Please help me: What is the key path of a value stored in the shared
user defaults?
I'm using a sub-classed NSViewController to enhance the print panel
with an accessory view:
NSBundle *appBundle = [NSBundle bundleForClass:[self class]];
NSViewController *accessoryViewController = [[PrintOptions alloc]
initWithNibName:@"PrintOptions" bundle:appBundle];
[[printOperation printPanel]
addAccessoryController:accessoryViewController];
The view "PrintOptions" includes three checkboxes, all bind to the
Shared User Defaults Controller. The printed view uses these values
to modify its output. Everything works fine except the preview in
the print panel: It isn't updated when I check / uncheck any of the
boxes, although the view controller conforms to the
"NSPrintPanelAccessorizing" protocol and should use KVO to be
notified for changes.
I think my "keyPathsForValuesAffectingPreview" implementation is
wrong as I don't know how to reference a shared user default:
- (NSSet *)keyPathsForValuesAffectingPreview
{
return [NSSet setWithObjects: @"PrintFastMode", @"PrintJumps",
@"PrintGrid", nil];
}
The documentation I found only mentioned an example with document
margins, but what is the key path for properties bind to the user
defaults? Sorry, I'm totally lost ...
OTOH, you could have an outlet to the defaults controller, say, named
"defaultsController" and use @"defaultsController.values.DEFALTSKEY"
to keyPathsForValuesAffectingPreview. I think that is supposed to
work...
