How to specify child objects type in an NSArray with Mantle

Question

If I have a dictionary like

{
  name: \"Bob\",
  cars: [
    { make: \"ford\", year: \"1972\" },
    { make: \"mazda\", year: \"2000\" }
  ],
}

Answer 1

Ah figured it out. I needed to add a private method:

+ (NSValueTransformer *)carsTransformer
{
    return [NSValueTransformer mtl_externalRepresentationArrayTransformerWithModelClass:[CarModel class]];
}

and make sure I used:

[PersonModel modelWithExternalRepresentation:dict];
