Using Cocoa bindings, I have a switch (NSButton) bound to an
NSUserDefaultsController. I have the switch's action set to a certain
method in my own controller object. This works fine: The switch's
state is remembered from invocation to invocation, and when I click
on the switch, my action method gets invoked.
But: on startup when the switch's state setting is reconstituted from
NSUserDefaultsController as NSOnState, the switch gets drawn with the
checkmark, but my action method doesn't get invoked as a result of
this. Is there a way to set it so my action method will get invoked
if the defaults setting of the switch is the ON state?
A switch's action method is invoked *any* time it is clicked, not
just when
the user switches it to the "on" state. So this really has nothing
to do
with the action method per se. You simply want to do something, on
startup,
if you discover that this default is YES. So do that (e.g. in
applicationDidFinishLaunching). m.

Run an if/else in the awakeFromNib method.
If that's the way it works, that's okay. I guess I was wondering if
Cocoa bindings could also initiate the action associated with the
switch when it sets it to the ON state, as though it were clicked, as
opposed to me checking for the state of the switch in code, and then
invoking the action method directly.
Thanks,
