如何获取应用程序菜单的 NSMenu 或 NSMenuItem（在苹果菜单旁边的菜单栏中）。它似乎是自动创建的，并且独立于我通过 NSApplication setMainMenu 设置的 NSMenu。

顺便说一句：我正在构建没有 Xcode 的完整应用程序，所以请不要使用 InterfaceBuilder 提示。

PS：MacOSX 10.5

如果没有 IB，您可以使用 NSApplication 的 mainMenu 访问菜单：

NSMenu *mainMenu = [[NSApplication sharedApplication] mainMenu];
NSMenu *appMenu = [[mainMenu itemAtIndex:0] submenu];

for (NSMenuItem *item in [appMenu itemArray]) {
    NSLog(@"%@", [item title]);
}

虽然这是 5 年前的问题......我喜欢分享如何制作它。

根据我在使用 Xcode 7.1 的 OS X 10.11 (El Capitan) 的经验，复制该应用程序菜单并不难。苹果似乎消除了所有奇怪的限制。

注意：此代码针对 Swift 3 进行了更新，并且仅在 macOS Sierra (10.12.1) 中进行了测试。

import Cocoa

/// You SHOULD NOT use `@NSApplicationMain` 
/// to make your custom menu to work.
class AppDelegate: NSObject, NSApplicationDelegate {
    func applicationDidFinishLaunching(_ aNotification: Notification) {}
    func applicationWillTerminate(_ aNotification: Notification) {}
}

func makeMainMenu() -> NSMenu {
    let mainMenu            = NSMenu() // `title` really doesn't matter.
    let mainAppMenuItem     = NSMenuItem(title: "Application", action: nil, keyEquivalent: "") // `title` really doesn't matter.
    let mainFileMenuItem    = NSMenuItem(title: "File", action: nil, keyEquivalent: "")
    mainMenu.addItem(mainAppMenuItem)
    mainMenu.addItem(mainFileMenuItem)

    let appMenu             = NSMenu() // `title` really doesn't matter.
    mainAppMenuItem.submenu = appMenu

    let appServicesMenu     = NSMenu()
    NSApp.servicesMenu      = appServicesMenu

    appMenu.addItem(withTitle: "About Me", action: nil, keyEquivalent: "")
    appMenu.addItem(NSMenuItem.separator())
    appMenu.addItem(withTitle: "Preferences...", action: nil, keyEquivalent: ",")
    appMenu.addItem(NSMenuItem.separator())
    appMenu.addItem(withTitle: "Hide Me", action: #selector(NSApplication.hide(_:)), keyEquivalent: "h")
    appMenu.addItem({ () -> NSMenuItem in
        let m = NSMenuItem(title: "Hide Others", action: #selector(NSApplication.hideOtherApplications(_:)), keyEquivalent: "h")
        m.keyEquivalentModifierMask = [.command, .option]
        return m
        }())
    appMenu.addItem(withTitle: "Show All", action: #selector(NSApplication.unhideAllApplications(_:)), keyEquivalent: "")

    appMenu.addItem(NSMenuItem.separator())
    appMenu.addItem(withTitle: "Services", action: nil, keyEquivalent: "").submenu = appServicesMenu
    appMenu.addItem(NSMenuItem.separator())
    appMenu.addItem(withTitle: "Quit Me", action: #selector(NSApplication.terminate(_:)), keyEquivalent: "q")

    let fileMenu = NSMenu(title: "File")
    mainFileMenuItem.submenu = fileMenu
    fileMenu.addItem(withTitle: "New...", action: #selector(NSDocumentController.newDocument(_:)), keyEquivalent: "n")

    return mainMenu
}

let del = AppDelegate()
/// Setting main menu MUST be done before you setting app delegate.
/// I don't know why.
NSApplication.shared().mainMenu = makeMainMenu()
NSApplication.shared().delegate = del
NSApplication.shared().run()

无论如何，它不是自动生成的，我必须自己设置它们。我不确定是否有其他方法可以做到这一点。

Swift 5.0 我的两分钱

private final func manageMenus(){
    let  mainMenu =  NSApplication.shared.mainMenu

    if let editMenu = mainMenu?.item(at: 1)?.submenu{
        for item in editMenu.items{
            print(item.title)
        }
    }
}

所以你也可以启用它：

……

  for item in editMenu.items{
       item.isEnabled = true
   }

制作一个没有 Xcode 或 IB 的 Cocoa 应用程序对我来说听起来很自虐，但对每个人来说都是他自己的......试试这个：[[[NSApp mainMenu] itemAtIndex: 0] submenu]。
