NSDictionary *dic = dataArr[indexPath.row];

//    cell.textLabel.text = dic[@"name"];

//    cell.detailTextLabel.text = dic[@"age"];

// 原始搜索结果字符串.

NSString *originResult = dataArr[indexPath.row][@"name"];

// 获取关键字的位置

NSRange range = [originResult rangeOfString:text];

// 转换成可以操作的字符串类型.

NSMutableAttributedString *attribute = [[NSMutableAttributedString alloc] initWithString:originResult];

// 添加属性(粗体)

[attribute addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:15] range:range];

// 关键字高亮

[attribute addAttribute:NSForegroundColorAttributeName value:RGB(255, 141, 10) range:range];

// 将带属性的字符串添加到cell.textLabel上.

[cell.textLabel setAttributedText:attribute];

cell.textLabel.text = dic[@"name"];
