禁用整个UIView

func disableView(_ view: UIView) {
    view.isUserInteractionEnabled = false
    view.subviews.forEach { disableView($0) }
}

let view = UIView()
disableView(view)

let overlayView = UIView(frame: view.bounds)
overlayView.backgroundColor = UIColor.clear
overlayView.isUserInteractionEnabled = true

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap))
overlayView.addGestureRecognizer(tapGesture)

view.addSubview(overlayView)

@objc func handleTap(sender: UITapGestureRecognizer) {
    // Do nothing
}
