A document class that mimics UIManagedDocument to support Core Data in all its modern glory:
-
Saves to a file package
-
On 10.7+, asynchronous saving is supported. We set up a parent/child pair of contexts; the parent saves on its own thread
-
Full support for concurrent document opening too
-
Subclasses can hook in to manage additional content inside the package
-
A hook is also provided at the best time to set metadata for the store
-
New docs have the bundle bit set on them. It means that if the doc gets transferred to a Mac without your app installed, with the bundle bit still intact, it will still appear in the Finder as a file package rather than a folder
-
If the document moves on disk, Core Data is kept informed of the new location
-
If multiple validation errors occur during saving, the presented error is adjusted to make debugging a little easier
-
And of course, full support for Autosave-In-Place and Versions
Standard BSD licence.
