NSKeyedArchiver -> NSDictionary?

Hi,

Is there an elegant way to convert the data encoded by an NSKeyedArchiver into a corresponding NSDictionary suitable for use with NSUserDefaults? I was hoping to be able to use an NSKeyedArchiver in building the default preferences for an app. The methods provided in Foundation seem tantalizingly close to providing what I want. The following code goes part of the way towards what seems to me an inelegant solution (basically "manually" decomposing the property list).

NSMutableData* data = [NSMutableData data];
NSKeyedArchiver* archiver = [[[NSKeyedArchiver alloc] initForWritingWithMutableData:data] autorelease];
NSString* xmlString = nil;
id propertyListDictionary;

[archiver setOutputFormat:NSPropertyListXMLFormat_v1_0];
//archive some stuff ...
[archiver finishEncoding];
xmlString = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];
propertyListDictionary = [xmlString propertyList];
//...

Is there a nice way to go from an NSKeyedArchiver to an NSDictionary in a form suitable for use with NSUserDefaults?

Please CC replies to me as well as sending them to the list. (I have a backlog of around 6400 cocoa-dev messages to sort through currently :-)).

Thanks.
