Chapter 10. Building a Settings View

What we are going to be adding in now is a settings view where we will let users configure what features of the app they wish to make use of.

For the Selfiegram settings we’re going to use another table view controller, with each row containing a toggle switch letting our users turn on and off particular features. Initially it will only contain two rows, one for enabling location support and another for setting a reminder in the app to take a selfie each day. This is intentionally limited because at the moment our app is nice and simple; as we expand the app we can easily add in more settings if necessary. In this chapter we will be doing the main chunk of work required for the settings to work and enabling users to configure location support. In the next chapter we will add in support for optional reminders.

Our first step is to get the new UI for our settings up and running.
