As the fourth book in our series of iPhone Projects based on the work and experiences of iPhone, this volume takes on the more advanced aspects of iPhone development. The first generation of iPhone applications has hit the App Store, and now it's time to optimize performance, streamline the user interface, and make every successful iPhone app just that much more sophisticated. Paired with Apress's bestselling Beginning iPhone Development: Exploring the iPhone SDK, you'll have everything you need to create the next great iPhone app that everyone is talking about. Optimize performance. Streamline your user interface. Do things with your iPhone app that other developers haven't attempted.
