How i can get the Application Menu in Cocoa

Question

How can I get the NSMenu or NSMenuItem for the application menu (the one in the menu bar next to the apple menu). It seems to be automatically created and independent from the NSMenu I set via NSApplication setMainMenu.

By the way: I'm building my complete application without Xcode, so please no InterfaceBuilder tips.

PS: MacOSX 10.5

Answer 1

Without IB, you can access the menu using the NSApplication's mainMenu:

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

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

Though this is 5 years old question... I like to share how to make it.

In my experience in OS X 10.11 (El Capitan) with Xcode 7.1, it's not hard to replicate that application menu. It seems Apple removed all the weird limitations.

Note: This code is updated for Swift 3, and tested only in macOS Sierra (10.12.1).

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()

Anyway, it is not being generated automatically, and I had to set them all up myself. I am not sure whether there is another way to do this or not.

my two cents for Swift 5.0

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)
        }
    }
}

so You can also enable it:

....

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

制作没有Xcode或IB的Cocoa应用程序对我来说是自虐的，但对他自己来说却是受虐狂的...尝试这个： [[[NSApp mainMenu] itemAtIndex: 0] submenu] 。
