MVC模型视图控制器
Model
Manages the app data and state
Not concerned with UI or presentation
Often persists somewhere
Same model should be reusable, unchanged in different interfaces
View
Present the Model to the user in an appropriate interface
Allows user to manipulate data
Does not store any data (except to cache state)
Easily reusable & configurable to display different data
Controller
Intermediary between Model & View
Updates the view when the model changes
Updates the model when the user manipulates the view
Typically where the app logic lives.
