Ios 从集合视图单元格创建的UIView的旋转和大小调整

我有一个集合视图，点击它的单元uiview创建时，单元坐标被转换为superview。接下来，当新创建的uiview旋转90度时，我需要将创建的uiview调整为屏幕大小：

let coord = collectionView.layoutAttributesForItem(at: indexPath)
let cellFrameInSuperview:CGRect! = collectionView.convert(coord!.frame, to: self.view)
let imageViewDummy = UIView(frame: CGRect(x: (cellFrameInSuperview?.origin.x)!, y: (cellFrameInSuperview?.origin.y)!, width: cell.videoContainer.coverImageView.frame.size.width, height: cell.videoContainer.coverImageView.frame.size.height))

UIView.animate(withDuration: 3, animations: {
     var transform = CGAffineTransform.identity
     transform = transform.rotated(by: CGFloat(Double.pi / 2))
     imageViewDummy.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.height, height: UIScreen.main.bounds.width)
     imageViewDummy.transform = transform
})

但在动画之后，视图被错误地放置。它应该适合全屏

更新：

工作代码：

 UIView.animate(withDuration: 3, animations: {
            imageViewDummy.center = CGPoint(x: imageViewDummy.frame.size.height / 2, y: imageViewDummy.frame.size.width / 2)
            var transform = CGAffineTransform.identity
            transform = transform.rotated(by: CGFloat(Double.pi / 2))
            imageViewDummy.transform = transform
            imageViewDummy.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height)
        }, completion: {(result: Bool) in

        })

你能分享你得到的结果的图片吗？请找到屏幕截图并且自动调整大小在IBI中被禁用。请看，为什么不尝试创建imageViewDummy以将原点坐标设置为0,0？我的意思是：

让imageViewDummy=UIView（frame:CGRect（x:0.0，y:0.0，width:cell.videoContainer.coverImageView.frame.size.width，height:cell.videoContainer.coverImageView.frame.size.height））
