Using Application Preferences
WHAT YOU WILL LEARN IN THIS CHAPTER
- How to add application preferences to your application
- How to programmatically access the Settings values
- How to reset your application's preferences settings
If you are a relatively seasoned Mac OS X user, you're familiar with the concept of application preferences. Almost every Mac OS X application has application-specific settings that are used to configure the application's appearance and behavior. These settings are known as the application preferences.
In iOS, applications also have application preferences. In contrast to Mac OS X applications, however, whose application preferences are an integral part of the application, iPhone preferences are centrally managed by an application called Settings (see Figure 9-1).
FIGURE 9-1
The Settings application displays the preferences of system applications as well as third-party applications. Tapping any setting displays the details, where you can configure the preferences of an application.
In this chapter, you learn how to incorporate application preferences into your application and modify them programmatically during runtime.
