在本章中,我们将完全用C语言,实现面向对象中最重要的几个概念,分别是继承,覆盖。我们先看实现后的调用: int main (int argc, char ** argv) { void * p; while (* ++ argv) { switch (** argv) { case &#…
Objective-C 继承(Inheritance) 面向对象编程中最重要的概念之一是继承。继承允许我们根据另一个类定义一个类,它使得创建和维护应用程序更加容易,也提供了重用代码功能和快速实现的机会。创建类时,程序员可以指定新类继承现有类的成员,而不是编写全新的数据成员和成员函数。这个现有类称为 基类,新类称为 派生类。

继承:Inheritance in OOP means that a class acquires features from another class, its parent or superclass.(一个类(子类)的特性(属性+方法+协议...)来源于另一个类(父类)) 继承在Objective-C中的语法表示? 首先,通过上面的分析,圆、方形的特性可以由几何图形来提供,也就是说圆、方形是可以继承于几何...

将想法用代码直接表达使理解和维护更容易。确保用基类表现的想法准确地匹配所有的派生类型并且找不到使用继承这样的紧耦合之外更合适的方式。 Do not use inheritance when simply having a data member will do. Usually this means that the derived type needs to override a base virtual function or needs acces...
