**斯威夫特 *

let contextMenu = UIMenuController.shared
    contextMenu.menuItems = [
    UIMenuItem(title: "test", action: #selector(testclicked)),
    UIMenuItem(title: "test 1", action: #selector(test1clicked)),
    UIMenuItem(title: "test2", action: #selector(test2clicked)),
    UIMenuItem(title: "test3", action: #selector(test3clicked))
    ]
    contextMenu.showMenu(from: self.view, rect: CGRect(x: 100, y: 190, width: 100, height: 20))
