Beginning iOS 5 Application Development

SUMMARY

This chapter provided a brief introduction to developing your first iPhone application. You have created a simple iPhone application, designed its user interface using some of the built-in views, and then test it on the iPhone Simulator. You have also learned how to write a simple action for your Button so that it can display a message when the user clicks on it. Finally, you saw how to assign an image to be used as the icon for your application and how to set a launch image for your application.

Although you likely still have many questions, the aim of this chapter was to get you started. The next few chapters dive deeper into the details of iPhone programming, gradually revealing the secrets of how all those components that seem so mysterious at first work together to create your application.
