Simple curiosity - Code Data Recipe sample

[DevSdk]

In the Core Data Recipe sample, where are the categories list (Snack, Appetizer, etc) actually stored?

This is the code in the TypeSelectionViewController, where it gets the recipeTypes array, which is then used to populate the tableview:

    [super viewWillAppear:animated];
    
	// Fetch the recipe types in alphabetical order by name from the recipe's context.
	NSManagedObjectContext *context = [recipe managedObjectContext];
	
	NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
	[fetchRequest setEntity:[NSEntityDescription entityForName:@"RecipeType" inManagedObjectContext:context]];
	NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES];
	NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:&sortDescriptor count:1];
	[fetchRequest setSortDescriptors:sortDescriptors];
	
	NSError *error = nil;
	NSArray *types = [context executeFetchRequest:fetchRequest error:&error];
	self.recipeTypes = types;
	
	[fetchRequest release];
	[sortDescriptor release];
	[sortDescriptors release];

But where I can change them?

Hey, I'm learning this demo and got the same question, any help?
Thanks a lot!

Well this is old. Anyway, If you look at the app delegate, you'll find this code:

/*
	 Set up the store.
	 For the sake of illustration, provide a pre-populated default store.
	 */
	NSFileManager *fileManager = [NSFileManager defaultManager];
	// If the expected store doesn't exist, copy the default store.
	if (![fileManager fileExistsAtPath:storePath]) {
		NSString *defaultStorePath = [[NSBundle mainBundle] pathForResource:@"Recipes" ofType:@"sqlite"];
		if (defaultStorePath) {
			[fileManager copyItemAtPath:defaultStorePath toPath:storePath error:NULL];
		}
	}

So, it's actually loading the sqlite file to prepopulate the store if there's no data.

This array is readonly. Is there a way to change this list of items.
