I encounter a Core Data problem when blend adding new managed object and modifying other existing managed object before I call save.
Data will appear 2 times in the UITableView backed by a NSFetchedResultsController object.
I have detail explanation of the problem here: http://www.headnix.com/blog/126/new-managed-object-appear-twice-in-uitableview-backed-by-nsfetchedresultscontroller
Do you think it’s a bug? Or just behavior of Core Data + NSFetchedResultsController that we have to be aware of?
Appreciate your time and effort reading my post.
