在具有可重复使用单元格的表格单元格中按下按钮

Question

我正在努力解决以下问题。

我有一张船的选项表视图。每个选项（单元格）都有一个名称，一个价格和一个按钮，用于指示是否已选择该选项（参见附件截图） -

问题在于，当我点击第1节中的几个选项时，我也得到了最后一节中单元格的button_pressed状态。可能这是因为细胞被重复使用了吗？

这是在点击单元格时调用的函数，用于添加选项。

- (IBAction)cellButtonSelection:(id)sender {

float prezzoParziale;

UIButton * button = sender;
//NSLog(@"%@",button.superview.superview);
if ([button.superview.superview isKindOfClass:[CellOptions class]] ) {

    CellOptions * cellOpt =(CellOptions *)button.superview.superview;

    //BOOL selectionState = NO;
    cellOpt.selected =! cellOpt.selected;

    if(cellOpt.selected){
        //UIButton *button = cellOpt.button1;
        [button setImage:[UIImage imageNamed:@"checkedButton.png"] forState:UIControlStateNormal];
        prezzoParziale = [cellOpt.label2.text floatValue];
        [accessoriSelezionati addObject:cellOpt.label1.text];
        [accessoriSelezionatiPrezzi addObject: cellOpt.label2.text];

        NSLog(@"stampa: %@", accessoriSelezionati);


    }else{
        //UIButton *button = cellOpt.button1;
        [button setImage:[UIImage imageNamed:@"uncheckedButton.png"] forState:UIControlStateNormal];
        prezzoParziale = [cellOpt.label2.text floatValue] * -1;
        [accessoriSelezionati removeObject:cellOpt.label1.text];
        [accessoriSelezionatiPrezzi removeObject: cellOpt.label2.text];

    }


 [self updateTotal:prezzoParziale]; }

和.....

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

        CellOptions * cellOpt;
     cellOpt = [tableView dequeueReusableCellWithIdentifier:CellOption forIndexPath:indexPath];
     cellOpt.label1.text = [[[accessoriXtipologia objectForKey:tipologia] objectAtIndex:indexPath.row] valueForKey:@"nome"];
    cellOpt.label2.text = [[[[accessoriXtipologia objectForKey:tipologia] objectAtIndex:indexPath.row] valueForKey:@"prezzo"] stringValue];

    return cellOpt;

    }

编辑：现在它正在运作

在cellForRowAtIndexPath中添加：

cellOpt.selected = [accessoriSelezionati containsObject:cellOpt.label1.text];



            if (cellOpt.selected) {

                [cellOpt.button1 setImage:[UIImage imageNamed:@"checkedButton.png"] forState:UIControlStateNormal];
            }

            else {



            [cellOpt.button1 setImage:[UIImage imageNamed:@"uncheckedButton.png"] forState:UIControlStateNormal];

            }

            return cellOpt;

是的，这是由于细胞重用。在cellForRowAtIndexPath中，除了设置标签之外，您还必须通过执行以下操作来设置所选状态：

cellOpt.selected = [accessoriSelezionati containsObject:cellOpt.label1.text];
