swift - 在 MacOS 上的 Swift 中使用 CGEvent.tapCreate 捕获鼠标事件

Question

我是新手 Swift 编码器，试图捕捉鼠标事件和键盘事件。看来我只做后者。主要目标是允许使用 Magic Mouse 2 进行“点击点击”并避免其响亮的点击声。

https://github.com/creasty/Keyboard/blob/master/keyboard/AppDelegate.swift上的完整工作示例

        let eventMask = 
            (1 << CGEventType.keyDown.rawValue) | 
            (1 << CGEventType.keyUp.rawValue) | 
            (1 << CGEventType.leftMouseDown.rawValue) | 
            (1 << CGEventType.leftMouseUp.rawValue)

        guard let eventTap = CGEvent.tapCreate(
            tap: .cghidEventTap,
            place: .headInsertEventTap,
            options: .defaultTap,
            eventsOfInterest: CGEventMask(eventMask),
            callback: appComponent.eventTapCallback,
            userInfo: nil
        ) else {
            fatalError("Failed to create event tap")
        }

键盘按下可以捕捉到，但对鼠标点击没有反应。请指教。谢谢。
