如何使用 App 沙盒应用程序在 MAC 卷中查找文件和文件夹

我正在 MAC(10.9) 上创建一个沙盒应用程序.当应用程序沙盒化关闭时，我可以从任何路径获取文件和文件夹.但是当我启用 App Sand-boxed 时，它不会从任何路径访问任何文件和文件夹.使用 Qt 5.0 关闭 App Sand-boxed 时，从路径(/Volumes/DriveName"或/"等)获取文件和文件夹

I am creating a sand-boxed application on MAC(10.9).When App Sand-boxed is off then i am able to get files and folders from any path. But when I does App Sand-boxed enabled it's not accessing any files and folders from any path. Getting file and folder from path ("/Volumes/DriveName" or "/" etc.) when App Sand-boxed is off using Qt 5.0

// for folders

    QStringList folderlist;
       QDir curDir = QDir(path);   
       curDir.setFilter(QDir::Dirs);
       QFileInfoList list = curDir.entryInfoList();
       for(;<list.size;)
        {
             QfileInfo fileInfo = list.at(i);
             folderList << fileInfo.filePath();
        }
    // for files
    QStringList filelist;
        QDirIterator dirIn(path,filterfiles,QDir::AllEnteries);
        while(dirIn.hasnext())
    {
     dirIn.next();
    QfileInfo fileInfo = dirIn.fileInfo();
             filelist<< fileInfo.filePath();
    }

    What i do same when App sand-boxed is enabled?
