React Native Blueprints

Overview of this book

Considering the success of the React framework, Facebook recently introduced a new mobile development framework called React Native. With React Native's game-changing approach to hybrid mobile development, you can build native mobile applications that are much more powerful, interactive, and faster by using JavaScript This project-based guide takes you through eight projects to help you gain a sound understanding of the framework and helps you build mobile apps with native user experience. Starting with a simple standalone groceries list app, you will progressively move on to building advanced apps by adding connectivity with external APIs, using native features, such as the camera or microphone, in the mobile device, integrating with state management libraries such as Redux or MobX, or leveraging React Native’s performance by building a full-featured game. This book covers the entire feature set of React Native, starting from the simplest (layout or navigation libraries) to the most advanced (integration with native code) features. By the end of this book, you’ll be able to build professional Android and iOS applications using React Native.

Preface

Adding an icon


Once we have our icon designed and saved as a large image, we need to resize it to all the formats Apple requires. In general, these are the sizes required:

  • 20 x 20 px (iPhone Notification 2x)
  • 60 x 60 px (iPhone Notification 3x)
  • 58 x 58 px (iPhone Spotlight - iOS 5,6 2x)
  • 67 x 67 px (iPhone Spotlight - iOS 5,6 3x)
  • 80 x 80 px (iPhone Spotlight - iOS 7-10 2x)
  • 120 x 120 px (iPhone Spotlight - iOS 7-10 3x && iPhone App ios 7-10 2x) 
  • 180 x 180 px (iPhone App ios 7-10 3x)

Since this is a very tedious process, we can use one of the online tools which automate all the resizing tasks by providing an image large enough. One of the most popular tools can be found at https://resizeappicon.com/.

Once we have our icon in the proper sizes, we need to add them to our XCode project. We will do this by clicking on Images.xcassets in XCode and adding each image with its corresponding size to each asset in this window:

The next time we compile our app, we will see our new icon in the simulator ...
