- A. Appendix
- Index
In this chapter, we saw how to apply the concept of multiple managed object context to our application. We have also seen how to merge the information in different managed object contexts. Finally, we have learnt the core of this chapter: how to maintain the customer's information, that is, we saw step-by-step how to save, display, and delete the information of the customer. In the next chapter, we will see how to update (modify) the information of the customer that is already stored with us. We will also be using KVO (Key Value Observing) to know what attribute of the object is updated. Besides this, we will also see the application of NSPredicate, a complex and powerful tool to apply a search facility to locate the desired customer name quickly.
