如何在Mac上实现VoiceOver的accessibilityCustomActions？

class MyAccessibilityDelegate: NSObject {
    override func accessibilityCustomActions() -> [NSAccessibilityCustomAction]? {
        // 返回包含自定义操作的数组
        let action1 = NSAccessibilityCustomAction(name: "Action 1", target: self, selector: #selector(action1Handler))
        let action2 = NSAccessibilityCustomAction(name: "Action 2", target: self, selector: #selector(action2Handler))
        return [action1, action2]
    }
    
    @objc func action1Handler() {
        // 处理自定义操作1的逻辑
    }
    
    @objc func action2Handler() {
        // 处理自定义操作2的逻辑
    }
}

let myView = MyCustomView()
myView.accessibilityDelegate = MyAccessibilityDelegate()
