Save the order of the rearranged cells in a table view - uitableview

Question

I have an application which can rearrange the order of the UITableViewCells and can delete the cells However, I needa way to save the order of the rearranged and deleted table view cells. I am using an nsmutablearray
- (void)viewDidLoad
{
[super viewDidLoad];
if (!maTheData) {
maTheData = [[NSMutableArray alloc] initWithObjects:#"Bus", #"Truck", #"Car",nil];
}
}
- (NSInteger)numberOfSectionsInTableView: (UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [maTheData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"tvcItems"];
UILabel *lblName = (UILabel *)[cell viewWithTag:100];
[lblName setText:[maTheData objectAtIndex: [indexPath row]]];
return cell;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle: (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Delete the row from the data source
[maTheData removeObjectAtIndex:[indexPath row]];
// Delete row using the cool literal version of [NSArray arrayWithObject:indexPath]
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
else if (editingStyle == UITableViewCellEditingStyleInsert) {
// Insert something into the array, and you can just add a populated NSIndexPath of data or simplr reload data
[maTheData addObject:#"I'm a new item!"];
[tableView reloadData];
}
}
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
NSString *mover = [maTheData objectAtIndex: [fromIndexPath row]];
[maTheData removeObjectAtIndex:[fromIndexPath row]];
[maTheData insertObject:mover atIndex:[toIndexPath row]];
[tableView setEditing:NO animated:YES];
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView setEditing:YES animated:YES];
}

To preserve data across application relaunch you have to serialize the content of maTheData into NSData, then write the content of NSData to disk either via NSUserDefaults, or to a file of your own choosing. In the latter case you must also decide in which folder you want to place that file - I would suggest something like the Application Support folder, or at any rate, not the Documents folder.
I know this is not a copy&paste solution, but it should get you started on your further research. Just read the Apple docs and google, there are plenty of resources on the net that explain how to do this in detail.
