persistentStoreManagedObjectContext vs mainQueueManagedObjectContext

Question

Good evening!

So I've been having some trouble understanding what the hell is going on while saving my data in Core Data. First of all, a quick question:

1) When should I be using the persistentStoreManagedObjectContext and when should I be using the mainQueueManagedObjectContext?! Right now, I always use the persistentManagedObjectContext, but I can see that a RestKit call "getObjectsPath", the object will have the mainQueueObjectContext. Why is that?!

Thanks!

Answer 1

persistentStoreManagedObjectContext could be used to populate other another NSManagedObjectContext (e.g. for a background thread).

So unless your not leaving the main thread when accessing the object, use the mainQueueManagedObjectContext and you're on the safe site.
