IOS_21 Group Purchase _ Controller inheritance diagram

Eventually:

Controller inheritance diagram:

Description

Click the button on the dock to the left of the main controller,

such as "group Purchase", "collection", "Map",

There are many similarities to the functionality implemented.

Specify the following:

Click "Group buy" to show a group of nine Gongge,

And, when you click on a cell, display the cell's corresponding group purchase details

Click "Collection" to display a nine Gongge in the form of an archived buy model,

And, when you click on a cell, display the cell's corresponding group purchase details

Click "Map" to display the group purchase model in the form of a pin on the Mapview (city name + longitude + latitude + radius for parameter sending request)

Also, click on a pin to display the cell's corresponding group purchase details

The main functions and methods of the above controllers are stated as follows:

The extracted parent class is as follows:

Parent class Showdealdetailcontroller

Responsible for creating and presenting and hiding the packaged "buy details Controller"
