Question

我正在拥有一个UITableview，因为它有三个按钮，并且按钮具有良好的工作条件。我的问题是当我选择任何按钮图像更改为所选图像时。但是当我滚动表格视图时，所选图像会变为普通图像。我想在表格视图中保存所选内容。我看到很多堆栈溢出，但它没有帮助我。任何人都帮帮我。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = [NSString stringWithFormat:@"S%1dR%1d",indexPath.section,indexPath.row];
CustomizedCellView *cell = (CustomizedCellView *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

cell = [table dequeueReusableHeaderFooterViewWithIdentifier:CellIdentifier];

if (cell == nil) {
    cell = [[CustomizedCellView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}


button1 = [UIButton buttonWithType:UIButtonTypeCustom];
    button1.frame = CGRectMake(80, 27, 36, 36);
    [button1 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"l"ofType:@"png"]] forState:UIControlStateNormal];
    [button1 setImage:[UIImage imageNamed:@"lblue.png"]
             forState:UIControlStateSelected];
    [button1 addTarget:self action:@selector(radiobtn4:) forControlEvents:UIControlEventTouchUpInside];

    button1.tag=1;
    [cell.contentView addSubview:button1];
button2 = [UIButton buttonWithType:UIButtonTypeCustom];
    button2.frame = CGRectMake(160, 27, 36, 36);
    [button2 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"e"ofType:@"png"]] forState:UIControlStateNormal];
    [button2 setImage:[UIImage imageNamed:@"eblue.png"]
             forState:UIControlStateSelected];

    [button2 addTarget:self action:@selector(radiobtn4:) forControlEvents:UIControlEventTouchUpInside];
    [cell.contentView addSubview:button2];
    button2.tag=3;


    button3 = [UIButton buttonWithType:UIButtonTypeCustom];
    button3.frame = CGRectMake(240, 27, 36, 36);
    [button3 setImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"v"ofType:@"png"]] forState:UIControlStateNormal];
    [button3 setImage:[UIImage imageNamed:@"vblue.png"]
             forState:UIControlStateSelected];

    [button3 addTarget:self action:@selector(radiobtn4:) forControlEvents:UIControlEventTouchUpInside];
    [cell.contentView addSubview:button3];
    button3.tag=2;

- (void)radiobtn4:(UIButton *)sender

{
    UITableViewCell *cell=(UITableViewCell *)sender.superview;
    if(sender.selected == NO)
    {

        if(sender.tag==1){

            UIButton *otherButton=(UIButton *)[cell viewWithTag:1];
            otherButton.selected=YES;
            UIButton *other=(UIButton *)[cell viewWithTag:2];
            other.selected=NO;

        }else if(sender.tag==2){
            UIButton *otherButton=(UIButton *)[cell viewWithTag:2];
            otherButton.selected=YES;
            UIButton *other=(UIButton *)[cell viewWithTag:1];
            other.selected=NO;


        } else if(sender.tag == 3)
        {
            UIButton *otherButton=(UIButton *)[cell viewWithTag:3];
            otherButton.selected=YES;

        }

    } else  if(sender.selected == YES)

    {
        if(sender.tag==1){
            UIButton *otherButton=(UIButton *)[cell viewWithTag:1];
            [otherButton setImage:[UIImage imageNamed:@"l.png"]
                         forState:UIControlStateNormal];
            otherButton.selected=NO;


        }else if(sender.tag==2){
            UIButton *otherButton=(UIButton *)[cell viewWithTag:2];
            [otherButton setImage:[UIImage imageNamed:@"v.png"]
                         forState:UIControlStateNormal];
            otherButton.selected=NO;

        }  else if(sender.tag == 3)
        {
            UIButton *otherButton=(UIButton *)[cell viewWithTag:3];
            [otherButton setImage:[UIImage imageNamed:@"e.png"]
                         forState:UIControlStateNormal];
            otherButton.selected=NO;

        }

    }

}

以上是我的编码，我想使用任何数组来存储所选图像，我该怎么做，请帮我编码。
