About the Cover

Striped dolphins live to about 55-60 years of age, can travel in pods numbering in the

thousands and can dive to depths of 700 m to feed on ﬁsh, cephalopods and

crustaceans. Baby dolphins don't sleep for a full a month after they’re born. That puts

two or three sleepless nights spent debugging code into perspective, doesn't it?

Section 1: Getting Started

This section introduces you to the ﬁrst of the four apps you'll build over the course of

this book — Bull's Eye.

As you progress through building the Bull's Eye app, the section will teach you how to

think like a programmer and how to plan your programming tasks. In addition, you'll

also learn how to use Xcode, Interface Builder and even the basics of coding for iOS.

While some of the concepts in this section might seem a bit basic, please do not skip

this section if you are new to iOS development — you will learn some fundamentals

which act as the building blocks for what you learn later.

This section contains the following chapters:

Chapter 1: Introduction

Chapter 2: The One-Button App

Chapter 3: Slider and Labels

Chapter 4: Outlets

Chapter 5: Rounds and Score

Chapter 6: Polish

Chapter 7: The New Look

Chapter 8: The Final App

有一个师傅进程和三个学徒进程，每个学徒连续不断地组装产品，做一个产品需要A. B、C三种零件，这三个学徒分别掌握有A零件、B零件、C零件多个。要求完成以下功能: （1）师傅源源不断地供应上述三种零件，但他每次只将其中的两种零件放在桌子上（所放零件由rand%3函数生成的0-2之间的随机数决定)。 (2）具有另一零件的学徒就可以组装产品，且做完后给师傅发信号，然后师傅再拿出两种零件放在桌上。 3）每次只能有一个进程放入或取出零件。（4）利用同步与互斥的相关知识编写仿真系统实现以上过程，要能够清晰表达产品生产的全过程。
