解决方案

他们都是。

MVC是一个模糊的模式。

我对MVC的观点是：

控制器

Object具有模型集合，并具有查看和编辑模型的方法。它与模型进行交谈，并返回具有应用模型的视图实例。

查看

模型

p>

封装数据。有返回状态和更改状态的方法。

  //控制器
导入视图
 
类控制器
私人模型
 
 //查看
 import模型
 
类查看
 
 //模型
模型
  

模型不需要知道有关View / Controller的任何内容。视图需要知道模型的定义。控制器需要自己的模型，需要知道视图的定义。

您可以更紧密地联系他们，这是可选的。

解决方案

They all are.

MVC is a vague pattern.

My view on MVC is that :

Controller

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.

View

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

Model

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

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.

You can couple them more tightly, that is optional.
