Let's say you have a killer app idea for iPhone and iPad. Where do you begin? Head First iPhone and iPad Development will help you get your first application up and running in no time. You'll not only learn how to design for Apple's devices, you'll also master the iPhone SDK tools -- including Interface Builder, Xcode, and Objective-C programming principles -- to make your app stand out. Whether you're a seasoned Mac developer who wants to jump into the App store, or someone with strong object-oriented programming skills but no Mac experience, this book is a complete learning experience for creating eye-catching, top-selling iPhone and iPad applications.
* Install the iPhone OS SDK and get started using Interface Builder and XCode * Put Objective-C core concepts to work, including message passing, protocols, properties, and memory management * Take advantage of iPhone OS patterns such as datasources and delegates * Preview your applications in the Simulator * Build more complicated interactions that utilize multiple views, data entry/editing, and rotation * Work with the iPhone's camera, GPS, and accelerometer * Optimize, test, and distribute your application We think your time is too valuable to waste struggling with new concepts. Using the latest research in cognitive science and learning theory to craft a multi-sensory learning experience, Head First iPhone and iPad Development has a visually rich format designed for the way your brain works, not a text-heavy approach that puts you to sleep.

This practical book offers programmers the knowledge and code they need to create cutting-edge mobile applications, using Apple's iPhone SDK. The iPhone is one of the hottest new pieces of technology: a fully functional portable Unix operating system with the most advanced handheld user interface in existence. "iPhone SDK Application Development" covers development environment for both the iPhone and iPod Touch, from windows and navigation bars to more advanced layers of the iPhone SDK, such as screen transitions, low-level graphics rendering using CoreSurface, the MultiTouch API, and digital sound and music rendering with Celestial and CoreAudio. With this book, you will: understand how the iPhone works internally, with a complete introduction to the technology; learn how different iPhone components interact with each other; use your existing Mac OS X development skills by understanding the similarities between iPhone and Mac OS X Leopard; also learn about the iPhone-specific APIs, such as the user interface, to develop custom iPhone applications; and, get code examples to help you write various features of your application.
With "iPhone SDK Application Development", you'll learn how to create effective iPhone applications and games with the same tools Apple uses.

Even the best developers have seen well-intentioned software projects fail - often because the customer kept changing requirements, and end users didn't know how to use the software you developed. Instead of surrendering to these common problems, let "Head First Software Development" guide you through the best practices of software development. Before you know it, those failed projects will be a thing of the past. With its unique visually rich format, this book pulls together the hard lessons learned by expert software developers over the years. You'll gain essential information about each step of the software development lifecycle - requirements, design, coding, testing, implementing, and maintenance - and understand why and how different development processes work. This book is for you if you are: tired of your customers assuming you're psychic. You'll learn not only how to get good requirements, but how to make sure you're always building the software that customers want (even when they're not sure themselves); wondering when the other 15 programmers you need to get your project done on time are going to show up.
You'll learn how some very simple scheduling and prioritizing will revolutionize your success rate in developing software; confused about being rational, agile, or a tester. You'll learn not only about the various development methodologies out there, but how to choose a solution that's right for your project; and, confused because the way you ran your last project worked so well, but failed miserably this time around. You'll learn how to tackle each project individually, combine lessons you've learned on previous projects with cutting-edge development techniques, and end up with great software on every project. "Head First Software Development" is here to help you learn in a way that your brain likes...and you'll have a blast along the way. Why pick up hundreds of boring books on the philosophy of this approach or the formal techniques required for that one? Stick with "Head First Software Development", and your projects will succeed like never before. Go on, get started...you'll learn and have fun. We promise.
