In September 2013, Apple unveiled the latest iPhone with a range of hardware improvements. The most innovative feature of iPhone 5s was a thin metal band surrounding the home button, a fingerprint sensor called Touch ID. Developers clambered to know about the API. A year on and iOS 8 introduces a new framework giving developers the ability to use the fingerprint sensor.
The Local Authentication framework provides methods to prompt a user
to authenticate. You could use this as a login for your app or use it
just to protect sensitive data within an app. In this tutorial, I will
explain the options available to you, what data you can get from the
device, and we’ll also build a sample app.
This tutorial requires
Xcode 6 to create the project and you’ll need a device with Touch ID to
test the sample app that we'll create.
