I created a document-based core data application and want it to be
able to add external files from a support folder. I can
successfully set the permanent URIs for the transient relationships
working in memory, but for some reason saving to file never works
properly. If I tell each object to save the context using save: in
the didSave: method, it will save a duplicate in the file. If I try
to save the context in the document's document:didSave:contextInfo:
method mentioned in the documentation, it works again but doesn't
save. Thank you in advance for any information someone has on what
I'm doing wrong.
Did you get any responses to this and/or are you still having a problem?
If you're still looking for assistance, you're going to have to spell
things out a bit more clearly. Are the external files persistent
stores you add to the persistent store controller, or are they just
additional files you keep references to as property values? If you
have information in transient properties, why are you expecting those
values to be saved at all? What kind of context are you talking about?
If you mean managed object context, why are you telling objects to
"save" it? Etc.
