したがって、5行あり、選択すると、行番号を含む整数が2番目のView Controllerに渡されます。

各数値にはアイテムを含む独自の配列があり、指定された行のアイテムの量を返す必要があります。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"MasterCell";

    MasterCell *cell = (MasterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];


if (radInt == 0) {
     cell.textLabel.text = @"LM";
     NSLog(@"My return should have been LM");

}
if (radInt == 1) {
    cell.textLabel.text = @"Restauranger";
    NSLog(@"My return should have been Rest");
}
    if (radInt == 2) {
        cell.textLabel.text = [shoppingArray objectAtIndex:indexPath.row];
    }
    if (radInt == 3) {
        cell.textLabel.text = [annatArray objectAtIndex:indexPath.row];
    }

    //cell.textLabel.text = [listData objectAtIndex:[indexPath row]];
    cell.imageView.image = [UIImage imageNamed:@"tab-icon1.png"];
    cell.accessoryType = UITableViewCellAccessoryNone;


    return cell;
}

これはテスト用のコードであり、機能しません。NSLOG は正常に動作しますが、データは単に更新されません...何が間違っていますか? 毎回 LM を Nslogs しますが、選択された行 (radInt) であるログにも 1 があります。

新しいアプローチ

static NSString *CellIdentifier = @"MasterCell";
    MasterCell *cell = (MasterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell==nil)
        cell = [[MasterCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

    if (radInt == 0) {
        cell.textLabel.text = @"LM";
        NSLog(@"My return should have been LM");

    }
    else if (radInt == 1) {
        cell.textLabel.text = @"Restauranger";
        NSLog(@"My return should have been Rest");
    }
    else if (radInt == 2) {
        cell.textLabel.text = [shoppingArray objectAtIndex:indexPath.row];
    }
    else if (radInt == 3) {
        cell.textLabel.text = [annatArray objectAtIndex:indexPath.row];
    }

    else {
        cell.textLabel.text = @"Noes";
    }


    //cell.textLabel.text = [listData objectAtIndex:[indexPath row]];
    cell.imageView.image = [UIImage imageNamed:@"tab-icon1.png"];
    cell.accessoryType = UITableViewCellAccessoryNone;

    return cell;

前の景色----

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    SecondViewController *enjoy = [[SecondViewController alloc] init];
    if ([[array objectAtIndex:indexPath.row] isEqual:@"Livsmedel"]) {
        [enjoy setTitle:[array objectAtIndex:indexPath.row]];
        enjoy.radInt = 0;
        NSLog(@"0");
    }

    if ([[array objectAtIndex:indexPath.row] isEqual:@"Restauranger"]) {
        [enjoy setTitle:[array objectAtIndex:indexPath.row]];
        enjoy.radInt = 1;
        NSLog(@"1");
    }

    if ([[array objectAtIndex:indexPath.row] isEqual:@"Shopping"]) {
        [enjoy setTitle:[array objectAtIndex:indexPath.row]];
        enjoy.radInt = 2;

    }
    if ([[array objectAtIndex:indexPath.row] isEqual:@"Annat"]) {
        enjoy.radInt = 3;
    }

    [self performSegueWithIdentifier:@"main" sender:self];
}

ストーリーボードのセグエをセルから次のコントローラーに接続する場合、実際には didSelectRowAtIndexPath: を実装する必要はありません。実装する必要があるのは、prepareForSegue: です。コードは次のようになります。

- (void)prepareForSegue:(UIStoryboardSegue *) segue sender:(id) sender
{
    NSInteger row = [self.tableView indexPathForSelectedRow].row;
    SecondViewController *enjoy = segue.destinationViewController;
    if ([[array objectAtIndex:row] isEqual:@"Livsmedel"]) {
        [enjoy setTitle:[array objectAtIndex:row]];
        enjoy.radInt = 0;
        NSLog(@"0");
    }

    if ([[array objectAtIndex:row] isEqual:@"Restauranger"]) {
        [enjoy setTitle:[array objectAtIndex:row]];
        enjoy.radInt = 1;
        NSLog(@"1");
    }

    if ([[array objectAtIndex:row] isEqual:@"Shopping"]) {
        [enjoy setTitle:[array objectAtIndex:row]];
        enjoy.radInt = 2;

    }
    if ([[array objectAtIndex:row] isEqual:@"Annat"]) {
        enjoy.radInt = 3;
    }
}
