The iPhone developer's cookbook

I bought this book when the company I was working at in Tokyo in 2010 decided they wanted me to write IOS Apps for their company, I had Zero experience with iOS / or Obj-C. (I had come from 10++ years of C/C++ & Java on Linux)This book is still relevant today (2016), although I did find some errors.

First of all, this book is not a tutorial or a textbook. It is not designed to teach users how to program on the iPhone.

This book is not for someone who wants to learn iPhone development from scratch. Erica Sadun's iPhone dev cookbook is the best among all Iphone development books written!!
