防止错误“放克"事件监视器OS X中发出声音 [英] Prevent error "funk" sound in event monitor OS X

问题描述

我正在迅速编写一个应用程序，该应用程序位于屏幕顶部的菜单栏中.我既需要全局事件监视器，也需要本地事件监视器，以在特定按键上打开弹出窗口.本地事件监视器没有问题，但是当用户从Finder之类的应用程序中敲击键盘命令(cmd + shift + 8)时，弹出窗口会打开，但也会播放mac错误"Funk"声音.有什么办法可以禁用此功能吗?也许应用可以通过某种方式来欣赏声音，或者将其注册为有效的键盘快捷键，从而使声音永不播放?

I'm writing an app in swift that lives in the menu bar at the top of the screen. I need both a global and local event monitor to open the popover on a specific key press. There is no problem with the local event monitor, but when the user hits the key command (cmd+shift+8) from inside an app like Finder, the popover opens but the mac error "Funk" sound is played as well. Is there any way I can disable this? Perhaps some way for the app to eat the sound, or register it as a valid keyboard shortcut so the sound is never played?

这是代码:

        NSEvent.addGlobalMonitorForEvents(matching: NSEventMask.keyDown, handler: {(event: NSEvent!) -> Void in
        if (event.keyCode == 28 && event.modifierFlags.contains(NSEventModifierFlags.command) && event.modifierFlags.contains(NSEventModifierFlags.shift)){
            self.togglePopover(sender: self)
        }
    });

    NSEvent.addLocalMonitorForEvents(matching: NSEventMask.keyDown, handler: {(event: NSEvent!) -> NSEvent? in
        if (event.keyCode == 28 && event.modifierFlags.contains(NSEventModifierFlags.command) && event.modifierFlags.contains(NSEventModifierFlags.shift)){
            self.togglePopover(sender: self)
        }
        return event
    });
