Second midterm topics

The second midterm exam will focus on the following topics:

• Displaying lists in a table view
• Placing a UITableView in a view along with other user interface elements
• Setting up a navigation view and segues between views
• Passing objects from one view to another in a prepare() method.

Practice problem

Write a simple app that implements a menu and ordering for a restaurant. The main view of the app will display a list of menu items. Clicking on one of the items in the list shows a more detailed description of the item:

Clicking the Order button adds the selected item to the user's order.

Clicking the View Order item in the navigation bar triggers a segue to a second view that displays the user's current order.

Here is the code for a couple of the classes you will need:

struct MenuItem {
    let title : String
    let description: String

    init(title t : String,desc d : String) {
        title = t
        description = d
    }
}

class CafeModel {
    var items : [MenuItem]
    var order : [MenuItem]

    init() {
        items = []
        items.append(MenuItem(title:"Hamburger",desc: "Two all beef patties, pickles, and lettuce on a sesame seed bun"))
        items.append(MenuItem(title: "French Fries", desc: "Chunky fries made from the finest Idaho potatoes"))
        items.append(MenuItem(title: "Garden Salad", desc: "Lots of iceberg lettuce and ranch dressing"))
        items.append(MenuItem(title: "Apple Pie", desc: "Made with fresh locally grown apples"))
        items.append(MenuItem(title: "Tacos", desc: "We got these from Taco Bell next door"))
        order = []
    }
}

Here is my solution to the practice problem.
