我正在调用OrderDetailsVIEwController – 当我尝试在此处保存上下文时发生错误：

- (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];}

}
`

然后在OrdersDetailVIEwController中我的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]]; }

谁能指出我正确的方向？我可以看到,由于某种原因,我的上下文认为它属于它的父母,但我不确定.拉出我的头发！

解决方法 我遇到了同样的问题,经过艰苦无用的调试后,我在这里发现了一个有效的解决方案： http://tinymission.com/blog/blogengine.web/post/2011/03/04/NSFetchedResultsController-and-EXC_BAD_ACCESS.aspx

引用：

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;}

无论如何,我写了一篇评论,要求提供苹果文档的网址(因为我在没有找到小费的情况下读了很多时间！)

PS.在我的代码中我添加了对[super vIEwWilldisappear：animated]的调用; ：P
