{
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 40)];
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, tableView.frame.size.width, 20)];
    label.font = [UIFont systemFontOfSize:16.0f];  //UILabel的字体大小
    label.numberOfLines = 0;  //必须定义这个属性，否则UILabel不会换行
    label.textColor = CR_RGBCOLOR(170, 170, 170);
    label.textAlignment = NSTextAlignmentLeft;  //文本对齐方式
    [label setBackgroundColor:[UIColor clearColor]];
    label.text = self.sectionTitles[section];
    [headerView setBackgroundColor:[UIColor clearColor]];
    [headerView addSubview:label];
    return  headerView;
}

    NSUInteger row = indexPath.row;
    
    if(section == 1){
        if (row == 0) {
            [self recommendToFriends];
            [tableView deselectRowAtIndexPath:indexPath animated:YES];
        }else if(row == 1){
