Agile Iphone Development
The document discusses iPhone app development using Objective-C. It covers the basics of getting started, including what is needed to begin like a Mac, Xcode, and an iPhone. It then explains key Objective-C concepts like classes, methods, and memory management using retain counts. The document also discusses unit testing iOS apps using OCUnit and some Xcode tips. It emphasizes testing first and concludes by noting the market demands more apps and there is room for improvement.
