I've read a book called Objective-C for Dummies and I've watched all the videos on lynda.com for the following Objetive-C essential training, IOS 3.0 essential training, IOS5 New Features training, Xcode 4.0 New Features. I'm also half way through Paul Hagarty's lectures in Stanford on iTunesU for app development in IOS 5. I'm halfway through 1 week of annual leave from my day job, and I've spent at least 12 hours a day so far, over the past 4 days, studying further. You might have noticed a lot of posts from me on the iPhone programming forum, asking ridiculous questions. But because of you guys, you have kept me on track. Can I pull this off? Can I make an app in under a month, with no prior training? Has anyone?
