The protocol defines a series of methods.The ID type hides the type of the class and can have several different implementation classes. Find out the actual type of objects only during the run timeThe implementation details in the API can be hidden

The classification mechanism is typically used to add functionality to existing classes that have no source code.Attention:The method in the classification is directly added to the class, which is like the intrinsic method in this class.Adding a
