Summary

In this chapter, we first saw the meaning of the code that is automatically generated for us by Core Data in the Application Delegate files. Then, we saw the step-by-step procedure of saving, listing, and deleting customer names. We have also learnt about the concept of KVC and its methods used in setting and retrieving attribute values from the managed object. We also saw the different methods of the NSFetchedResultsControllerDelegate protocol. In the next chapter, we will see how to implement the concept of multiple managed object contexts to our application and also how to merge the information in different managed object contexts. We will also learn how to apply the knowledge gained in this chapter to maintain a customer's information, that is, we will see step-by-step how to save, display, and delete the customer's information.
