//1 Creating a New Managed Object Context
//To create a new managed object context, you need a persistent store coordinator.
NSPersistentStoreCoordinator *psc = <#Get the coordinator#>;
NSManagedObjectContext *newContext = [[NSManagedObjectContext alloc] init];
[newContext setPersistentStoreCoordinator:psc];
//using the same coordinator as the existing one
NSManagedObjectContext *context = <#Get the context#>;
NSPersistentStoreCoordinator *psc = [context persistentStoreCoordinator];
