MVC简单的说就是Model View Controller(模型，视图，控制器)，其用意就是将数据与视图分离开来，充分理解iOS的MVC模式，有助于我们程序的组织和理性。
MVC的明显特征和体现：
1.View视图的显示，取决于Model，只要Model数据改变了，View的显示状态也会跟着改变
2.Controller负责初始化Model，并将Model传递给View去解析展示
3.简单的MVC即控制器加载模型数据并数据转化为数据模型，控制器创建视图控件，并将模型数据传递给视图控件。
4.MVC的缺点：较差的可测试性，由于控制器混合了视图处理逻辑和业务逻辑，分离这些成分的单元测试成了一个艰巨的任务，大多数人选择忽略这个任务，那就是不做任何测试。
5.MVC的优点：低耦合性、高重用性和可适用性、可维护性（分离视图层和业务逻辑层也使得应用更易于维护和修改）。
