Call of UIViewController inside Switch

Question

Hi I have here a code from didSelectRowAtIndexPath, and my problem is i cannot use switch case by calling a UIViewController

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[tableView deselectRowAtIndexPath:indexPath animated:YES];

TaskList *account = nil;
if (indexPath.section == 0) {
    account = [_forCheckerList objectAtIndex:indexPath.row];
}else if (indexPath.section == 1) {
    account = [_forApprovalList objectAtIndex:indexPath.row];
}else{
    account = [_forVerificationList objectAtIndex:indexPath.row];
}

NSDictionary *funcColors = (NSDictionary*)[dict objectForKey:@"funcTags"];
int tag = [[funcColors objectForKey:[account funcCd]] intValue];
FundTransferOwnViewController *sc = [[FundTransferOwnViewController alloc]init];
[self.navigationController pushViewController:sc animated:YES];
switch (tag) {
    case 10: //aca
        AutoCreditViewController *sc = [[AutoCreditViewController alloc]init];
        [self.navigationController pushViewController:sc animated:YES];
        break;
    default:
        break;
}}

On case 10, i am calling AutoCreditViewController, it always prompts with a red exclamation point saying "Expected Expression".

im not still able to post an image here in stack overflow. :( — lhencq, Feb 19 '14 at 06:36

Embed the switch case within braces { } like

switch (tag) 
{
   case 10: 
   {
      AutoCreditViewController *sc = [[AutoCreditViewController alloc]init];
      [self.navigationController pushViewController:sc animated:YES];
      break;
    }
   default:
      break;
 }

When initialising a new object within a switch you need to add curly braces {. So your switch should look like this:

switch (tag) {
    case 10:
        {
            AutoCreditViewController *sc = [[AutoCreditViewController alloc]init];
            [self.navigationController pushViewController:sc animated:YES];
            break;
        }
    default:
        break;
}}
