Fetching Portions of Entities

My previous post led to some Twitter traffic, and it led Dad (he goes by Dad) to do some investigating.

The documentation for setPropertiesToFetch says one thing and the .h file says another. Contrary to the documentation — but per the .h file — you can use this with managed objects. From the .h file: “the results are managed object faults partially pre-populated with the named properties.”

This almost what I want.

What I’d like even more is to get objects back as faults, but have only those specified properties fetched when the objects are un-faulted.

Other properties would get fetched only when one of them is accessed. Which wouldn’t happen in the case of Vesper’s timeline, but would happen when a note’s detail view is displayed.
