在uitableview中的单元格上添加单选按钮

我正面临着 uitableview 单元格中自定义单选按钮的问题我正在使用下面的代码，我想为 didselectrowatindexpath 和单选按钮发送器操作设置相同的操作，以便我可以从所有选择一个单元格并取消选择表格视图中的所有其他单元格 . 在 tableview 我想显示所有ipod音乐库歌曲，用户可以一次从所有歌曲中选择一首 .

        if (cell == nil)
        {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] ;
            cell.selectionStyle = UITableViewCellSelectionStyleGray;
            cell.detailTextLabel.textColor = [UIColor darkGrayColor];
            [cell setAccessoryType:UITableViewCellAccessoryNone];
        } 

    cell.backgroundColor = [UIColor whiteColor];
    cell.textLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:16];
    cell.textLabel.textColor = [UIColor blackColor];
    cell.imageView.image = [UIImage imageNamed:@"cbimg_unselected.png"];

    MPMediaItem *temp1 = [self.sectionedArtistsArray objectAtIndex:indexPath.row];
    cell.textLabel.text = [temp1 valueForProperty:MPMediaItemPropertyTitle];
