protocol CollectionViewCellDelegte {
    func collectionViewCellDelegte(didClickButtonAt index: Int)
}

class ImageCollectionViewCell: UICollectionViewCell {
    var index = 0
    var delegte: CollectionViewCellDelegte? = nil

    @IBAction func buttonAction(_ sender: UIButton) {
        if let del = self.delegte {
            del.collectionViewCellDelegte(didClickButtonAt: index)
        }
    }
}
