收集单元全屏显示

Question

请帮助将采集单元发送到全屏模式。我在这里检查了所有主题： Expand a cell to full screen when selected inside UICollectionView How to expand collectionview cell to full screen Expand a cell to full screen when selected inside UICollectionView

但是无法理解如何在我的代码中应用它。 非常感谢！

我尝试了所有操作。但是照片只能在单元格中放大。单元格不是高档的。

override func collectionView(_ collectionView: UICollectionView, didHighlightItemAt indexPath: IndexPath) {
    UIView.animate(withDuration: 0.5) {
        if let cell = collectionView.cellForItem(at: indexPath) as? PhotosCollectionViewCell {
            UIView.animate(withDuration: 1,
                           delay: 0,
                           usingSpringWithDamping: 0.5,
                           initialSpringVelocity: 0,
                           options: [],
                           animations: {
                            var screenSize = UIScreen.main.bounds.size
                            let height = CGFloat(self.view.frame.size.height)
                            let width  = CGFloat(self.view.frame.size.width)
                            cell.photo?.frame = CGRect(x: 0, y: 0, width: width, height: height)
                            cell.photo?.bounds = CGRect(x: 0, y: 0, width: width, height: height)



            })
            cell.photo?.transform = .init(scaleX: 0.50, y: 0.50)
            cell.contentView.backgroundColor = UIColor(red: 0.95, green: 0.95, blue: 0.95, alpha: 1)
        }
    }
}
