The upshot of all this is that the menu item s target object, whether configured explicitly or found in the responder chain, is the one that decides whether the menu item should be enabled (at the current time) or not. This means that you have complete dynamic control over each menu item. By implementing validateUserInterfaceItem: in each of your classes containing methods that are called by menu items, whether directly or through the responder chain, you can define some logic that the menu system calls at the right time, and automatically enables or disables each menu item based on what you return. Let s illustrate this with an example. We ll create a new window in our nib file, matched by a new delegate class just for that window, which will implement validateUserInterfaceItem: to handle the state of a menu item. In a real application, you would probably base it on the content of a model object, but for simplicity s sake, we ll enable or disable a menu item based on what s selected in the window. Start by creating a new class in Xcode, just a plain NSObject subclass called ListWindowDelegate. In its header, define an integer property called selectedTag, which we ll later bind to a GUI object (add the lines that are shown in bold):

When you create an autorelease pool, it automatically becomes the active pool. When you release that pool, its retain count goes to 0, so it then gets deallocated. During the deallocation, it releases all the objects it has. When you re using the AppKit, Cocoa automatically creates and destroys an autorelease pool for you on a regular basis. It does so after the program handles the current event (such as a mouse click or key press). You re free to use as many autoreleased objects as you like, and the pool will clean them up for you automatically whenever the user does something.

When you created the project as a Core Data enabled project, Xcode s template magic should have created a file called OfflineMailer.xcdatamodel. Double-click it, and you should get something that looks like Figure 7-13.

This is a much more common way of handling the situation. Remember, all you care about is that the interior of the parentheses boils down to $True or $False in some fashion. In this case, because the Responding property already provides one of those two values, you don t need to do any more work. Here s a quick tip: I learned about the Responding property by running GetProcess | Gm. In the list, I saw Responding and wondered what kind of information it contained. Would it be a 0 or 1 A Yes or No Something else So I ran Get-Process | Format-List *, which displayed all of the processes properties and their values. That output showed me that Responding contained True for almost all of my processes, so I logically assumed that False was also a possibility. I encourage you to use this same technique to discover what s inside the properties of other objects you work with.

I ve mentioned most of these practices already, but this is a good time to quickly review them:

1. Technically, structs are derived from System.ValueType, but that s only an implementation detail. From a language perspective, they act as if they re derived from System.Object.
