Can a variable be passed into an NSMenu action?

I am dynamically building menu's based on an array and there is a sub-menu is linked to an IBAction which opens a folder in Finder. The folder it opens is based on a property of the object in my initial array.

Is there a way of linked the NSMenuItem action to the IBAction and passing in this directory variable as I am dynamically creating this array?

OR should I be going into the IBAction and resolving the directory by referencing the NSMenuItem with against array?

e.g.

person = [[Person alloc] init];
// person is assigned
subMenu = [[NSMenu alloc] init];
[subMenu addItemWithTitle:@"Open folder" action:@selector(openDirectory:person.directory) keyEquivalent:@""];
Solution

  • An action only takes a "(id) sender" parameter, where the object that called the action is supposed to be sent.

    But if your action method lives in some Objective C object (and not a singleton or whatever), you can easily reference that object's properties from your action.

    Hopefully this is clear to you or if not, show a bit of your IBAction code and tell us where it lives and how it's declared.
