Chapter 19. Instant Information with a Today Extension

When a user swipes right on the Lock Screen or in the Notification Center, they are taken to section called the Today View. In this section, users are presented with several widgets that provide useful information at a glance. These widgets are called Today Extensions.

In this chapter, you will learn how you can build a Today Extension so you can integrate useful information from your app with the Today View. A proper integration with the Today View can help users see the information they care about at a glance. The basis for the extension that you will build in this chapter is an inspirational quote app called The Daily Quote. In its current state, The Daily Quote only shows a quote when the user opens the app. You will expand this app by implementing a Today Extension.

This chapter covers the following topics:

  • Understanding the anatomy of a Today Extension
  • Adding a Today Extension to your app
