Option Selector

Summary

Create a simple app with a few different categories (dogs, cars, food, planets, etc). When you tap on a category name it should take you into another UITableViewController with a list of possible options. Tapping on an option will show a checkmark at the right of the cell, and remove any other checkmarks on any other cells. When you navigate back to the initial UITableViewController you should see the option that you chose next in the corresponding cell. That is all.

You may pick any categories that you want.

Organization

This is a suggestion for how to organize your data.

  1. Each category is represented by a class, let's call it CQCategory. This class has 3 properties: name (NSString*), options (NSArray*), selection (NSString*)
  2. In your root UITableViewController, add a property that is an NSArray that can hold all of your CQCategory objects.
  3. In prepareForSegue, pass the corresponding CQCategory object to the destination UITableViewController

Process

  1. Start simple. In your storyboard, drag out a UINavigationController with UITableViewController as the root view controller. Add an additional UITableViewController. Create a segue when the user taps on a cell in the first UITableViewController.
  2. Set up your data.
  3. Populate your first UITableViewController based on the data that you set up.
  4. Make sure that navigating between UITableViewControllers is working. You'll need to pass relevant information to the second UITableViewController in prepareForSegue:
  5. Set up the selection interaction in the second UITableViewController. You'll need to implement on of the UITableViewDelegate methods. The checkmark is cell.accessoryType, so it's built in.
  6. When selection is made on a cell, update the corrosponding objects selection property.
  7. Make sure that the cells in the first UITableViewController are displaying the selection property.
