如何在UICollectionView中顯示特定單元格的矩形

Question

我在視圖控制器中使用了UICollectionView並傳遞了一組圖像。我已啓用收集視圖的分頁。但是當我滾動到下一張圖像時，以前的單元格不會完全消失。它仍然處於邊緣。所以，how I can make only specific image/cell visible while scrolling left/Right.

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

    if collectionView == collection_LargeView 
    { 
     let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Large Cell", for: indexPath)as! LargeImageCell 
     cell.imageView_LargePic.sd_setImage(with: NSURL(string: array[indexPath.row]) as URL!) 
     cellIndex = indexPath 
     return cell 
    } 
    else 
    { 
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Picture Cell", for: indexPath)as! VendorPictureCell 
     cell.imageView_VendorPics.sd_setImage(with: NSURL(string: array[indexPath.row])as URL!) 
     return cell 
    } 
} 

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 


    return array.count 

} 

//當在底部收集視圖項目選擇了其他集合視圖滾動到indexPath

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { 
    if collectionView == collectionView_picturesCollection 
    { 
     Index = indexPath.row 
     collection_LargeView.scrollToItem(at: indexPath, at: .right, animated: true) 
    } 

} 

請解決這個問題。 謝謝。

FUNC的CollectionView（_的CollectionView：UICollectionView，佈局collectionViewLayout：UICollectionViewLayout，sizeForItemAt indexPath：IndexPath） - > CGSize {

if collectionView == collection_LargeView 
    { 
    return CGSize(width: self.view.frame.size.width, height: 524.0) 
    } 
    else{
