Overview of this book

If you are a developer looking to create mobile applications with maximized code reusability and minimized cost, React Native is what you need. With this practical guide, you’ll be able to build attractive UIs, tackle common problems in mobile development, and achieve improved performance in mobile environments. This book starts by covering the common techniques for React Native customization and helps you set up your development platforms. Over the course of the book, you’ll work through a wide variety of recipes that help you create, style, and animate your apps with built-in React Native and custom third-party components. You’ll also develop real-world browser-based authentication, build a fully functional audio player, and integrate Google Maps in your apps. This book will help you explore different strategies for working with data, including leveraging the popular Redux library and optimizing your app’s dataflow.

Background processing on iOS

Over the last several years, processing power in mobile devices has increased considerably. Users are demanding richer experiences and one method of achieving improved performance on modern mobile devices is via multithreading. Most mobile devices today are powered by multicore processors, and their operating systems now offer developers easy abstractions for executing code in the background, without interfering with the performance of the app's UI.

This recipe will cover both the use of iOS's Grand Central Dispatch (GCD) to execute asynchronous background processing on a new thread, and communicating back to the React Native layer when the processing is complete.
