swift - 检测 NSStatusItem 上的左键和右键单击事件 (Swift)

Question

我正在构建一个状态栏应用程序，并希望根据用户单击向左还是向右来调用不同的操作。这是我到目前为止所拥有的:

var statusItem = NSStatusBar.system().statusItem(withLength: -1)
statusItem.action = #selector(AppDelegate.doSomeAction(sender:))

let leftClick = NSEventMask.leftMouseDown
let rightClick = NSEventMask.rightMouseDown

statusItem.button?.sendAction(on: leftClick)
statusItem.button?.sendAction(on: rightClick)

func doSomeAction(sender: NSStatusItem) {
    print("hello world")
}

我的函数没有被调用，我找不到原因。我感谢任何帮助!

你尝试过吗:

button.sendAction(on: [.leftMouseUp, .rightMouseUp])

然后看看在doSomeAction()函数中按下了哪个鼠标按钮？

所以它看起来像......

let statusItem = NSStatusBar.system().statusItem(withLength: NSSquareStatusItemLength)

func applicationDidFinishLaunching(_ aNotification: Notification) {

    if let button = statusItem.button {
        button.action = #selector(self.doSomeAction(sender:))
        button.sendAction(on: [.leftMouseUp, .rightMouseUp])
    }

}

func doSomeAction(sender: NSStatusItem) {

    let event = NSApp.currentEvent!

    if event.type == NSEvent.EventType.rightMouseUp {
        // Right button click
    } else {
        // Left button click
    }

}

感谢 @dbrownjave 注意到 Swift 4 中从 NSEventType.rightMouseUp 到 NSEvent.EventType.rightMouseUp 的更改。
