I have a related question about bindings and user defaults.
I use bindings for my prefs window that bind to NSUserDefaults
that are registered in my NSApplication (with registerDefaults: ).
For example, let's say that one of the values is a number that is
shown in an editable NSTextField.
My question is :
In IB, in the bindings pane, should I set a value for 'Null
Placeholder',
and should I enter a value in the control also ? Or should I completely
rely on the registered defaults ?
thanks.

Bind your master checkbox's 'value' attribute to your model (e.g.
user defaults) with whatever key path you want. Then, for each
of the checkboxes in your group, bind their 'enabled' attribute
to your model to the same key path as for your master checkbox.
Thanks for the tip. I noticed that there 2 kinds of userdefaults:
NSUserDefaultsController and the Shared User Defaults. Which one
should I use? I have seen in some examples that they use the
shared one, so what's the use of the other one?
Shared User Defaults is an instance of NSUserDefaultsController
that uses the standard user defaults for the application.
NSUserDefaultsController can be configured in a number of different
ways (for example, you can specify a different NSUserDefaults
instance to use).
So, use eh Shared User Defaults
