I have the simple and very standard task of getting the main menu
items to act on a document object in a multiple document app.
However, the menu and document are in different nib files.
How do you have your document nib setup? Is the File Owner a custom
subclass of NSWindowControler?
When I had to do something similar recently, I setup my controller as
a subclass of NSWindowController. Then I set this class as the File
Owner of the nib. Menu items were then connected to a sperate,
different controller instance in MainMenu.
When a menu action was fired, I went through these steps:
1) Get the main window from NSApp:
wndw = [NSApp mainWindow];
2) Get the controller from the window:
cntrlr = [wndw windowController].
3) Check the controller class and cast/call the appropriate function:
[cntrlr isKindOf:[MyWindowController class]]
Not sure this is the most cocoa way of doing things, but it worked for me.
