React Native By Example

By: Richard Kho

Overview of this book

React Native's ability to build performant mobile applications with JavaScript has resulted in its popularity amongst developers. Developers now have the luxury to create incredible mobile experiences that look and feel native to their platforms with the comfort of a well-known language and the popular React.js library. This book will show you how to build your own native mobile applications for the iOS and Android platforms while leveraging the finesse and simplicity of JavaScript and React. Throughout the book you will build three projects, each of increasing complexity. You will also link up with the third-party Facebook SDK, convert an app to support the Redux architecture, and learn the process involved in making your apps available for sale on the iOS App Store and Google Play. At the end of this book, you will have learned and implemented a wide breadth of core APIs and components found in the React Native framework that are necessary in creating great mobile experiences.

Reloading data with RefreshControl

The pull-to-refresh interaction was conceived with Tweetie, a popular Twitter iOS application created in 2008. This interaction involves the user pulling down their screen until it reaches a certain threshold, then releasing it to signify their intent to refresh the contents of the screen.

With the React Native SDK, we can use RefreshControl to gain that same pull-to-refresh interaction and let our users reload data in the app at their will.

Here are the RefreshControl props that we will use in this chapter:

  • onRefresh: This is a function that is called when the refresh action is executed
  • refreshing: This is a Boolean that indicates whether the view should be animated
  • tintColor: This is the color of the refreshing indicator
  • title: This is a string that is displayed underneath the refresh indicator
  • titleColor: This is the color of the title

To use a RefreshControl, render it into a ListView or ScrollView component under its refreshControl prop.

For our implementation...
