Question

So I have an application that have a tab in tab bar that display my TableView. Recently I modified it, and change my path for table from default
NSString *path = [[NSBundle mainBundle]pathForResource:@"Food" ofType"plist"];

replacing it with this:
NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject]stringByAppendingString:@"food.plist"];

So my problem is, it work pretty fine when I am launching it on Simulator in XCode, but, when im trying to launch it on my iphone I cant see any TableView appear, just empty search bar and top navigation bar.

- (void)viewDidLoad {
    [super viewDidLoad];

    NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject]stringByAppendingString:@"food.plist"];
    listOfItems = [[NSMutableArray alloc]initWithContentsOfFile:path];
    searchListOfItems = [[NSMutableArray alloc]init];

    searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 45)];
    searchBar.barStyle = UIBarStyleBlackTranslucent;
    searchBar.showsCancelButton = NO;
    searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
    searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
    searchBar.delegate = self; 
    [[self tableView] setTableHeaderView:searchBar];

    searching = NO;
    letUserSelectRow = YES;
    UIBarButtonItem *addButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addProduct:)];
    self.navigationItem.rightBarButtonItem = addButton;

    [self.tableView reloadData]; 
}

- (void)hideModalViewController:(NSNotification *)notif {
    [self dismissModalViewControllerAnimated:YES];
    [self viewDidLoad];
}
- (void)addProduct:(UIBarButtonItem *)button {
    BIDAddProductViewController *addProductVC = [[BIDAddProductViewController alloc]init];
    [self presentModalViewController:addProductVC animated:YES];
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(hideModalViewController:) name:@"HideModalViewController" object:addProductVC];
}
- (void)viewDidUnload {
    [super viewDidUnload];
    self.childController = nil;
    self.tableView = nil;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        NSLog(@"Delete");
        NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject]stringByAppendingString:@"food.plist"];
        NSMutableArray *listOfItemsToDelete = [[NSMutableArray alloc]initWithContentsOfFile:path];

        [[[listOfItemsToDelete objectAtIndex:indexPath.section]objectForKey:@"Products"] removeObjectAtIndex:indexPath.row];
        [listOfItemsToDelete writeToFile:path atomically:YES];
        [self viewDidLoad];
    }
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
    return UITableViewCellEditingStyleDelete;
}

- (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SectionsTableIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:SectionsTableIdentifier];
    }

    if(searching)
        cell.textLabel.text = [[searchListOfItems objectAtIndex:indexPath.row]valueForKey:@"ProductName"];
    else {
        NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section];
         NSArray *array = [[dictionary objectForKey:@"Products"]valueForKeyPath:@"ProductName"];
        NSString *cellValue = [array objectAtIndex:indexPath.row];
        cell.textLabel.text = cellValue;
    }
    cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
    return cell;
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    if (searching)
        return 1;
    else
        return [listOfItems count];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    if (searching)
        return [searchListOfItems count];
    else {
        NSDictionary *dictionary = [listOfItems objectAtIndex:section];
        NSArray *array = [dictionary objectForKey:@"Products"];
        return [array count];
    }
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
    if(searching)
        return @"";
   return [[listOfItems objectAtIndex:section]valueForKey:@"SectionName"];
}

@end

I want to mention that I did some things with Project and Target settings, but, before that issue everything was just fine. I have an iPhone 4s if thats matter. And I did cut lot of my code rows just for make it easier to read (removed searching methods and selecting row methods).

Please help me!

I think the problem is with –

NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject]stringByAppendingString:@"food.plist"];

you need to use –

NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject]stringByAppendingPathComponent:@"food.plist"];
