I restarted my activity learing iOS. I bought the book “Beginning iPhone 3 development” by Dave Mark and Jeff LaMarche. This is much easier to follow than the CS193 course. I might pick-up that course once I got some more experience. Current book is mainly geared towards learning the interface libraries for iOS (iPhone). And I miss the library changes for the iPad.
I follow the corresponding forum for the book and created a FAQ for each chapter. So I can more easily see what kind of changes and suggestions have been made.
I am now at Chapter 9, so I am progressing well. Every day I work for several hours. Still some pages to go.
I already notice however that I miss some Objective-C basics. So I might also get a more basic book, before I start on my won project.
