UITableView をスクロールすると、テーブルビューのセルが自動的にオフになります。しかし、完了ボタンを押すと、選択された行が表示されます。なぜこれが起こっているのか理解できません。

ここに画像の説明を入力

私のTableviewコードは以下の通りです：

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
idArray = [[NSMutableArray alloc]init];

NSLog(@"Cat Array : %@",catArray);
isSelectAllBtnClicked = NO;

serviceArray = [[NSArray alloc]initWithObjects:@"Anal", @"Cuffed", @"Foreplay",     @"Masturbation", @"Scat", @"Blindfolded",@"Deep throat", @"French Kissing", @"Missionary", @"Shower for 2", @"Bottom", @"Dinner Date", @"Full Bondage", @"Mutual Masturbation", @"Spanking", @"Boy on Boy", @"Dirty Talk",@"Girl on Girl", @"On top", @"Strap on", @"Choking", @"Doggy", @"Girlfriend Experience", @"Oral", @"Striptease", @"CIM", @"Dominate", @"Golden Shower",@"Oral Mutual", @"Submissive", @"COB", @"Fantasy", @"Kissing", @"Overnight", @"Top", @"COF", @"Fetish", @"Light Bondage", @"Rim me",@"Touching", @"Couples", @"Fisting", @"Lingerie", @"Rim you", @"Toys for me", @"Cuddling", @"Foot fetish", @"Massage", @"Role Play", @"Toys for you", nil];

[myTableView reloadData];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *reuseIdentifier = @"reuseIdentifier";
        UITableViewCell *cell = [[UITableViewCell alloc]init];

        if (cell != NULL) 
        {
            cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseIdentifier];
        }
        cell.selectionStyle = UITableViewCellEditingStyleNone;
        cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"list_row_bg.png"]] autorelease];

        UILabel *catListLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 310, 20)];
        NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:@"service"];

        if ([strValue isEqualToString:@"service"]) 
        {
            catListLbl.text = [serviceArray objectAtIndex:indexPath.row];
            topHaderLabel.text = @"Choose Services";
        }
        else
        {
            catListLbl.text = [catArray objectAtIndex:indexPath.row]; 
            topHaderLabel.text = @"Choose Category";
        }

        catListLbl.backgroundColor = [UIColor clearColor];
        [cell addSubview:catListLbl];

        if (isSelectAllBtnClicked) {
            UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
            [unCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox_check.png"] forState:UIControlStateNormal];
            unCheckBtn.tag = indexPath.row + 200;
            //NSLog(@"%i",unCheckBtn.tag);
            [cell addSubview:unCheckBtn];

            [myTableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
            [self tableView:myTableView didSelectRowAtIndexPath:indexPath];

        }
        else {

            [cell addSubview:unCheckBtn];
        }

        return cell;

前もって感謝します。

テーブルをスクロールするたびに

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

メソッドが実行され、この行が以前に選択されたかどうかを判断できる条件について言及していません。indexPath.row とともに条件を挿入し、以前に選択されているかどうかを確認する必要があります

isSelectAllBtnClicked 値が 0 になるたびにテーブルビューをスクロールすると、ボタンが変更されるたびにこのようになります。

新しいセルが作成されるたびにテーブルをスクロールするときは、それを避けてください

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        NSString *CellIdentifier = [NSString stringWithFormat:@"%d",indexPath.row];
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
        cell.selectionStyle = UITableViewCellEditingStyleNone;
        cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"list_row_bg.png"]] autorelease];

        UILabel *catListLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 310, 20)];
        NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:@"service"];

        if ([strValue isEqualToString:@"service"]) 
       {
          catListLbl.text = [serviceArray objectAtIndex:indexPath.row];
          topHaderLabel.text = @"Choose Services";
       }
        else
       {
        catListLbl.text = [catArray objectAtIndex:indexPath.row]; 
        topHaderLabel.text = @"Choose Category";
        }

       catListLbl.textColor = [UIColor colorWithRed:244/255.0 green:29/255.0 blue:94/255.0 alpha:1.0];
      catListLbl.backgroundColor = [UIColor clearColor];
      [cell addSubview:catListLbl];

       if (isSelectAllBtnClicked) {
        UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)]; 
        [unCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox_check.png"] forState:UIControlStateNormal];
        unCheckBtn.tag = indexPath.row + 200;
        //NSLog(@"%i",unCheckBtn.tag);
        [cell addSubview:unCheckBtn];

        [myTableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
        [self tableView:myTableView didSelectRowAtIndexPath:indexPath];

    }
    else {
        UIButton *unCheckBtn = [[UIButton alloc]initWithFrame:CGRectMake(270, 10, 20, 20)];
        [unCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox.png"] forState:UIControlStateNormal];
        unCheckBtn.tag = indexPath.row + 200;
        //NSLog(@"%i",unCheckBtn.tag);
        [cell addSubview:unCheckBtn];
    }
        }

    }
