包含< string>未找到编译错误在Xcode 4.2 [英] Include <string> not found compile error in Xcode 4.2

问题描述

我在XCode中包含未找到编译错误。我有一个iOS应用程序项目，我使用Objective-C和C ++作为混合。

I'm getting include not found compile error in XCode. I have an iOS app project that i use Objective-c and c++ as mix.

最初，我在ios项目中创建了一个.h文件和一个.cpp文件。然后，我将.cpp文件重命名为.mm文件。

Initially, i created one .h file and one .cpp file in my ios project. Then, I renamed the .cpp file to .mm file.

这是我的.h文件;

TestLog.h

TestLog.h

#ifndef CalculatorDemo_TestLog_h
#define CalculatorDemo_TestLog_h
#include <string>
using namespace std;

class TestLog
{
private:
    string logString;
public:
    void Log(string logMessage);
};


#endif

TestLog.mm

TestLog.mm

#include "TestLog.h"

void TestLog::Log(string logMessage)
{
    //this->logString->append(logMessage);

}

我缺少什么？我需要添加std c ++库到我的targetS吗？与搜索标题路径相关的东西？

What am I missing? Do I need to add std c++ library to my targetS? Something related to Search Header Paths?

我只需要使用字符串类型。

I just need to use string type.
