覆盖UILabel的布局以添加具有手势处理的子视图

let containerView = UIView()
containerView.backgroundColor = UIColor.clear
label.addSubview(containerView)

containerView.translatesAutoresizingMaskIntoConstraints = false
containerView.topAnchor.constraint(equalTo: label.topAnchor).isActive = true
containerView.leadingAnchor.constraint(equalTo: label.leadingAnchor).isActive = true
containerView.trailingAnchor.constraint(equalTo: label.trailingAnchor).isActive = true
containerView.bottomAnchor.constraint(equalTo: label.bottomAnchor).isActive = true

let gestureView = UIView()
gestureView.backgroundColor = UIColor.red
containerView.addSubview(gestureView)

gestureView.translatesAutoresizingMaskIntoConstraints = false
gestureView.topAnchor.constraint(equalTo: containerView.topAnchor).isActive = true
gestureView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor).isActive = true
gestureView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor).isActive = true
gestureView.bottomAnchor.constraint(equalTo: containerView.bottomAnchor).isActive = true

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTapGesture(_:)))
gestureView.addGestureRecognizer(tapGesture)

@objc func handleTapGesture(_ gesture: UITapGestureRecognizer) {
    // 处理手势操作
}
