Mutable dictionaries in NSUserDefaults?

Subject: Mutable dictionaries in NSUserDefaults?
From: Jonathan del Strother <email@hidden>

I've added an NSMutableDictionary called "FileDates" into my NSUserDefaults. I was hoping to access it with something like this :

[[NSUserDefaults standardUserDefaults] setValue:fileDate forKeyPath:@"FileDates.SomeFile"]

...but this raises an exception - "-[NSCFDictionary setObject:forKey:]: mutating method sent to immutable object"

Is the mutable dictionary converted to immutable on entering it into the user defaults? Does this mean that whenever I update a file date property, I have to extract the immutable dictionary, make a mutable copy, add the new file date, and re-enter it into user defaults, or is there a better way?

Jon
