Hi all,
The "Troubleshooting Core Data" document discusses the FAQ "SQLite store
does not work with sorting". It suggests: "you may need to subclass
NSArrayController so you can have it not pass the sort descriptors to
the database and instead do the sorting after your data has been fetched". [1]
I imagine this must have been done many times over by many people. Try
as I may, I cannot find any example code, or even a more detailed
discussion of what to override. I fear there may be edge cases
overriding such an important class, so want to be careful.
My ultimate goal is for all table and outline views in my app to sort
"correctly" (ie like the Finder[2]).
What is the correct way to achieve this?
