ios - 在 UITableView ios 的每个部分中选择一行？

Question

场景:

我在一个 UITableView 中制作了 2 个部分，用户需要在每个部分中选择一行，如下面的屏幕截图所示。

预期结果:1. 用户应该能够在每个部分中选择一行

现在的结果:1. 在我选择了一个部分中的行之后，然后当我在第二部分中选择该行时，第一个选择消失了。

这是我的代码:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // Uncheck the previous checked row

    long sec=indexPath.section;
     if(sec==0){
    if(self->checkedIndexPath)
    {
        UITableViewCell* uncheckCell = [tableView
                                        cellForRowAtIndexPath:self->checkedIndexPath];
        uncheckCell.accessoryType = UITableViewCellAccessoryNone;
    }
    if([self->checkedIndexPath isEqual:indexPath])
    {
        self->checkedIndexPath = nil;
    }
    else
    {
        UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
        self->checkedIndexPath = indexPath;
    }}

    if(sec==1){

        if(self->checkedIndexPath)
        {
            UITableViewCell* uncheckCell = [tableView
                                            cellForRowAtIndexPath:self->checkedIndexPath];
            uncheckCell.accessoryType = UITableViewCellAccessoryNone;
        }
        if([self->checkedIndexPath isEqual:indexPath])
        {
            self->checkedIndexPath = nil;
        }
        else
        {
            UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
            self->checkedIndexPath = indexPath;
        }

    }

}

感谢您的帮助。

这是最简单的方法。最后我找到了解决方案。它对我有用，希望它对你有用。声明这些

@interface ViewController ()
{
    int selectedsection;
    NSMutableArray *selectedindex;

}

替换 didSelectRowAtIndexPath 如下:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // Uncheck the previous checked row

    NSIndexPath *selectedIndexPath = [tableView indexPathForSelectedRow];

        if(self.checkedIndexPath)

        {

            for (int i=0; i<[selectedindex count]; i++) {

                NSIndexPath *temp= [selectedindex objectAtIndex:i];
                if (temp.section==selectedIndexPath.section) {
                    UITableViewCell* uncheckCell = [tableView
                                                    cellForRowAtIndexPath:temp];
                    uncheckCell.accessoryType = UITableViewCellAccessoryNone;

                }
            }

            NSInteger numb= [tableView numberOfRowsInSection:selectedIndexPath.section];

            if (selectedsection==selectedIndexPath.section) {


            UITableViewCell* uncheckCell = [tableView
                                            cellForRowAtIndexPath:self.checkedIndexPath];
            uncheckCell.accessoryType = UITableViewCellAccessoryNone;

            }
        }



        if([self.checkedIndexPath isEqual:indexPath])
        {
            for (int i=0; i<[selectedindex count]; i++) {

                NSIndexPath *temp= [selectedindex objectAtIndex:i];
                if (temp.section==selectedIndexPath.section) {
                    UITableViewCell* uncheckCell = [tableView
                                                    cellForRowAtIndexPath:temp];
                    uncheckCell.accessoryType = UITableViewCellAccessoryNone;

                }
            }


           self.checkedIndexPath = nil;
        }
        else
        {
            for (int i=0; i<[selectedindex count]; i++) {

                NSIndexPath *temp= [selectedindex objectAtIndex:i];
                if (temp.section==selectedIndexPath.section) {
                    UITableViewCell* uncheckCell = [tableView
                                                    cellForRowAtIndexPath:temp];
                    uncheckCell.accessoryType = UITableViewCellAccessoryNone;

                }
            }

            UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
            self.checkedIndexPath = indexPath;
            [selectedindex addObject:indexPath];
            selectedsection=indexPath.section;

            NSLog(@"check");
        }
