iPhone SDK Essential Training presents the tools and skills needed to create applications for this mobile platform. Developer Simon Allardice breaks down the process of becoming an iPhone developer, from getting started with the tools and the language to building user interfaces and working with the unique features of the iPhone. With multiple hands-on exercises and demonstration projects, Simon explores the core development tools for iPhone (Xcode, Interface Builder, and Instruments), the language (Objective-C), and the framework (Cocoa Touch). Exercise files accompany this course.
Topics include:
- Creating projects in Objective-C
- Understanding memory management and delegation
- Building user interfaces in Interface Builder
- Saving data and preferences for iPhone applications

Frequently asked questions
Find answers to the most frequently asked questions about iPhone SDK Essential Training (2009).
- Q: I am using Xcode 3.2.1, but cannot find the Foundation tool or the Command line in Utilities. How can I locate these tools?
- A: In later versions of Xcode that were released after the title was recorded, Apple changed a few things around in their "New Project" window, but it's just cosmetic. The Command Line / Foundation tool project is still there, you just get to it a slightly different way.
When you create a new Project:
1. Select the "Application" section under Mac OS X (*not* the one under iPhone, because we're not creating an iPhone app yet)
2. On the top pane on the right, select "Command Line Tool"
3. On the drop-down list, select Foundation.
- Q: Will most of the content in this title relevant for the iPhone SDK with the new version 4.0?
- A: Yes, the iPhone SDK Essential Training course is still relevant for the iPhone SDK 4. Of course, there are a few topics that have been superseded, but we'll soon be releasing an add-on course, designed to follow the iPhone SDK Essential Training course, that covers developing apps that use the new features in iOS 4.
Also, check out the following resources:If you're having issues getting the example projects to work, check "Updating SDK 3.0 Exercise files to use SDK 4"If you're having problems with creating the first simple projects (the command line examples), check out "Creating a Command Line Project." - Q: I don't have any experience writing code. What course should I take as a prerequisite to iPhone SDK Essential Training?
- A: Yes, the iPhone SDK course isn't that friendly if you have no coding background. But the following courses are a good starting point.
- JavaScript Essential Training (2011) - This course is quite a bit friendlier for new programmers, and talks about all the core programming concepts (like variables, loops, and conditions).
- Objective-C Essential Training - If you feel like jumping in at the deep end, try starting with this course. That's the language you'd need for iPhone SDK app creation. While I also wrote that course expecting some basic programming knowledge, I've heard from several folks who worked their way through it without it. Typically you'd just expect to repeat some content two or three times before you really "get it".
And as we speak, I'm creating a "Programming Fundamentals" course for lynda.com. Check for that course when it's released. It should give you a solid foundation in the basics.
