tableViewCell之再操作

在开发中经常会遇到这种需要删除cell的操作，
代码如下

-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
    return UITableViewCellEditingStyleDelete;//手势滑动删除

}
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath

{
    if (editingStyle ==UITableViewCellEditingStyleDelete) {
        // 1.从数组中删除数据
        [_students removeObject:_findStudent];//这个为要删除的数据，_findStudent为数据类创建的对象
        //再将此条cell从列表删除,_tableView为列表
        [_tableView beginUpdates];
        [_tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
        //刷新数据
        [_tableView reloadData];
}

可以写

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    return [[UIView alloc] init];
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    return [[UIView alloc] init];
}
控制两个cell之间的间距

自定义cell的两种方式 if一种，else一种
第一种注意把添加的控件放在判空初始化cell外面

if(indexPath.section == 1){
        UITableViewCell  *cell2 = [_tableView dequeueReusableCellWithIdentifier:@"cell2"];
        if(cell2 == nil){
            cell2 = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell2"];
        }
            UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(300, 10, 100, 30)];
            label1.text = @"share小白";

            UILabel *label2 = [[UILabel alloc] initWithFrame:CGRectMake(210, 80, 100, 30)];
            label2.text = @"15分钟前";

            UIImageView *image1 = [[UIImageView alloc] initWithFrame:CGRectMake(10, 0, 170, 150)];
            image1.image = [UIImage imageNamed:@"list_img1"];

            UIButton *btn1 = [[UIButton alloc] init];

            [btn1 setTitle:@"101" forState:UIControlStateNormal];

            btn1.frame = CGRectMake(200, 110, 70, 30);
            [btn1 setImage:[UIImage imageNamed:@"爱心"] forState:UIControlStateNormal];
            [btn1 setImage:[UIImage imageNamed:@"真心"] forState:UIControlStateSelected];
            [btn1 addTarget:self action:@selector(press12:) forControlEvents:UIControlEventTouchUpInside];


            cell2.selectionStyle = UITableViewCellSelectionStyleNone;

            [cell2.contentView addSubview:label1];
            [cell2.contentView addSubview:label2];
            [cell2.contentView addSubview:image1];
            [cell2.contentView addSubview:btn1];
        return cell2;
    }  
    else{
        QSTTableViewCell *cell3 = [_tableView dequeueReusableCellWithIdentifier:@"cell3" forIndexPath:indexPath];

        NSArray *array1 = [NSArray arrayWithObjects:@"国外画册欣赏",@"collection扁平设计",@"版式整理术", nil];
        NSArray *array2 = [NSArray arrayWithObjects:@"share小王",@"share小吕",@"share小王",nil];
        NSArray *array3 = [NSArray arrayWithObjects:@"平面设计-画册设计",@"平面设计-海报设计",@"平面设计", nil];
        NSArray *array4 = [NSArray arrayWithObjects:@"15分钟前",@"16分钟前",@"17分钟前",nil];
        NSArray *array5 = [NSArray arrayWithObjects:@"102",@"26",@"20",nil];
        NSArray *array6 = [NSArray arrayWithObjects:@"100",@"15",@"10",nil];
        NSArray *array7 = [NSArray arrayWithObjects:@"103",@"28",@"50",nil];

        cell3.titleLabel.text = array1[indexPath.row];
        cell3.detailLabel.text = array2[indexPath.row];
        cell3.label1.text = array3[indexPath.row];
        cell3.label2.text = array4[indexPath.row];

        [cell3.btn1 setTitle:array5[indexPath.row] forState:UIControlStateNormal];
        [cell3.btn2 setTitle:array6[indexPath.row] forState:UIControlStateNormal];
        [cell3.btn3 setTitle:array7[indexPath.row] forState:UIControlStateNormal];

        NSArray *array8 = [NSArray arrayWithObjects:@"list_img2",@"list_img3",@"list_img4",nil];
        cell3.newsImage.frame = CGRectMake(10, 0, 170, 140);
        cell3.newsImage.image = [UIImage imageNamed:array8[indexPath.row]];
        cell3.spaceImage.image = [UIImage imageNamed:@" "];
        UISwipeGestureRecognizer *swipeRightOrange = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(slideToRightWithGestureRecognizer:)];
        // 滑动方向
        swipeRightOrange.direction = UISwipeGestureRecognizerDirectionRight;

        [cell3.newsImage addGestureRecognizer:swipeRightOrange];
        return cell3;
