I have a tree of managed objects with parent <--> child relationships, and Delete Rule set to Cascade children when a parent is deleted.

But sometimes, after deleting a parent, I need to restore a deleted child under a new parent. So I set the new relationships and also send

  [managedObjectContext insertObject:deletedObject] ;

It appears that -insertObject: "cancels" the object's previous Cascade-deletion. It definitely does not persist as desired if I don't to this.

Is what I'm doing OK?

I’d say no.

You can not re-insert a deleted object because it is unique in the database and as such dead and gone after deletion.

Either hang your object onto the new parent before deleting the old parent, or copy it’s data to a new object that you can then insert.
