Core Data iOS Essentials

By: Bintu Harwani, B. M. Harwani

Overview of this book

Core Data is the essential ingredient in data driven iOS apps. It's used for storing, retrieving, and manipulating application data in databases, XML, and binary formats. It's an essential component for iPhone, iPod Touch, and iPad apps.Core Data Essentials provides a clear, readable guide to the most useful aspects of Core Data. Built around a realistic example app, the book showcases the most important aspects of Core Data development in the context of a complete, functioning app written in Objective C.The book starts with a tour of how the app works. Then you'll see how to easily display data using the Table View. You'll learn how to develop an appropriate data model that fits the needs of your app, then implement that model as updatable data objects. You'll see how to update data and build relationships between objects and learn how Core Data can work with search, and how to provide your users with friendly data editing features.

Module to connect the MasterProduct's menu to the rest of the project

In this module, we will learn how to invoke the MasterProduct's menu from the View of the RootViewController class (the first View that appears on launching the application). We will see how a Toolbar control is placed on the View and how it invokes an action method that subsequently displays the View of the MasterProduct's menu.

The following are the steps involved in developing this module:

  1. 1. Defining the outlets and action methods in the header file: RootViewController.h.

  2. 2. Adding a Toolbar and Bar Button Item in the RootViewController class.

  3. 3. Coding in the implementation file: RootViewController.m to invoke the View of the MasterProductinfoController class.

  4. 4. Making the Toolbar to appear at the bottom of the View.

For controlling the controls that we will be placing in the View through the code, we need to define the outlets and action methods for them. So, let's start with that.
