问题描述

限时删除!!

我的项目中有一个NSMenuItem:

I have a NSMenuItem in my project:

var statusBar = NSStatusBar.systemStatusBar()
var statusItem : NSStatusItem = NSStatusItem()
var menuItem : NSMenuItem = NSMenuItem()
var mainMenu = NSMenu()

override func viewDidLoad() {
    super.viewDidLoad()

    menuItem.title = "Holidays"
    menuItem.action = Selector("setWindowVisible:")
    menuItem.target = nil
    menuItem.keyEquivalent = "M"
    menuItem.enabled = true
    mainMenu.addItem(menuItem)

    statusItem = statusBar.statusItemWithLength(-1)
    statusItem.menu = mainMenu
    statusItem.title = statusItem.menu?.itemAtIndex(0)?.title

}

它将项目添加到菜单,但未启用:

It adds the item to menu, but it isn't enabled:

选择器也有效,函数setWindowVisible属于同一类:

And the selector is valid too, the function setWindowVisible exists in the same class:

func setWindowVisible(sender : AnyObject?) {
    self.window!.orderFront(self)
}

推荐答案

目标必须是self而不是nil.

The target needs to be self instead of nil.

menuItem.target = self
