我正在进行调查，例如显示问题和答案的项目。我tableView用标签和按钮显示它们。但是现在我不知道如何处理选择的每个答案。

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 NSMutableArray *sectionItems=[self.finalarray objectAtIndex:indexPath.section];
    int n=[sectionItems count];

    NSString *question = [NSString stringWithFormat:@"%@",[[sectionItems  objectAtIndex:indexPath.row] objectForKey:@"Question"]];
    CGSize constraint1 = CGSizeMake(320, 2000.0f);
    CGSize size1 = [question sizeWithFont: [UIFont fontWithName:@"Helvetica-Bold" size:14] constrainedToSize:constraint1 lineBreakMode:NSLineBreakByWordWrapping];
    lblQuestion = (UILabel *)[hlcell viewWithTag:1];
    lblQuestion.text = [NSString stringWithFormat:@"%@",question];

    lblQuestion. numberOfLines=0;
    lblQuestion.frame = CGRectMake(10,15, size1.width, size1.height);

 UIButton *btTemp1 = [[UIButton alloc]initWithFrame:CGRectMake(10, lblQuestion.frame.origin.y+lblQuestion.frame.size.height,10, 15)];
        [btTemp1 addTarget:self action:@selector(radioButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
        btTemp1.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
        [btTemp1 setImage:[UIImage imageNamed:@"radio_button_off.png"] forState:UIControlStateNormal];
        [btTemp1 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        btTemp1.titleLabel.font =[UIFont systemFontOfSize:14.f];
        [hlcell.contentView addSubview:btTemp1];



        NSLog(@"%@",[[sectionItems  objectAtIndex:1] objectForKey:@"Description"]);
        NSString *option1 = [NSString stringWithFormat:@"%@",[[sectionItems  objectAtIndex:1] objectForKey:@"Description"]];
        CGSize constraint2 = CGSizeMake(320, 2000.0f);
        CGSize size2 = [option1 sizeWithFont: [UIFont fontWithName:@"Helvetica-Bold" size:14] constrainedToSize:constraint2 lineBreakMode:NSLineBreakByWordWrapping];
        lblOption1 = (UILabel *)[hlcell viewWithTag:1];
        lblOption1.text = [NSString stringWithFormat:@"%@",option1];
        [lblOption1 setNumberOfLines:0];
        lblOption1.frame = CGRectMake(30,lblQuestion.frame.origin.y+lblQuestion.frame.size.height, size2.width, size2.height);
        [hlcell.contentView addSubview:lblanswers];

        UIButton *btTemp2 = [[UIButton alloc]initWithFrame:CGRectMake(10, lblOption1.frame.origin.y+lblOption1.frame.size.height,10, 15)];
        [btTemp2 addTarget:self action:@selector(radioButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
        btTemp2.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
        [btTemp2 setImage:[UIImage imageNamed:@"radio_button_off.png"] forState:UIControlStateNormal];
        [btTemp2 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        btTemp2.titleLabel.font =[UIFont systemFontOfSize:14.f];
        [hlcell.contentView addSubview:btTemp2];



        NSString *option2 = [NSString stringWithFormat:@"%@",[[sectionItems  objectAtIndex:2] objectForKey:@"Description"]];
        CGSize constraint3 = CGSizeMake(320, 2000.0f);
        CGSize size3 = [option2 sizeWithFont: [UIFont fontWithName:@"Helvetica-Bold" size:14] constrainedToSize:constraint3 lineBreakMode:NSLineBreakByWordWrapping];
        lblOption2 = (UILabel *)[hlcell viewWithTag:2];
        lblOption2.text = [NSString stringWithFormat:@"%@",option2];
        [lblOption2 setNumberOfLines:0];
        lblOption2.frame = CGRectMake(30,lblOption1.frame.origin.y+lblOption1.frame.size.height, size3.width, size3.height);
        [hlcell.contentView addSubview:lblOption2];

return hlcell;
}

我有 10 个问题，我怎样才能在每个部分中选择答案并存储它。我无法引用 indexpath。方法中的部分radioButtonClicked。如果我radiobutton在一个部分中选择一个，它会被启用，而其他部分会被禁用。但是，如果我radiobutton在其他部分检查所有radiobuttons先前检查的内容也将被禁用。如何单独处理一个部分的单选按钮选择。

将单击的 indexPath 存储在字典中，并根据所选值管理单元格显示。cellForRowAtIndexPath根据存储的值，在创建它们时将它们设置为选中。喜欢：

if([[selectedRows valueForKey:stringRepresentationOfIndexPath] boolValue] == YES)
  [btTemp1 setSelected:YES];

编辑： selectedRows是包含所选行数据的字典，在 中更新它didSelectRowAtIndexPath，或单击但单击（如果您这样做）。
