Right, I tried something like this earlier, but when I use
- (NSString*) localizedName {
return NSLocalizedString (self.name, nil);
}
I get an exception:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:
'keypath localizedName not found in entity <NSSQLEntity TestEntity id=1>'...
But then you would say I have to perhaps back it up by a real property?
