Programming for the iPhone is still pretty new. It might be a bit tougher to find iPhone developer resources, but we found a bunch that will get you through building any iPhone app you might be starting on. Check out our list of our favorite developer books, blogs, podcasts, screencasts, open-source libraries, communities, forums, conferences, training, and more!

Books

Beginning iPhone Development: Exploring the iPhone SDK

This is the go-to book for beginning iPhone developers by Jeff Lamarche and Dave Mark. It takes you from downloading the SDK to creating your very own apps. The official page and support site: http://iphonedevbook.com/

Programming in Objective-C 2.0

This is the book to get if you’re just starting out programming. It assumes you have no prior programming knowledge before picking it up. It’s highly recommended for people who don’t know any programming and want to learn Objective-C. Not a lot of iPhone-specific stuff in this one, but a lot of this knowledge will carry over when you do want to create iPhone apps.

Cocoa Programming for Mac OS X

This book assumes you know a bit of C/C++, and it’s a really good book for getting started with Apple’s developer frameworks. There isn’t a lot of iPhone-specific stuff in this book, but a lot of what you learn carries over into iPhone development.

Pragmatic Programmers iPhone SDK Development

This book is in beta still, so you can only get the PDF. It was originally scheduled to be released by now, but they are updating it to include iPhone SDK 3.0. It’s still worth it to get the PDF. I’ve gone through it, and it is fantastic. The book is now set to be released in September.

The iPhone Developer’s Cookbook: Building Applications with the iPhone SDK

This book is full of code snippets that will help a lot of people with common tasks that Apple’s iPhone SDK doesn’t provide. There are some code blunders in this book, but luckily they’ve fixed the code and put it up here. They also have movies at this site that demonstrate what each mini-project does.

The iPhone in Action book covers both native and web programming in step-by-step tutorials. It’s a complete primer to iPhone development.
