提问by Tirth
i m practising C++. i just add c++ files in XCode and write some string splitting functionality in it. After that i include that C++ file i.e. extension of .mm file in my AppDelegate file and call function from .h file of C++ class. But i found one static error in red line which is 'iostream' file not found. I used latest XCode version 4.5 and iOS 6.0. Please see screen shot of my error or xcode screen.
我在练习 C++。我只是在 XCode 中添加 C++ 文件并在其中编写一些字符串拆分功能。之后，我在我的 AppDelegate 文件中包含该 C++ 文件，即 .mm 文件的扩展名，并从 C++ 类的 .h 文件中调用函数。但是我在红线中发现了一个静态错误，即未找到“iostream”文件。我使用了最新的 XCode 4.5 版和 iOS 6.0。请查看我的错误或 xcode 屏幕的屏幕截图。

Objective Chaving .mextensions for its implementation files. If you want to use C++in Objective Cit should have .mmextensions. you can include C++header files in your .mmfile. But if you want to include your C++header files in your .hfile, you need to check macrofor that, like
Objective C具有.m其实现文件的扩展名。如果你想使用C++在Objective C它应该有.mm扩展。您可以C++在文件中包含头.mm文件。但是如果你想C++在你的.h文件中包含你的头文件，你需要检查macro一下，比如
#ifdef __cplus
#include <iostream>
#endif
But, I haven't tried any functions by including C++header file in .hfile. Hope it helps.
但是，我还没有通过C++在.h文件中包含头文件来尝试任何功能。希望能帮助到你。
