I have customized the contextual menu for my Cocoa application such that only certain items are visible. In spite of my customization, I found that the system adds a menu item -- "Add to iTunes as a spoken track".
I tried removing this item from the menu but somehow, I am unable to get the control. Is there a way this item can be removed, or do I have to write an AppleScript to disable the iTunes option under Keyboard Shortcuts? I hate doing that since I will then have to restore it for the user.
You can control the contents of these menus (system-wide) by using Preferences.
See System Preferences > Keyboard > Keyboard Shortcuts > Services > Text
In my experience, Apple's default items trigger off of the exact title of the menu. For example, I have a toy app with an NSMenu that I am creating entirely in code (no nib). I find that the View menu gets an extra item (for full screen) if I initialize it as follows:
NSMenu* viewMenu = [[NSMenu alloc]initWithTitle:#"View"];
However, if I put an extra space into the name, then Apple doesn't mess with it:
NSMenu* viewMenu = [[NSMenu alloc]initWithTitle:#"View "];
Is there a way this item can be removed, or do I have to write an AppleScript to disable the iTunes option under Keyboard Shortcuts?
Don't fight with The System; those Service items are supposed to appear on every context menu, as specified in the System Preferences. It even appears on the context menu of Safari which I'm using to view this post right now. Yes I agree that having "add to iTunes" enabled by default is a poor choice on the part of Apple, but that's life.
Maybe the user has his/her own service item s/he installed say as an Automator action. In that case the user probably doesn't want to have it removed.

I am currently creating a macOS menubar for an app without using any interface builder (no XIB/NIB files), just pure code. However I was expecting some items to be auto-generated during the start-up of the app. Items like "Start Dictation", "Emoji & Symbols" under Edit menu were existing as well as the "Enter Full Screen" menu item under the View Menu. But when it comes to Window Menu nothing was automatically generated, only the menu items I've set in the code. Do I have to enable some flags or options when instantiating a Window NSMenu so it automatically generates those items? I am new to macOS development so I feel like I am kind of lost. Thanks in advance.
The Window and Help menus are a little special in that they have their own NSApplication properties, so you will need to set them to your menus so that the system will know what they are.
For example, if you just create a window menu and add it to the main, all you will get are the items that you have provided. If you also set it as the application’s windowsMenu, in addition you will get all the stuff for moving, tab support, etc.
Setting NSApp’s helpMenu is similar, where a Spotlight menu item is added to the menu.
I am making my first OS X application in Xcode, and I have no idea how to make a specified keyboard shortcut trigger some code (e.g. ⌘ Cmd+ C/⌘ Cmd+V). All I can find online is keyboard shortcuts in Xcode itself.
Thanks in advance
This is usually setup for you automatically. The MainMenu.xib by default has an Edit menu with these shortcuts bound, activating [firstResponder copy:] and [firstResponder paste:]. The first responder is item currently having keyboard focus, or it's parent view if it doesn't answer to those actions, up to the window at the top level.
For new shortcuts, Apple recommends that you have menu items associated to all those. If you do, you can set the shortcut in the interface builder using the attributes inspector. You then ctrl-drag from the menu item to the object you want to send the action to, e.g. the app delegate. You will have to create the target method first obviously. You should also use bindings to control when the menu item is enabled or not.
It's not recommended, but if you want to do this programmatically, without a menu item, you override the
- (BOOL)performKeyEquivalent:(NSEvent *)theEvent
method of the view or window in question. It will be called if it's in the responder chain when the key is pressed, and you return YES to indicate you've handled the event.
I have a application with 2 windows (think like Twitter Timeline and mentions). For now I have been having the menus "Timeline ⌘1" and "Mentions ⌘2" in the "File" menu but this is kind of wrong. So I moved them to the "Windows" menu just by drag and drop.
When I open the application everything is nice, I can see both menu items unter the "Windows" menu. But then when I close for example the Mentions window the menu Item "Mentions ⌘2" disappears and I am not able to open this window anymore.
I have had a look at other applications and most of them have their Menu items to show the windows in the "Windows" menu and they don't disappear either after closing the windows. I am aware of the fact that Cocoa does soma magic with the "Window" menu item and it is quite ok in doing so (because I open some other windows which need to appear and disappear from there), but how can I make those two items kind of static so they don't disappear?
I finally found an answer, in order for them to not be handled by the Windows menu you need to call
[timelineViewWindow setExcludedFromWindowsMenu:YES];
[mentionsViewWindow setExcludedFromWindowsMenu:YES];
and after that add the Menu items to the Windows menu and they will not disappear anymore.
XCode works in mysterious ways (at least to me).
I simply want to create a Preference pane in my app. When I run my app, the stock menu bar comes up (Apple, MyApp, File, Edit...) and the "Preferences" menu item is grayed out. It makes sense since I haven't started playing with it.
How on earth do I add/remove/activate/inactivate menu items? I'm not talking about adding anything new, simply using what should be there.
Thanks in advance.
NSMenu has "Auto Enable Items" enabled by default. That means if the menu item does not have it's action message hooked up, it will appear grayed out. So in your case, you would simply set the Preferences menu item's "Sent Action" to whatever action shows your preferences window. This can be hooked to some sort of showPreferencesWindow: method of your AppDelegate, or directly to the showWindow: method of a window controller.
To dynamically enable/disable menu items the best way is to implement the NSUserInterfaceItemValidation protocol which is excellently documented here
Edit: Your app's menu bar items live in the MainMenu.xib file. The menu bar appears as a "Main Menu" object on the left hand side (if you're using Xcode 4) Simply click on the items to modify them, and you can Ctrl+drag connections to and from them like any UI object.
When you press the keys for an NSMenuItem keyboard shortcut on Mac, the menu itself highlights to indicate that an action in that menu has been activated.
If you are not familiar with the effect try it now by selecting some text and while pressing CMD-C, watch the Edit menu. It will flash blue to indicate you activated a shortcut for an item in that menu.
I want to achieve the same effect programmatically, preferably without faking the keyboard entry. Thanks for your time.
Use the Accessibility framework. Find the menu item and send it an AXPress action.
