1、使用

       let menu = YXOperationPanel(style: .all)
        menu.delegate = self
        view.addSubview(menu)
        let itemWH = UIScreen.main.bounds.size.width - 100
        NSLayoutConstraint.activate([
            menu.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            menu.topAnchor.constraint(equalTo: view.topAnchor, constant: 100),
            menu.widthAnchor.constraint(equalToConstant: itemWH),
            menu.heightAnchor.constraint(equalToConstant: itemWH)
        ])
   
        let menu2 = YXOperationPanel(style: .both)
        menu2.delegate = self
        view.addSubview(menu2)
        NSLayoutConstraint.activate([
            menu2.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            menu2.topAnchor.constraint(equalTo: menu.bottomAnchor, constant: 50),
            menu2.widthAnchor.constraint(equalToConstant: itemWH),
            menu2.heightAnchor.constraint(equalToConstant: itemWH/2)
        ])
