swift - removeFromSuperView禁用交互

我有一个UICollectionView，它基本上是一个聊天日志。我在一些单元格中有一个imageView，并添加了在点击时将图像扩展到全屏的功能。

///
ChatLogMessageCell.swift


/**
*
* I add the target to the UIButton with an image as a background
*/

messageImage.addTarget(self, action: #selector(fullscreenImage), for: .touchUpInside)

/*
* Full screen code
*/
@objc func fullscreenImage() {

    if let chatlog = parentViewController as? ChatLogController {
        let imageScroll = UIScrollView()
        imageScroll.delegate = self
        imageScroll.minimumZoomScale = 1.0
        imageScroll.maximumZoomScale = 5.0
        imageScroll.frame = UIScreen.main.bounds

        let newImageView = UIImageView(image: messageImage.backgroundImage(for: .normal))
        newImageView.frame = UIScreen.main.bounds
        newImageView.backgroundColor = .black
        newImageView.contentMode = .scaleAspectFit
        newImageView.isUserInteractionEnabled = true
        imageScroll.addSubview(newImageView)

        chatlog.view.addSubview(imageScroll)
        chatlog.navigationController?.isNavigationBarHidden = true
        chatlog.tabBarController?.tabBar.isHidden = true
        let tap = UITapGestureRecognizer(target: self, action: #selector(dismissFullscreenImage))
            newImageView.addGestureRecognizer(tap)
    }

}

@objc func dismissFullscreenImage(_ sender: UITapGestureRecognizer) {
        if let chatlog = parentViewController as? ChatLogController {
            chatlog.navigationController?.isNavigationBarHidden = false
            chatlog.tabBarController?.tabBar.isHidden = false
            sender.view?.removeFromSuperview()
        }
    }

删除全屏图像后，ChatLogController不再可交互。我无法在图像上滚动或重新进入全屏模式。这里缺少什么？我只想关闭全屏图像，允许用户选择另一个图像或只是滚动信息。

最佳答案

在这里删除imageView

sender.view?.removeFromSuperview()

当你需要像

sender.view?.superview?.removeFromSuperview()
