In that case, try this: Create a category on NSManagedObject - @interface NSManagedObject (ObjectAsDictionary) - (NSDictionary *) objectAsDictionary; @end @implementation NSManagedObject (ObjectAsDictionary) - (NSDictionary *) objectAsDictionary { NSDictionary *dictionary = [NSMutableDictionary dictionary]; NSEntityDescription* entityDescription = [self entity] ; for (NSPropertyDescription *propertyDescription in entityDescription) { id propertyValue = [self valueForKey:[propertyDescription name]]; [dictionary setValue:propertyValue forKey:[propertyDescription name]]; } return dictionary; } @end Then simply call the following code on the original managed object when : { // assume an NSDictionary *editingWord property declared in your controller class editingValues = [editingWord objectAsDictionary]; // set object controller content to be editingValues ... } ... then after the edits have been made, use the following code to update the object to be stored: { //assume your object to be stored is called originalObject [originalObject setValuesForKeysWithDictionary:self.editingValues]; ... } > I hope it is a bit clearer, despite my rusty English. I speak French if that helps? :-) Joanna -- Joanna Carter Carter Consulting _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
