私のアプリケーションでは、NSMutableArray で質問をして、tableView 行に表示しています。各質問の下に 2 つのボタン (tableView 行ボタン) を配置しました。YES ボタンと NO ボタンを押すと、TableRow の色がそれぞれ緑と黄色に変わります。
問題は、特定の行のボタンを押した後、行が緑色に変わることです。しかし、スクロールした後、不要なセルも緑/黄色に変わります。
以下のコードを確認して提案してください

contentView.hidden = YES;

UIButton *YesButton;

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone; //cell bg
//self.myChklist.backgroundColor = [UIColor clearColor];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
QuestLabel = [[UILabel alloc] initWithFrame:CGRectMake(5,5,768,0)];
//some logic code
[cell.contentView addSubview:QuestLabel];
NSString *titleString = [buildingQuest objectAtIndex:indexPath.row] ;
