How to specify child objects type in an NSArray with Mantle


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];


+[NSValueTransformer mtl_externalRepresentationArrayTransformerWithModelClass:] is deprecated. The new API is +[NSValueTransformer mtl_JSONArrayTransformerWithModelClass:].

After switching to the new API, the models can be initialized with the default initializers provided by, e.g., MTLJSONAdapter.


A note on:

[NSValueTransformer mtl_JSONArrayTransformerWithModelClass:CarModel.class];

This methods seems to now be deprecated. I'm using this new method in my code and it appears to be working just fine:

[MTLJSONAdapter arrayTransformerWithModelClass:CarModel.class];
