How on earth to I communicate with an object that has been
instantiated by Interface Builder???
Declare an IBOutlet pointer connecting an instantiated class to the
instantiated object. Then read the instantiated class's header file
into IB, which is normally done automatically, but you may have to
do it manually if you're working on a framework.
...but note that this is not how James would solve the concrete
problem mentioned in the original message.
In a document based application you don't have "the document", you
have any number of documents. The AppDelegate doesn't just want a
reference to any document, it's looking for some specific document.
Typically that would be the document associated with the "main
window" (check the documentation for more on what "main" and "key"
window is in Cocoa). You could find that document like this:
NSApp > Main Window > Window Controller > Document
