Part IV

Finishing the Basic Application Structure

After you have the foundation in place, you need to make all those controls do something, such as when a user taps a button.

In this part, you start the actual coding process to turn a good idea (an app that you use when you take a road trip) into a real working app.

You start by adding animation and sound to the opening screen of your app so that when the user taps the Test Drive button, the ’59 Cadillac Eldorado Biarritz convertible takes off with a screech and then drives up and down the screen with a satisfying engine purr.

You also create the application model — the part of your application that manages the content. The content includes where the user is going, what to see when he or she gets there, and how to find out what the weather is like at that location.

You also add navigation to the application, including a screen that shows the features and functions available. In the process, you learn how to customize the appearance of the controls provided by the framework to make your application a thing of beauty.

And because your app will be using the Internet — a lot! — you also learn how to determine whether the Internet is available and how to alert the user when it is not.
