在添加了LinkPresentation视图的堆栈上重用时，单元格不显示元素

如何解决在添加了LinkPresentation视图的堆栈上重用时，单元格不显示元素

在介绍用于元数据

的LinkView之前，我有一个自定义视图，就像魅力一样工作。

我介绍了LinkView之后，由于它位于stackView中，因此在准备可重用时必须从超级视图中删除linkView（不确定为什么尝试重绘布局，但似乎不适用于LinkView），向下滚动时会出现问题元素，似乎数据在某些时候丢失了，奇怪的是，它仅在包含linkView项的可重用元素中发生，这是否有原因吗？我该如何解决？

这是我用于单元格的代码

final class TimeLineTableViewCell: UITableViewCell {
    var cornerRadius: CGFloat = 6
    var shadowOffsetWidth = 0
    var shadowOffsetHeight = 3
    var shadowColor: UIColor = .gray
    var shadowOpacity: Float = 0.3
    
    lazy var containerView: UIView = {
        let view = UIView()
        view.translatesAutoresizingMaskIntoConstraints = false
        view.backgroundColor = .white
        view.addSubview(stackViewContainer)
        
        let shadowPath = UIBezierPath(roundedRect: bounds,cornerRadius: cornerRadius)
        view.layer.cornerRadius = cornerRadius
        view.clipsToBounds = true
        view.layer.masksToBounds = false
        view.layer.shadowColor = shadowColor.cgColor
        view.layer.shadowOffset = CGSize(width: shadowOffsetWidth,height: shadowOffsetHeight);
        view.layer.shadowOpacity = shadowOpacity
        view.layer.shadowPath = shadowPath.cgPath
        return view
    }()
    
    lazy var stackViewContainer: UIStackView = {
        let stack = UIStackView()
        stack.axis = .horizontal
        stack.alignment = .center
        stack.translatesAutoresizingMaskIntoConstraints = false
        stack.distribution = .fill
        stack.spacing = 10.0
        stack.addArrangedSubview(profileImage)
        stack.addArrangedSubview(stackViewDataHolder)
        return stack
    }()
    
    lazy var profileImage: UIImageView = {
        let image = UIImage()
        let imageView = UIImageView(image: image)
        imageView.translatesAutoresizingMaskIntoConstraints = false
        imageView.contentMode = .scaleAspectFit
        return imageView
    }()
    
    lazy var userName: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.numberOfLines = 0
        return label
    }()
    
    lazy var tweetInfo: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.numberOfLines = 0
        return label
    }()
    
    lazy var tweetText: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.numberOfLines = 0
        return label
    }()
    
    lazy var linkView: LPLinkView = {
        let viewer = LPLinkView(frame: CGRect(origin: .zero,size: .init(width: 200,height: 20)))
        viewer.translatesAutoresizingMaskIntoConstraints = false
        return viewer
    }()
    
    lazy var stackViewDataHolder: UIStackView = {
        let stack = UIStackView()
        stack.axis = .vertical
        stack.translatesAutoresizingMaskIntoConstraints = false
        stack.distribution = .fillProportionally
        stack.addArrangedSubview(userName)
        stack.addArrangedSubview(tweetInfo)
        stack.addArrangedSubview(tweetText)
        return stack
    }()
    
    override init(style: UITableViewCell.CellStyle,reuseIdentifier: String?) {
        super.init(style: style,reuseIdentifier: reuseIdentifier)
        commonInit()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
        commonInit()
    }
    
    override func prepareForReuse() {
        linkView.removeFromSuperview()
    }
    
    func configure(viewModel: ProfileTweetViewModel) {
        tweetInfo.configure(model: viewModel.tweetInfo)
        userName.configure(model: viewModel.name)
        tweetText.configure(model: viewModel.tweet)
        if let metadata = viewModel.linkData {
            linkView = LPLinkView(metadata: metadata)
            stackViewDataHolder.addArrangedSubview(linkView)
            //Tried almost all layoyt options but seems a previous view can't be updated since frame is wrong
        }
        
        if let url = viewModel.profilePic {
            profileImage.downloadImage(from: url)
        }
    }
}

private extension TimeLineTableViewCell {
    struct Metrics {
        static let lateralPadding: CGFloat = 8
    }
    
    func constraints() {
        NSLayoutConstraint.activate([
            stackViewContainer.topAnchor.constraint(equalTo: containerView.topAnchor,constant: Metrics.lateralPadding),stackViewContainer.bottomAnchor.constraint(equalTo: containerView.bottomAnchor,constant: -Metrics.lateralPadding),stackViewContainer.leadingAnchor.constraint(equalTo: containerView.leadingAnchor,stackViewContainer.trailingAnchor.constraint(equalTo: containerView.trailingAnchor,profileImage.heightAnchor.constraint(equalTo: profileImage.widthAnchor,multiplier: 1.0),profileImage.widthAnchor.constraint(equalToConstant: 50.0),])
    }
    
    func commonInit() {
        addSubview(containerView)
        backgroundColor = .clear
        
        NSLayoutConstraint.activate([
            containerView.topAnchor.constraint(equalTo: topAnchor),containerView.leadingAnchor.constraint(equalTo: leadingAnchor,constant: 4),containerView.trailingAnchor.constraint(equalTo: trailingAnchor,constant: -4),containerView.bottomAnchor.constraint(equalTo: bottomAnchor,])
        
        constraints()
    }
    
    
}

谢谢您的时间。

解决方法

问题与stackView中的.fillProportionally有关 由于linkView有时会以0高度进行渲染，因此我只需要在stackView中使用.fill属性即可完整显示它
