Bring It on Home

Pat yourself on the back. Although it may not seem like you accomplished all that much in this chapter, we actually covered a lot of ground. You learned about the iOS project templates, created an application, learned a ton about Xcode 4, started using Interface Builder, and learned how to set your application icon and bundle identifier.

The Hello, World program, however, is a strictly one-way application. We show some information to the users, but we never get any input from them. When you're ready to see how to go about getting input from the user of an iOS device and taking actions based on that input, take a deep breath and turn the page.
