面向对象程序设计(英语:Object-oriented programming,缩写:OOP)是种具有对象概念的编程典范,同时也是一种程序开发的抽象方针。 它可能包含数据、属性、代码与方法。对象则指的是类(class)的实例。它将对象作为程序的基本单元,将程序和数据封装其中,以提高软件的重用性、灵活性和扩展性, 对象里的程序可以访问及经常修改...

Instead of just calling functions, you ask an object to do something. This takes the form of two elements within square brackets, the object receiving the message followed by the message itself: [object message] Here, the source code sends the message alloc to the Car class and then sends ...
