Macos 无法在Swift OS X中接收NSWorkspaceDidWakeNotification

我正在制作一个macOS应用程序，在这个应用程序中，当计算机醒来、睡着、醒来时，有必要做一些事情，但我无法让侦听器工作。我觉得我什么都试过了。在

AppDelegate.swift

函数

applicationdFinishLaunching

的内部，我得到了：

NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "sleepListener", name: NSWorkspaceWillSleepNotification, object: nil)
NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "wakeUpListener", name: NSWorkspaceDidWakeNotification, object: nil)

在

AppDelegate.swift

内部，但在功能

applicationdFinishLaunching

外部，我有：

func sleepListener(aNotification : NSNotification) {
    print("Sleep Listening");
}

func wakeUpListener(aNotification : NSNotification) {
    print("Wake Up Listening");
}

我尝试了多种不同的方法来解决这个问题。我尝试在

NSNotificationCenter.defaultCenter（）

上侦听，尝试将选择器更改为

sleepListener:

和

wakeUpListener:

，尝试从两个函数中删除参数，但迄今为止没有任何效果。真正有趣的是，我还有另外两个监听器可以很好地工作，

nsworkspacesscreensidsleepnotification

和

nsworkspacesscreensidwakenotification

，通过使用

NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "screenSleepListener", name: NSWorkspaceScreensDidSleepNotification, object: nil)

及

引用函数

func screenSleepListener() {
    print("Screen Sleep Listening");
}

func screenWakeUpListener() {
    print("Screen Wake Up Listening");
}

那么，这是不是我做错了什么？这是我应该提交错误报告的事情吗？如果其他人可以在一个文件中运行此代码，让他们的显示器和计算机进入睡眠状态，并查看是否出现相同的错误，这将非常有帮助。如果有人知道我到底做错了什么，那就更好了

提前谢谢你

我看到这篇文章是很久以前写的

从你的帖子中，我得到的印象是你按错误的顺序做了两次排列

    NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "sleepListener", name: NSWorkspaceWillSleepNotification, object: nil)
    NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "wakeUpListener", name: NSWorkspaceDidWakeNotification, object: nil)
func sleepListener() {
    print("Sleep Listening");
}

func wakeUpListener() {
    print("Wake Up Listening");
}

或

NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "sleepListener:", name: NSWorkspaceWillSleepNotification, object: nil)
        NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "wakeUpListener:", name: NSWorkspaceDidWakeNotification, object: nil)

func sleepListener(aNotification : NSNotification) {
    print("Sleep Listening");
}

func wakeUpListener(aNotification : NSNotification) {
    print("Wake Up Listening");
}

甚至更好

NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "sleepListener:", name: NSWorkspaceWillSleepNotification, object: nil)

NSWorkspace.sharedWorkspace().notificationCenter.addObserver(self, selector: "sleepListener:", name: NSWorkspaceDidWakeNotification, object: nil)

 func sleepListener(aNotification : NSNotification) {
            if aNotification.name == NSWorkspaceWillSleepNotification{
                print("Going to sleep")
            }else if aNotification.name == NSWorkspaceDidWakeNotification{
                print("Woke up")
            }else{
                print("Some other event other than the first two")
            }
        }

在哪里添加这些观察者也很重要。对我来说，他们都在应用程序代理中，都在工作
