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];
