在 UITableView Cell 中放置阴影在 Swift 中不起作用

Question

我的项目没有使用故事板，因为它使用的是 CleanSwift 架构。每个视图都是以编程方式构建的。这是我的 table 单元格 class.

class LiveScoreCell: UITableViewCell {

var data: LiveScores.Data? {
    didSet {
        leagueLogo.setImage(data?.leagueLogo)
    }
}

var container: UIView = {
    let view = UIView()
    view.backgroundColor = .white
    view.layer.cornerRadius = 10
    view.layer.shadowColor = UIColor.black.cgColor
    view.layer.shadowOffset = .zero
    view.layer.shadowOpacity = 0.6
    view.layer.shadowRadius = 10
    view.layer.shadowPath = UIBezierPath(rect: view.bounds).cgPath
    view.layer.borderWidth = 1
    view.translatesAutoresizingMaskIntoConstraints = false
    return view
}()
    
var leagueLogo: UIImageView = {
    let imgView = UIImageView()
    imgView.translatesAutoresizingMaskIntoConstraints = false
    return imgView
}()

override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)
    selectionStyle = .none
    setupViews()
}

required init?(coder: NSCoder) {
    super.init(coder: coder)
    selectionStyle = .none
    setupViews()
}

override func prepareForReuse() {
    super.prepareForReuse()
}


func setupViews() {
    addSubview(container)
    container.topAnchor.constraint(equalTo: self.topAnchor, constant: 8).isActive = true
    container.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: -8).isActive = true
    container.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 8).isActive = true
    container.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -8).isActive = true
    
    addSubview(leagueLogo)
    leagueLogo.topAnchor.constraint(equalTo: container.topAnchor, constant: 8).isActive = true
    leagueLogo.leadingAnchor.constraint(equalTo: container.leadingAnchor, constant: 8).isActive = true
    leagueLogo.widthAnchor.constraint(equalToConstant: 26).isActive = true
    leagueLogo.heightAnchor.constraint(equalToConstant: 26).isActive = true
}
    
}

结果是..

只有边界涉及..知道为什么会这样吗？

Answer 1

截至本行

view.layer.shadowPath = UIBezierPath(rect: view.bounds).cgPath

当边界为零时运行，所以让它在里面

override func layoutSubviews() {
  super.layoutSubviews()
  container.layer.shadowPath = UIBezierPath(rect: container.bounds).cgPath
}

在 UITableView Cell 中放置阴影在 Swift 中不起作用

Dropping shadow inside UITableView Cell doesn't work in Swift
