hi, i just need a book for to create apps for both iphone/ipad. i know objective-c language and i worked for a while on it. so i'm looking for a book that can teach step by step how to create apps or teach you in a way that it shows you how an app is being created besides the informations that it have (similar to what objective-c for dummies has which teach you objective-c along side with what's happening and the info's). i want a clear straight forward book not kind of a book that only give out informations, i want "practice first"!! Thank you!
