Note that all classes in Objective-C should be capitalized. Listing 3-1. Declaring the Car Interface (Car.h) #import <Foundation/Foundation.h> @interface Car : NSObject { int year; NSString *make; NSString *model; } - (void) setMake:(NSString *) aMake andModel:(NSString *) a...
Classes, Objects, and Methods 下面学习的Object-c中的类,对象以及方法。 Objective-c作为一个面向对象的语言,其中最基础的就是Object.Object之名,就是对象,也就是一样东西。 就现实生活为例,我们的车子是一个对象,它有自己的属性(颜色、牌子等),自己的方法(启动,转左右等)。 言归正传,在OC中,假如我们定义...
Classes and Objects One of the major advantages of using object-oriented programming is that programming can create modules that are reusable modules that need to be changed when a new type of object is added. While having basic knowledge of the java programming language you can learn to write...
The CbaseObject class is the root of all base classes. It exists primarily to provide debugging assistance by keeping a count of all DirectShow objects that are active. All derived base class constructors provide a debugging object name as the first parameter and call the CBaseObject constructor...
The second-level macros,DECLARE_SERIALandIMPLEMENT_SERIAL, include all the functionality of the first-level macros, and they enable an object to be "serialized" to and from an "archive." For information about deriving Microsoft Foundation classes and C++ classes in general and usingCObject, see...

找出方法的最终执行代码:当程序执行[object doSomething]时,会向消息接收者(object)发送一条消息(doSomething),runtime会根据消息接收者是否能响应该消息而做出不同的反应。这将在后面详细介绍。 Objective-C runtime目前有两个版本:Modern runtime和Legacy runtime。Modern Runtime 覆盖了64位的Mac OS X Apps,还有...
Most of the classes in the Microsoft Foundation Class library are derived from the root class,CObject. These classes can be divided into the following categories: Application Architecture ClassesInternet Services Classes Array ClassesList Classes ...
