d'abord l'arrière-plan:accident CoreData sur mergeChangesFromContextDidSaveNotification: invalide Résumé
J'ai un singleton qui fait tout mon CoreData choses liées à ce sujet. Il est appelé à partir de plusieurs threads. Pour chaque thread, je génère un nouveau MOC en utilisant toujours le même StoreCoordinator. J'ai deux fetchedResultsController qui doivent être mis à jour dès que les données changent sur un autre thread. Pour fusionner les modifications, j'appelle addControllerContextDidSave: comme dans l'application de démonstration de livres.
- (void)addControllerContextDidSave:(NSNotification*)saveNotification {
if (saveNotification) {
NSManagedObjectContext *fahrzeugeContext = [fetchedFahrzeuge managedObjectContext];
NSManagedObjectContext *accountContext = [fetchedAccount managedObjectContext];
// Merging changes causes the fetched results controller to update its results
@try {
if (fahrzeugeContext) [fahrzeugeContext mergeChangesFromContextDidSaveNotification:saveNotification];
if (accountContext) [accountContext mergeChangesFromContextDidSaveNotification:saveNotification];
}
@catch (NSException * e) {NSLog(@"Merge Notification Error: %@", e);}
}
}
Dans certains cas très rares, l'application se bloque avec une EXC_BAD_ACCESS en ligne mergeChangesFromContextDidSaveNotification: disant que le saveNotification a un invalid Summary. (Même le bloc try-catch ne fonctionne pas)
Cela n'arrive que sur des situations vraiment très rares (par exemple une fois par semaine) donc je ne peux pas le tester correctement.
Ce qui peut causer cela et plus important comment le réparer. Maintenant, je suis en train de tester avec if (saveNotification) {} mais encore une fois, il peut prendre un certain temps jusqu'à ce qu'il se reproduise.

Le problème commun de simultanéité ici est que vous appelez mergeChangesFromContextDidSaveNotification: à partir d'un thread différent de celui sur lequel vous avez créé le contexte cible. par exemple. vous créez un contexte sur le thread principal, mais appelez mergeChanges à partir d'un thread différent. Assurez-vous que tous vos appels à mergeChanges se trouvent sur le thread propriétaire du contexte, vous pouvez utiliser performSelector: OnThread: pour cela. – ImHuntingWabbits
Je suis sûr que c'est sur le même thread car j'appelle la sauvegarde du même contexte et puis fusionne les changements d'un autre contexte. BTW J'ai inclus un journal de panne. –
