Question

Still having trouble with this language.

Ok, let’s say I have two objects. The first is my application delegate, the second is a custom view containing the various buttons that make up the main menu. When a button is clicked, it is the menu that responds. However, I need to make use of certain instance variables in the application delegate (such as the Window) in order to implement the appropriate changes. In this case, I want the main menu to be removed and replaced with a new view. In other words, the main menu needs to trigger a method held in the application delegate.

So, how should I go about this?

Answer 1

I did a blog post on my web site a ways back that distills the process down into the simplest way I could come up with to describe setting up a delegate.
