I'm very interested in developing mobile apps and actually I'm an Android freelance programmer but I would like in the future to work also with Apple's devices, so this book promo it's really what I needed!
The Android books I have studied developed one or two apps from the first chapter to the last, have you choosen the same approach in your book?
And do you think having a knowledge of the Android programming could be useful in learning Objective-c?
having knowledge on a different mobile platform is very valuable: You already know about the hardware constraints of a mobile platform and the different UI/UX patterns on mobile devices. When it comes to the APIs, however, iOS is quite different from Android.
And yes: one application is developed throughout the book. Some chapters build some stand-alone applications as well, though.
