Drew,
You could write a static method in you business class something like this:
I would do something like this:
public static Item itemWithMaxPrice(EOEditingContext ec) {
NSArray objects = EOUtilities.objectsForEntityNamed(ec, "Item");
NSArray sortedObjects = EOSortOrdering.sortedArrayUsingKeyOrderArray(objects, priceOrderings());
return (MyEO)sortedObjects.lastObject();
}
public static NSArray priceOrderings() {
EOSortOrdering priceOrdering = EOSortOrdering.sortOrderingWithKey("price", EOSortOrdering.CompareAscending);
return new NSArray(priceOrdering);
}

I have an NSArray with several objects in it. I want to select the object that has the maximum price. However, using valueForKey("@max.item.price") returns, of course, the price for the item instead of the item. Is there a way to do this without having to refetch?
