So I need to use vectors in my project. I have changed the .m file to .mm to make it Objective-C++. But, when I try saying:
所以我需要在项目中使用向量。我已经将.m文件更改为.mm以使其成为objective - c++。但是，当我试着说:
#include <vector>
In my .h it says the file or directory can not be found. If I put that line of code though in my .mm file though the error doesn't appear, but since I need a vector in the @interface (which is in my .h) what should I do to make the .h file find the vector file?
在my .h中，它表示无法找到文件或目录。如果我把这行代码放到。mm文件中，虽然错误不会出现，但是因为我需要一个@interface中的向量(在我的。h中)我应该怎么做才能使.h文件找到向量文件?
Also, I have tried changing it to compiling everything as Objective-C++, but that doesn't work because I get some errors in the Cocos2d library I am using...
另外，我试着将它转换为objective - c++，但这不起作用，因为我在Cocos2d库中有一些错误。

Is your .h file being included in any OTHER .h or .m files?
您的.h文件是否包含在其他的.h或.m文件中?
If so, you'll have to make those (or files including them, etc) into .mm as well.
如果是这样的话，你就得把那些(或文件包括它们等)变成。mm。

Without changing any .m to .mm or anything like that, if you click your project, click tagets->build settings go all the way down to "LLVM GCC 4.2 - Languages" you will see Compile Sources As change that value to Objective-C++;
如果你点击你的项目，点击tagets->构建设置一直到“LLVM GCC 4.2 -语言”，你将会看到编译源会把这个值变成Objective-C++;
