extern NSString *const JCTImageDownloadGroupId;

NSMutableArray *downloadList = [NSMutableArray array];

    item.groupId = JCTImageDownloadGroupId;
    item.downloadUrl = [self urlList][index];
    item.downloadFilePath = [JCDownloadUtilities filePathWithFileName:[item.downloadUrl lastPathComponent] folderName:@"downloadImages"];
    JCDownloadOperation *operation = [JCDownloadOperation operationWithItem:item];
