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 :)
