How to delete row and subrow

[RajChanchal]

I uncommented the two methods related to row deletion:
-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { return YES; }
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

But how can I differentiate whether it is subRow to delete or not? And what is the way to call the right indexPath on tableView to delete a row?

[tblView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
