当我点击单元格时，collectionView中的视图不会隐藏

Question

我想根据特定单元格上的点击隐藏与collectionView单元格相连的底视图。我已经尝试在“ didSelectItemAt”函数上执行此操作，但是它不起作用。

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) 
    {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as! CollectionViewCell

        cell.bottomView.isHidden = true    
    } 

   internal func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        return CGSize(width: collectionView.frame.width, height: collectionView.frame.height)
    }

    func numberOfSections(in collectionView: UICollectionView) -> Int {
        return 1
    }

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return self.lableArray.count
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as! CollectionViewCell
        let item = lableArray[indexPath.row]
        cell.imageView.backgroundColor = UIColor.randomColor()
        cell.lable.text = item
        return cell
    } 

Answer 1

通过更新解决了
让cell = collectionView.dequeueReusableCell（withReuseIdentifier：reuseIdentifier，for：indexPath）为！ CollectionViewCell

在didSelectItemAt中与

让cell = collectionView.cellForItem（at：indexPath）as！ CollectionViewCell

并添加带有类的UICollectionViewDelegate。
