Assignment 2

In this assignment, you'll make a more rounded iOS application.

We're going to hold your hand less on this one. How you approach the application is up to you.

Details

Your task is to create an app that:

Has a table view.
Uses an Add button to display a new screen.
On that screen, take input.
Add that to an array.
Save that array to a JSON file.
Populate the table view with this.
Load the data on app launch.

Notes

You'll want to use the NSJSONSerialization class to read and write the JSON data.
We suggest using two view controllers: one for the table view, and one for the "add" screen.
The table view controller and the add view controller will need a way to communicate, because the add view controller needs a way to tell the table view controller that new data is available.
The reloadData method on UITableView reloads all data in a tableview, refreshing the screen.
