Effect

Characteristics

* Support Rich Text

* Customizable Strong (inheriting parent class overriding the Startanimation method of the parent class)

* Support for animation interrupts and persistence

* Support camediatimingfunction

* Data is isolated from the UI so you could encapsulate your class

Description

The parent class Popnumbercount is designed to resemble a policy pattern in design mode, providing an interface for subclasses to override to implement a different function, and the parent class will not be modified to a subclass, only the specific implementation in the subclass needs to be modified. (A protocol in the parent class is similar to a policy, implemented by a subclass)
