我正在尝试监听全局键盘事件，并让我的应用程序在检测到某些按键时执行特定的操作。为此，我想使用：

class ViewController: NSViewController {

    override func viewDidLoad() {

        super.viewDidLoad()
        //Add keyboard event listener.
        NSEvent.addGlobalMonitorForEvents(matching: .keyDown, handler:
        {
            print("key down!");
            print($0.keyCode);
        });
    }
}

我正在以这种方式检查 appDelegate.swift 中的可访问权限：

func applicationDidFinishLaunching(_ aNotification: Notification) {
    // Insert code here to initialize your application
    //check if the process is trusted for accessibility. This is important for us to listen for keyboard events system wide.
    let checkOptPrompt = kAXTrustedCheckOptionPrompt.takeUnretainedValue() as NSString

    let options = [checkOptPrompt: true]
    let isAppTrusted = AXIsProcessTrustedWithOptions(options as CFDictionary?);
    if(isAppTrusted != true) …
