Get properties of NSManagedObject as NSDictionary

Question

If I have an NSManagedObject I've fetched from a context, how can I create an NSDictionary out of its dynamic properties without just copying each field into the dictionary explicitly?

If my managed object looks like this, for example:

@implementation Track

@dynamic artist;
@dynamic group;
@dynamic purchase_url;
@dynamic title;
@dynamic file_name;
@dynamic year;

@end

After fetching from the database, in this case, I need an NSDictionary with the same properties set to each of those @dynamic properties.

There is a faster way to convert an NSManagedObject to an NSDictionary (from Matthias Bauch response at https://stackoverflow.com/a/5664745/2294824) :

NSArray *keys = [[[myObject entity] attributesByName] allKeys];
NSDictionary *dict = [myObject dictionaryWithValuesForKeys:keys];
