Please share some knowledge:
What is usually put in a model?
Does View refer to the things drawn on the Storyboard and the UIView you add using the code addSubview?
Controller is responsible for explaining the model to View. What is usually put in it?
It would be best if you could give me a simple MVC example, I would be grateful
Model中放的是业务逻辑
View指的是视图,一切显示出来给用户的东西
Controller负责控制视图的更新,与Model交流的桥梁
建议看一下Stanford CS193P第一个计算器实例,就能对MVC有一个理解了
