Custom Types

JSONModelKit's support for mapping complete types allows for creating object types as other objects generated. Let's assume in the example below that the business listing result returns a sub-dictionary for a location, and we would like to store it as a Location type.

Response Dictionary

{
	'business_uuid'    :  9223123456754775807,
	'business_name'    : 'NY Restaurant',
	'business_rating'  :  5,
	'business_location : {
	     'longitude' : 40.7053319,
             'latitude'  : -74.0129945
	},					
	'business_open'    : 1
}

Mapping

/Model/Mapping/Location.json | PLIST Equivalent

First, create a model mapping for the Location object.

{
    "longitude" : {
	 "key"  : "longitude",
         "type" : "Double"
    },
    "latitude"  : {
         "key"  : "latitude",
         "type" : "Double"
    }
}

Once the model mapping for a location has generated a Location object, and it has been added to the project, update the Business object mapping by defining a location property typed as Location

/Model/Mapping/Business.json | PLIST Equivalent

{
    "uuid" : { ... },
    "businessName" : { ... },
    "ratings" : { ... },
    "metaTags" : { ... },
    "open" : { ... }
    "location" : {
        "key" : "business_location",
        "type" : "Location"
    },
}

When parsing the data for a Business object, JSONModelKit will create a Location instance, and will assign the resulting value to the location property of the Business instance before returning it :)
