Today, virtually every non-trivial iPhone and
iPad app must manage data—quickly, smoothly, reliably,
and with minimal impact on the CPU to conserve battery
life. Core Data, Apple’s ready-made data persistence
layer, can help you achieve all these goals. In Core
Data for iOS, two leading iOS developers teach you the
entire Core Data framework from the ground up. Writing
for intermediate-to-advanced iOS developers, Tim Isted
and Tom Harrington thoroughly explain how Core Data is
used on iOS devices, introduce each of its primary
classes, and show how they interact to provide amazing
functionality with minimal configuration. You’ll learn
how to store, fetch, and validate data; provide it
efficiently to views; and much more. Isted and
Harrington first give you a firm grounding in the
technology, and then present real-world examples. They
present multiple sample projects, as well as a
start-to-finish, chapter-length case study. Coverage
includes
• Understanding Core Data’s
features, classes, and interactions
• Using Core Data
in MVC-based iOS app development
• Mapping relational
data to object models, and building them with Xcode 4’s
Data Modeler
• Working with managed objects and using
UITableView to display them
• Creating predicates to
match numbers, data, and objects
• Maintaining
compatibility across versions of an app’s data
model
• Tracking managed object contexts across view
controllers
• Using Core Data’s automatic Undo
functionality
• Integrating abstract entities,
entity inheritance, and multiple view controllers into a
complete app
• Optimizing for iOS devices’ tight
memory limits
• Diagnosing and fixing common Core
Data problems
Introducing Addison-Wesley’s
new Core Frameworks Series, written for experienced iOS
developers by world-class Mac and iOS developers, these
are the first comprehensive, code-rich reference guides
to Apple’s Core Frameworks.
