Overview

If you've been paying any attention at all to iOS 4 on the iPhone, you know multitasking is a big deal. But multitasking in an iPhone world isn't anything like multithreading or traditional multitasking. In this O'Reilly Breakdown, experienced iOS 4 programmer Mike Morrison explains what multitasking is, and teaches you how to get your own apps multitasking. You'll also build backward compatibility to support the still-huge number of devices that don't support multitasking.

The experts in the O'Reilly Breakdown live video series not only break down the concepts of difficult and complex subjects, they also demonstrate practical implementation and use. Each episode features an experienced programmer, developer, or software designer working on real-world challenges, ranging from iPad user interface design and multi-tasking on Android phones to caching in cloud-based applications.
