iOS design mode-Abstract factory

Schematic diagram

Description

1. Abstract factory refers to the provision of an interface that creates a series of related or interdependent objects without specifying their specific classes

2. If multiple classes have the same behavior, but the actual implementation is different, it may be necessary for an abstract type to be inherited as its parent class, which defines the common behavior that all related concrete classes will share.
