In this chapter, you will start building an application named CriminalIntent. CriminalIntent records the details of “office crimes” – things like leaving dirty dishes in the break room sink or walking away from an empty shared printer after documents have printed.

With CriminalIntent, you can make a record of a crime including a title, a date, and a photo. You can also identify a suspect from your contacts and lodge a complaint via email, Twitter, Facebook, or another app. After documenting and reporting a crime, you can proceed with your work free of resentment and ready to focus on the business at hand.

CriminalIntent is a complex app that will take 11 chapters to complete. It will have a list-detail interface: The main screen will display a list of recorded crimes, and users will be able to add new crimes or select an existing crime to view and edit its details (Figure 8.1).
