单击statusItem时如何调用函数/动作？

Question

I have this code that opens up a popover element at the "sender" location, ie the button that was pressed. How can I make this function call when a statusItem is clicked, so that the popover comes down from the status/menu bar?

@IBAction func togglePopover(sender: AnyObject) {
    if !(popoverIsOpen) {
        myPopover.showRelativeToRect(sender.bounds, ofView: popoverButton, preferredEdge: NSRectEdge(3))
        popoverIsOpen = true
    }
    else {
        myPopover.close()
        popoverIsOpen = false
    }
}

I am currently using NSPopover and NSStatusItem .

edit: The changelog for Xcode 6 beta 4 added NSStatusItem.button and softly deprecated the previous form of calls like NSStatusItem.action , NSStatusItem.title , NSStatusItem.target , etc.

The documentation now reads

NSStatusItem.button

The button that is displayed in the status bar. This is created automatically on the creation of the StatusItem. Behavior customization for the button, such as image, target/action, tooltip, can be set with this property.

I was able to reach an implementation shown below, using the new NSStatusBarButton visual representation of an NSStatusBarItem. In this example, my .xib file has the NSPopover element already connected to a view, which isn't shown here.

@IBOutlet weak var myPopover: NSPopover!
var statusBar: NSStatusItem!
var popoverIsOpen = false

@IBAction func togglePopover(sender: AnyObject) {
    if !(popoverIsOpen) {
        myPopover.showRelativeToRect(sender.bounds, ofView: statusBar.button, preferredEdge: NSRectEdge(3))
        popoverIsOpen = true
    }
    else {
        myPopover.close()
        popoverIsOpen = false
    }
}

func applicationDidFinishLaunching(aNotification: NSNotification?) {
    //initialize menu bar icon
    statusBar = NSStatusBar.systemStatusBar().statusItemWithLength(CGFloat(48))
    statusBar.button.title = "Your App Title"
    statusBar.button.appearsDisabled = false
    statusBar.button.action = Selector("togglePopover:")
    statusBar.button.target = self
}
