OS X故事板:如何以编程方式显示窗口? [英] OS X storyboard: how to show a window programmatically?

问题描述

我正在创建OS X状态栏应用程序.

I am creating an OS X status bar application.

我正在努力实现以下目标:

I am trying to achieve the following:

• 应用程序开始不可见，带有菜单栏项
• 单击菜单栏项将显示主窗口
• 停用后，窗口被隐藏

因此，我试图在单击菜单项时以编程方式显示主窗口，但没有成功.

So I am trying to programmatically show the main window when the menu item is clicked, but with no success.

我的主窗口已选中隐藏停用" .隐藏后，我将无法使用代码再次使其可见.

My main window has "Hide on deactivate" checked. Once hidden, I cannot make it visible again using code.

这是我现在拥有的代码，但是它不起作用:

Here is the code I have for now, but it doesn't work:

@IBAction func menuClick(sender: AnyObject) {
    var mainWindow = NSStoryboard(name: "Main", bundle: nil)?.instantiateInitialController()
    mainWindow?.makeKeyAndOrderFront(self)
}

推荐答案

这是您以编程方式显示Windows的方法:

This is how you have to do to show your Windows programmatically:

import Cocoa

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {

     let mainWindow = NSWindow(contentRect: NSMakeRect(0, 0, NSScreen.mainScreen()!.frame.width/2, NSScreen.mainScreen()!.frame.height/2), styleMask: NSTitledWindowMask|NSResizableWindowMask|NSMiniaturizableWindowMask|NSClosableWindowMask, backing: NSBackingStoreType.Buffered, defer: false)

    func createNewWindow(){
        mainWindow.title = "Main Window"
        mainWindow.opaque = false
        mainWindow.center()
        mainWindow.hidesOnDeactivate = true
        mainWindow.movableByWindowBackground = true
        mainWindow.backgroundColor = NSColor(calibratedHue: 0, saturation: 0, brightness: 1, alpha: 1)
        mainWindow.makeKeyAndOrderFront(nil)
    }
    func applicationDidFinishLaunching(aNotification: NSNotification) {
        // lets get rid of the main window just closing it as soon as the app launches
        NSApplication.sharedApplication().windows.first!.close()
    }
    func applicationWillTerminate(aNotification: NSNotification) {
        // Insert code here to tear down your application
    }
    @IBAction func menuClick(sender: AnyObject) {
        createNewWindow()
    }
}

或者您可以创建一个可选的NSWindow var来存储您的窗口，然后按照以下步骤关闭它

or you can create an optional NSWindow var to store your window before you close it as follow

import Cocoa

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
    var defaultWindow:NSWindow?
    func applicationDidFinishLaunching(aNotification: NSNotification) {
        // lets get rid of the main window just closing it as soon as the app launches
        defaultWindow = NSApplication.sharedApplication().windows.first as? NSWindow
        if let defaultWindow = defaultWindow {
            defaultWindow.close()
        }
    }
    func applicationWillTerminate(aNotification: NSNotification) {
        // Insert code here to tear down your application
    }
    @IBAction func menuClick(sender: AnyObject) {
        if let defaultWindow = defaultWindow {
            defaultWindow.makeKeyAndOrderFront(nil)
        }
    }
}
