دانلود کتاب برنامه نویسی iOS

This book is based on the class we teach at Big Nerd Ranch. As such, it was designed to be consumed in a certain manner. Set yourself a reasonable goal, like, “I will do one chapter every day.” When you sit down to attack a chapter, find a quiet place where you will not be interrupted for at least an hour. Shut down your email, your Twitter client, and your chat program. This is not a time for multitasking; you will need to concentrate. Do the actual programming. You can read through a chapter first, if you like. But the real learning comes when you sit down and code as you go. You will not really understand the idea until you have written a program that uses it and, perhaps more importantly, debugged that program. A couple of the exercises require supporting files. For example, in the first chapter you will need an icon for your Quiz application, and we have one for you. You can download the resources and solutions to the exercises from www.bignerdranch.com/solutions/iOSProgramming7ed.zip. There are two types of learning. When you learn about the Peloponnesian War, you are simply adding details to a scaffolding of ideas that you already understand. This is what we will call “Easy Learning.” Yes, learning about the Peloponnesian War can take a long time, but you are seldom flummoxed by it. Learning iOS programming, on the other hand, is “Hard Learning,” and you may find yourself quite baffled at times, especially in the first few days. In writing this book, we have tried to create an experience that will ease you over the bumps in the learning curve. Here are two things you can do to make the journey easier: • Find someone who already knows how to write iOS applications and will answer your questions. In particular, getting your application onto a device the first time is usually very frustrating if you are doing it without the help of an experienced developer. • Get enough sleep. Sleepy people do not remember what they have learned.
