I want to put an NSMutableDictionary into my standardUserDefaults with keys and boolean values [NSNumber numberWithBool:YES/NO], then bind that to a table with keys and checkboxes in my preferences window. That all seems to work nicely, except that when I check one of the checkboxes I find that NSNumber needs a setBoolValue method to be KVC compliant.

So I need an object that is both property list compliant and KVC compliant for a BOOL value.

Is there a standard workaround somewhere?

Are you binding to "foo.bar.boolValue"? You should just bind to foo.bar.


Since an NSNumber is immutable, any request for a setBoolValue: method raises a red flag -- why is something trying to modify an NSNumber. That thing, whatever it is, should be trying to replace that NSNumber.

Cheers,
