    NSAttributedString *commentCountAttrString = [[NSAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@",@(commentCount)] attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:],NSForegroundColorAttributeName:[[TinyVideo5Theme yy5Theme] getColorWithColorString:COLOR_4]}];

    NSMutableAttributedString *commentString = [[NSMutableAttributedString alloc] init];

    [commentString appendAttributedString: commentAttrString];
