This lesson we try to develop a simple command-line games，To complete the experience a so-called "development process"。

This game is set：

This is a board game，We guess the location of enemy ships，As long as the number of hits you can send them to sink。

We give these ships the label affixed to point it ...... such a variety of sites?so，This has become a site of attack Behind his program ......。

Goal of the game

We want to attack the player with the least number of sites，It crushed。Then we scored based on the number of players guessing。

Roughly design

We draw a 7 * 7[……]

Before we in class，Take a look at the previously mentioned "SoC" concept，We say this is called "Separation of Concerns"，I translate it as separation of duties - the different sections that focus on their part。Or a target to achieve a goal。

The goal not only to make the code more modular and easier to maintain，Also let the system run more efficiently。So，We want the communication between objects becomes more standardized job。

Data Hiding

You go and see you writing framework code that, when used，Which gives you direct show[……]

Declare a variable

We use var to declare a variable，Congguizili like a tube placed in the experimental stage；

We give a specified variable type，Just like in the test tube labeled the；

Then put reagents must be marked on the label - otherwise could cause an explosion or poisoning。

Same，If we try to give a reservoir into a wrong data type，Then the compiler will complain - yes there is always a way to be able to fool the compiler - anyway, I will not teach you this method，That would cause it to crash。[……]

A lesson on our first taste OOP Style，Ambiguous classes and objects in exactly what is it? This lesson we use a simple little chestnut to introduce to you。

Trying to explain

We say that the relationship between classes and objects and the relationship between the design of products，Take Our house is，Certainly there will be a corresponding building design，But the design will not only correspond to a building，At least one cell must be met with a set of drawings is not it? Our "Class" is the "design"。We use this design designed object's properties、Function and so a series of content，Then instantiating yield[……]

Some students did not take into account the iPhone，Swift language learning but at least we will have OS X operating system，Our code shows will be completed in OS X，Using the CLI interface。So although it looks old and was，But believe me take the GUI make you worry a lot - because that is another matter。

So now，Let's say hello and OOP

We take a look，Developing with OOP in the end is what it looks like?

We are not taking into account the high level of development，So we put all the functions of real[……]
