c ++，objective-c和objective-c ++之间有什么区别？ [英] What is the difference between c++, objective-c and objective-c++?

问题描述

我想知道c ++和objective-c和objective-c ++之间的区别。
任何一个可以给我的区别，我们可以使用c ++的iPhone开发

I want to know the difference between c++ and objective-c and objective-c++. Can any one give me the difference and Can we use the c++ for iPhone development

谢谢你，

推荐答案

C ++是Bjarne Stroustroup的基于向C添加类和元编程的语言，它将大多数额外的工作放入编译器，并且尽可能少

C++ is Bjarne Stroustroup's language based on adding classes and metaprogramming to C in such a way that puts most additional work into the compiler, and relies on least possible effort at runtime.

Objective-C是Brad Cox的语言，它基于向C添加一个SmallTalk风格的动态消息传递运行时库，并添加了少量的语法使得它更容易使用。

Objective-C is Brad Cox's language based on adding a SmallTalk-style dynamic message-passing runtime library to C, with a small amount of syntax addition to make it easier to use.

Objective-C ++，坦白地说，当你添加Objective-C运行时和语法到C ++时，你得到什么。它有它的局限性（例如，你不能创建一个C ++类的Objective-C子类，反之亦然，而Objective-C不喜欢C ++命名空间），但允许你使用Objective-C对象的C ++类，反之亦然。

Objective-C++ is, to put it bluntly, what you get when you add the Objective-C runtime and syntax to C++. It has its limitations (e.g. you can't create an Objective-C subclass of a C++ class or vice versa, and Objective-C doesn't like C++ namespaces) but allows you to use C++ classes from Objective-C objects and vice versa.

您可以在iPhone开发中使用Objective-C ++。这实际上意味着你可以编写一个应用程序的对象模型是完全C ++，控制器层需要接口到Objective-C，以使用Cocoa Touch API。

You can use Objective-C++ in iPhone development. What this means practically is that you could write an application whose object model was entirely C++, where the controller layer would need to interface to Objective-C in order to use the Cocoa Touch APIs.
