多行UILabel底部在滚动后被切断，UITableViewCell -> UIStackView -> UILabel

class CustomTableViewCell: UITableViewCell {
    let label = UILabel()

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        
        label.numberOfLines = 0
        label.translatesAutoresizingMaskIntoConstraints = false
        contentView.addSubview(label)
        
        NSLayoutConstraint.activate([
            label.topAnchor.constraint(equalTo: contentView.topAnchor),
            label.bottomAnchor.constraint(equalTo: contentView.bottomAnchor),
            label.leadingAnchor.constraint(equalTo: contentView.leadingAnchor),
            label.trailingAnchor.constraint(equalTo: contentView.trailingAnchor)
        ])
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    override var intrinsicContentSize: CGSize {
        let size = label.intrinsicContentSize
        return CGSize(width: size.width, height: size.height + 16) // 添加额外的高度，以避免底部被切断
    }
}
