CoreData-JSON

CoreData-JSON is an extension to the Apple Core Data classes NSManagedObject and NSManagedObjectContext to import and export data of a managed object context from and to JSON data.

To get the JSON representation of a managed object simply call 'jsonObject'.

The JSON representation of a managed object looks like

{
    "entity" : "Employee",
    "id" : "AB9F1A3D-C12B-4A78-9BE6-059A9BA6C983",
    "attributes" : {
        "name" : "Bob",
        "since" : "2016-08-01T09:00:00-04:00"
    },
    "relations" : {
        "department" : "5B9F0B71-6CAF-4D15-B295-254F6C013050"
    }
}

The entire managed object context can be exported to json by calling jsonData. To import a JSON data into a managed object context use importJSONData

Examples

Swift

self.managedObjectContext.importJSONData(jsonData)

Objective-C

[self.managedObjectContext importJSONData:jsonData]
