpacing 属性和问题已启动 由于行距问题,我的上一个单元格无法正确显示。这是照片

这是密码

extension TopicVC : UICollectionViewDelegate,UICollectionViewDataSource,UICollectionViewDelegateFlowLayout
{
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 5
    }

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
        return 5.0
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: HastagCell.identifier, for: indexPath) as! HastagCell
        let index = indexPath.row % arrClrFollowTopic.count
        cell.btnHashTag.backgroundColor = Color.custom(hexString: arrClrFollowTopic[index], alpha: 1.0).value
        if indexPath.row % 3 == 0
        {
            cell.btnHashTag.setTitle(strTitle: "#Testing 123545")
        }
        else
        {
            cell.btnHashTag.setTitle(strTitle: "#Testing")
        }
        return cell;
    }

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    }
}

视图加载

override func viewDidLoad() {
        super.viewDidLoad()


        self.objCollectionView.register(HastagCell.nib, forCellWithReuseIdentifier: HastagCell.identifier)



        if let collectionViewLayout = self.objCollectionView.collectionViewLayout as? UICollectionViewFlowLayout{
            collectionViewLayout.estimatedItemSize = CGSize.init(width: 1.0, height: 1.0)
        }

        self.objCollectionView.delegate = self
        self.objCollectionView.dataSource = self
        // Do any additional setup after loading the view.
    }
