This app is meant to be an example of the core concepts needed to develop iOS apps. It is a simple two screen app that presents your favorite quote on screen and allows you to edit it. The quote is also saved to disk using iOS keyed archiving.
Although simple, the app covers the following concepts of iOS development:
- the MVC pattern and model controllers
- view controllers and their lifecycle
- the view hierarchy
- storyboards
- basics of Auto Layout
- outlets and the target-action pattern
- view controller containers
- communication between view controllers and delegation
