求助...有木有高手帮忙将一段java代码转成oc可以用的(oc,c,c++),感谢
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

public class KrcText
{
  private static final char[] miarry = { '@', 'G', 'a', 'w', '^', '2', 't',
'G', 'Q', '6', '1', '-', 'Î', 'Ò', 'n', 'i' };
   
  public static void main(String[] args) throws IOException
  {
  String filenm = "";//krc文件的全路径加文件名
  System.out.println(new KrcText().getKrcText(filenm));
  }

  /**
  * 
  * @param filenm krc文件路径加文件名
  * @return krc文件处理后的文本
  * @throws IOException
  */
  public String getKrcText(String filenm) throws IOException
{
File krcfile = new File(filenm);
byte[] zip_byte = new byte[(int) krcfile.length()];
FileInputStream fileinstrm = new FileInputStream(krcfile);
byte[] top = new byte[4];
fileinstrm.read(top);
fileinstrm.read(zip_byte);
int j = zip_byte.length;
for (int k = 0; k < j; k++)
{
int l = k % 16;
int tmp67_65 = k;
byte[] tmp67_64 = zip_byte;
tmp67_64[tmp67_65] = (byte) (tmp67_64[tmp67_65] ^ miarry[l]);
}
String krc_text = new String(ZLibUtils.decompress(zip_byte), "utf-8");
return krc_text;
}
}
红色部分的这个方法，看看有木有办法转换成iphone上可以直接使用的。。多谢^^!~这个代码是解析krc歌词用的

------解决方案--------------------

C/C++ code

void getKrcText(const char *pszFilePath)
{
    char szMiarry[] = { '@', 'G', 'a', 'w', '^', '2', 't','G', 'Q', '6', '1', '-', 'Î', 'Ò', 'n', 'i' };
    FILE *fp = ::fopen(pszFilePath, "rb");
    
    ::fseek(fp, SEEK_SET, SEEK_END);
    int  nFileLength = ::ftell(fp);
    ::fseek(fp, SEEK_SET, SEEK_SET);

    char *pTop = new char[4];
    char *pFileData = new char[nFileLength-4];

    ::fread(pTop, 1, 4, fp);
    int nRead = 0;
    for ( ; nRead < nFileLength - 4; )
    {
        int nCurRead = ::fread(pFileData + nRead, 1, nFileLength - 4 - nRead, fp);
        nRead += nCurRead;
    }

    for ( int k = 0; k < nFileLength - 4; ++k )
    {
        int j = k % 16;        
        pFileData[k] ^= szMiarry[j];
    }

    // zip解压，需要专门的解压库
