It's pretty much the same as any other operation on with a MOC. You cannot copy or move a managed object from one MOC to another in a simple fashion. Instead, you have got to create new, corresponding objects in the second MOC, and then (if needed) delete the old objects from the first MOC.

Given the introductory clause ("It's pretty much the same as any other operation on with a MOC"), this is potentially misleading. This applies to the specific case where you want to move data from one store to another. For "typical operations with a context", you don't want to move records between stores. If you're using multiple contexts, the more likely scenario is that you have a realisation of a given record in one context and you want another realisation of the same record in another context. For that you do not *create* new objects in the second context (and you don't *delete* the old objects in the first context); instead you ask the context for a managed object using objectWithID: or similar. mmalc _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
