请问如何将一个字符串从GBK转到UTF-8？

[setimouse]

请问Objective-C中如何进行字符串编码转换？
对于GBK的网页，希望将其内容转换成UTF-8。
PHP中处理非常简单，但是Objective-C里却一直找不到办法。

请问有没有办法来进行转码呢？

谢谢！

调用：GBKToUTF8(str对象, “gb2312”, “utf-8”);

int GBKToUTF8(std::string & gbkStr, const char* toCode, const char* fromCode)
{

iconv_t iconvH;
iconvH = iconv_open(fromCode, toCode);
if (iconvH == 0)
{
return -1;
}

const char* strChar = gbkStr.c_str();
const char** pin = &strChar;
size_t strLength = gbkStr.length();
char* outbuf = (char*) malloc(strLength*4);
char* pBuff = outbuf;

memset( outbuf, 0, strLength*4);
size_t outLength = strLength*4;
if (-1 == iconv(iconvH, pin, &strLength, &outbuf, &outLength))
{
iconv_close(iconvH);
return -1;
}
gbkStr = pBuff;
iconv_close(iconvH);
return 0;
}
