Digital Media Minute has done posts on how to build iPhone applications before, but Matt Gemmell has a superb quick-start ‘emergency guide’ for iPhone app development. (You know, when you have that incredibly unbelievable idea for an iPhone app and really bad things are going to happen if you can’t get started immediately…)
Much more than a cheat-sheet, it’s aimed at competent programmers who have neither the time or the need to be hand-held as they learn the essentials of iPhone development. This is a really good idea–a kind of hybrid resource that is cured just towards making quick progress, with the idea that the finer points can be worked out later.
