Get index of NSMenuItem (sender) in parent menu

I'm having a NSMenu (application dock menu) and several items in it with the same action.

How can I figure out the index of the sender item (the one triggering the action) within its container menu? (I'm not interesting in the title, since that might be a duplicate)

That's what I tried, but it keeps returning 0 (zero).

- (void)myAction:(id)sender
{
    NSMenuItem* mi = (NSMenuItem*)sender;

    int index = [[[mi parentItem] submenu] indexOfItem:mi];

    NSLog(@"Clicked item with index : %d",index);
}

Any ideas? (Is there any better approach to achieve the very same thing?)

Lookup the id of the sender in it's parent menu. A menu contains an array of it's menu items.

int indexOfMenuItem = [sender.menu.itemArray indexOfObject:sender];

indexOfObject is a method of NSArray.

You could use the menu items' representedObject to store a reference to some object in your app. In your case, you would probably use the document that the menu item refers to:

[aMenuItem setRepresentedObject:yourDocument];

You could then access the object in the action like so:

- (void)myAction:(id)sender
{
    NSMenuItem* mi = (NSMenuItem*)sender;
    YourDocument* doc = (YourDocument*)[sender representedObject];
    //do something with doc
}
