You can use RestKit (a Cocoa RESTful web services framework) to fetch the data and use the object mapping feature to map returned data to an array of objects.

The example given in the RESTKit Object Mapping wiki maps a JSON doc into an array of Article instances: https://github.com/RestKit/RestKit/wiki/Object-mapping
