Book Description

Now that multicore processors are coming to mobile devices, wouldn't it be great to take advantage of all those cores without having to manage threads? This concise book shows you how to use 's Grand Central Dispatch (GCD) to simplify programming on multicore iOS devices and .

Managing your application’s resources on more than one core isn't easy, but it's vital. that use only one core in a multicore environment will slow to a crawl. If you know how to program with Cocoa or , this guide will get you started with GCD right away, with many examples to help you write high-performing multithreaded apps.

  • Use different methods for executing and non- tasks
