推荐答案

它们都是.

MVC是一种模糊的模式.

MVC is a vague pattern.

我对MVC的看法是:

控制器

对象具有模型的集合，并具有用于查看和编辑模型的方法.它与模型对话，并返回应用了模型的View实例.

Object has a collection of models and has methods for viewing and editing the models. It talks to Models and returns instances of Views with models applied on them.

查看

具有附加的模型定义，只是显示特定模型的一组功能.

Has the definition of a model attached to it and is just a set of functionality to display a specific model.

模型

封装数据.具有返回状态和更改状态的方法.

Encapsulates data. Has methods for returning state and changing state.

//Controller
import Views

class Controller
  private Models

//View
import Model

class View

//Model
class Model

模型不需要了解有关View/Controller的任何信息.视图需要知道模型的定义.控制器需要拥有拥有模型，并且需要了解视图的定义.

A Model doesn't need to know anything about the View / Controller. A View needs to know the definition of a Model. A controller needs to own Models and needs to know definitions of Views.

您可以更紧密地耦合它们，这是可选的.

You can couple them more tightly, that is optional.
