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 a launch screen


The launch screen is an image iOS displays while your app is loading. There are several techniques to make this introduction pleasant for the user, like showing a preview of the user interface the user will see once the app is loaded. However, we will take a simpler approach: we will display the app logo with its title. 

The easiest and more flexible way to do this is to use the interface builder in XCode by clicking on LaunchScreen.xib

An interface builder is a WYSIWYG tool, which helps developers building responsive screens by dragging and dropping components into a container. We kept it simple and just added a label with the name of the app and the same logo we used on the app icon.

Another option could be to upload images as launch screens and remove the LaunchScreen.xib file, but then we would run the risk of stretching the images depending on which device the app is run, so the recommended approach is always to use the interface builder for launch screens.
