Xcode Not Using NSMutableArray on Table Cells

I am building an iPhone application that is using a table cell. I set up this code to try to delete cells from the table, but it does not seem to work because I am not using a NSMutableArray. When I swipe I get the delete button but the delete button does not do anything. My question is if I am not using NSMutableArray with my table cell ho can this line: [self.dataArray removeObjectAtIndex:indexPath.row]; work?

Code Used

(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES; }
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        //remove the deleted object from your data source.
        //If your data source is an NSMutableArray, do this
        [self.dataArray removeObjectAtIndex:indexPath.row];
    } }

Here is the link to the apple doc's on table view programming guide. Table view programming guide It has a easy delegate method that uses NSArray and has an example code you can use for deleting and inserting. The code you have shown above is missing the delegate part in order to perform the delete. Take a look at listing 7.3 that maybe what your looking for.
