iPhone中带有CheckBox的TableView行

Question

I'm developing an application and am stuck on one thing. I've tried to resolve my problem on my own, but couldn't figure it out. If some one knows how to solve this, please help me out.

I created one UITableView with a checkbox in every row. When any checkbox is tapped I want only that checkbox selected, but currently only last check box is selected. I've provided my current code below, please let me know if you see anything that should be changed.

Thanks.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
    }

    cell.textLabel.text = [selectPlayer objectAtIndex:indexPath.row];
    checkboxButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 8, 25, 25)];
    checkboxButton.tag = indexPath.row;
    [checkboxButton setTitle:nil forState:UIControlStateNormal];
    [checkboxButton addTarget:self action:@selector(checkboxButton:)forControlEvents:UIControlEventTouchUpInside];

    [checkboxButton addSubview:checkImage];
    cell.accessoryView = checkboxButton; 
    return cell;
}

-(void)checkboxButton:(id)sender {
    NSIndexPath *indexPath = [selectTableView indexPathForCell:(UITableViewCell *)[[sender superview] superview]];
    switch (indexPath.section) {
        case 0:
            switch (indexPath.row) {
                case 0:
                    [checkImage setImage:[UIImage imageNamed:@"checkbox-checked.png"]];
                    NSLog(@"button pressed at section %d and %d row", indexPath.section, indexPath.row);
                    break;

                case 1:
                    //[checkImage setImage:[UIImage imageNamed:@"checkbox-checked.png"]];
                    NSLog(@"button pressed at section %d and %d row", indexPath.section, indexPath.row);
                    break;

                default:
                    break;
            }
            break;

        default:
            break;
    }
}

Answer 1

I think your problem is that you are not using the right method, I think you need to implement the

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *) indexPath{ }

here you have the indexPath for the selected row, and the instance of the tableView, all you need to do is instantiate the TableViewCell and check your checkmark.

声明cellForRowAtIndexPath方法内的复选框按钮：

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