I am having a problem with my ipad app.

I’ve got a view that is accessed in 2 ways, if i go in one way it works perfectly. If I go in through another though, it crashes when saving the context.

I suspect it is something in the parent (orders by customer) — I get a zombie with the message:

[OrdersByCustomer controllerWillChangeContent:]: message sent to deallocated instance 0x10102020
when I run it through intstruments with Zombies I get:

I am calling OrderDetailsViewController — where the error occurs when I try to save the context here:

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
 {

NSArray *viewControllers;

if (scOrdersInvoices.selectedSegmentIndex == INVOICES){

    InvoiceDetailsViewController <SubstitutableDetailViewController> *invoiceDetailsViewController = 
    [[InvoiceDetailsViewController alloc] initWithNibName:@"InvoiceDetailsView" bundle:nil];

    invoiceDetailsViewController.invoice = [_fetchedInvoicesResultsController objectAtIndexPath:indexPath];
    invoiceDetailsViewController.tempPopoverButtonItem = self.rootPopoverButtonItem;

    viewControllers = [[NSArray alloc] initWithObjects:
                       [appDelegate.splitViewController.viewControllers objectAtIndex:0],
                       invoiceDetailsViewController,
                       nil];
    appDelegate.splitViewController.viewControllers = viewControllers;

    [invoiceDetailsViewController release];   
    [viewControllers release];
    return;
}

Orders *newOrder = [[_fetchedOrdersResultsController fetchedObjects] objectAtIndex:indexPath.row];
if (newOrder)
{

    OrderDetailsViewController <SubstitutableDetailViewController> *orderDetailsViewController = [[OrderDetailsViewController alloc] initWithNibName:@"OrderDetailsView" bundle:nil];
    orderDetailsViewController.tempPopoverButtonItem = self.rootPopoverButtonItem;
    orderDetailsViewController.orders = newOrder;
    orderDetailsViewController.iCalledFrom = 1;
    NSArray *viewControllers = [[NSArray alloc]initWithObjects:
                                [appDelegate.splitViewController.viewControllers objectAtIndex:0],
                                orderDetailsViewController,
                                nil];
    appDelegate.splitViewController.viewControllers = viewControllers;          
    [orderDetailsViewController release];  
    [viewControllers release];

}

}
`

and then in OrdersDetailViewController my viewDidLoad:

 - (void)viewDidLoad
 {
appDelegate = (D4AppDelegate *)[[UIApplication sharedApplication]delegate];
self.managedObjectContext = appDelegate.managedObjectContext;
HistoryOrCatalogController *hoc = [[HistoryOrCatalogController alloc] initWithNibName:@"HistoryOrCatalogController" bundle:[NSBundle mainBundle]];
hoc.delegate = self;
UIPopoverController *po = [[UIPopoverController alloc]initWithContentViewController:hoc];
po.popoverContentSize = CGSizeMake(200.0, 90.0);
[hoc release];
self.searchPopover = po;
[po release];

[super viewDidLoad];
total = 0.0f;
qtyAddedToOrder = 0;
if (iCalledFrom == 1) {
    UIBarButtonItem *bi = [[[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(back)]autorelease];
    [navigationBar.topItem setLeftBarButtonItem:bi animated:YES];

}
NSError *error;
orderID = orders.OrderID;
if(![[self fetchedResultsController] performFetch:&error]){
    NSLog(@"Order Error: %@, %@", error, [error userInfo]);
}
[self updateInterface];

self.navigationBar.topItem.title = [NSString stringWithFormat:@"Order # %d", [orders.OrderID intValue]];


 }

Can anyone point me in the right direction? I can see that for some reason my context thinks it belongs to its parent, but i’m not sure. Pulling my hair out!

I was facing the same issue and after an hard and useless debug, I found a post here with an effective solution: http://tinymission.com/blog/blogengine.web/post/2011/03/04/NSFetchedResultsController-and-EXC_BAD_ACCESS.aspx

Quote:

Buried deep within the Core Data programming guide the simple solution
was to be sure to always set fetchedResultsController to nil after the
view disappears. I was releasing it in the dealloc function, but that
wasn’t enough — it needs to be set to nil. To make sure that it gets
set to nil right away, I implemented viewWillDisappear: and put the
code in there. Problem solved!

-(void)viewWillDisappear:(BOOL)animated {
 self.fetchedResultsController = nil;
}

anyway I wrote a comment asking for an url to the apple documentation (since I lost hours to read it without finding the tip!!)

ps. in my code I added a call to [super viewWillDisappear:animated]; 😛
