方法一：

func applicationShouldHandleReopen(sender: NSApplication,hasVisibleWindows
flag: Bool) -> Bool {
    if !flag{
        let sb = nsstoryboard(name: "Main",bundle: nil)
        let controller = sb?.instantiateInitialController() as
NSWindowController
        controller.window?.makeKeyAndOrderFront(self)
        self.window = controller.window
    }
    return true 
}

方法二：

func applicationShouldHandleReopen(sender: NSApplication,hasVisibleWindows
    flag: Bool) -> Bool {
        if !flag{
            for window in sender.windows{
                if let w = window as? NSWindow{
                    w.makeKeyAndOrderFront(self)
                }
            }
     }
    return true 
}

方法三：

var mainWindow: NSWindow!
func applicationDidFinishLaunching(aNotification: NSNotification) {
        mainWindow = NSApplication.sharedApplication().windows[0] as! NSWindow
}
func applicationShouldHandleReopen(sender: NSApplication,hasVisibleWindows
    flag: Bool) -> Bool {
        if !flag{
            mainWindow.makeKeyAndOrderFront(nil)
        }
    return true 
}
