Gold Challenge: JSON Caching
Right now,
RSSChannel
and
RSSItem
instances are cached using the archiving data
format. Make it so they can also be cached as JSON. (Hint: add another method to
JSONSerializable
for storing an object's instance variables in a dictionary.) The
BNRFeedStore
should cache the Apple feed in JSON format and load it back from that
JSON format.
