Anonymous users2024-02-07Object-orientation can be understood as the encapsulation of a process!
Traditional programming is process-oriented, object-oriented introduces the concept of classes and objects, and can encapsulate process-oriented methods in classes and then reference them by creating objects!
The most critical feature of object orientation is inheritance, especially for reuse, inheritance is very flexible, including overloading and other features.
Usually a class is done for a specific function, such as a database operation!
The traditional process-oriented database operation must be written on each background page with cumbersome SQL statements, now we have object-oriented technology, we can completely encapsulate the commonly used database operation methods in the form of a unified package in a class file called db, and then through inheritance, every page that needs database operations inherits the class, you can use the database methods in the class, such as the common "addition, deletion and modification"! In this way, each operation statement only needs to be written once in the DB, and there is no need to repeat it, which is one of the benefits!
That's a simple description of the object-oriented encapsulation process!

Apple's Swift will definitely replace OC in the future, but it didn't say how long, and then announced that OC is still a first-class citizen developed by Apple, and a lot of the information is described by OC.

Anonymous users2024-02-04You write a game project, and at a macro level, you are an object, and your project is also an object; To be a little more detailed, the character in the game is an object, and each object contains many properties, which are some characteristics of the object. The analogy is already obvious and understandable, right?
