Core Data wont save changes - ios

Question

I'm having a bit of a problem with my code, I'm actually using RestKit to map various objects in core data, that works well, then I need to edit certain object, when I edit it and save the context all works very well and without problem, the trouble is when I stop de application and open it again, none of the changes I've made are saved, here is my code:
[managedObjectStore createPersistentStoreCoordinator];
NSString *storePath = [RKApplicationDataDirectory() stringByAppendingPathComponent:#"TaskModel.sqlite"];
NSString *seedPath = [[NSBundle mainBundle] pathForResource:#"RKSeedDatabase" ofType:#"sqlite"];
NSError *error;
NSPersistentStore *persistentStore = [managedObjectStore addSQLitePersistentStoreAtPath:storePath fromSeedDatabaseAtPath:seedPath withConfiguration:nil options:nil error:&error];
NSAssert(persistentStore, #"Failed to add persistent store with error %#", error);
//create the managed object contexts
[managedObjectStore createManagedObjectContexts];
//Configure a managed object cache to ensure we do not create duplicate objects
managedObjectStore.managedObjectCache = [[RKInMemoryManagedObjectCache alloc] initWithManagedObjectContext:managedObjectStore.persistentStoreManagedObjectContext];
then this is my update method:
// Get data
// 1.- Create the request object:
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSManagedObjectContext *localContext = [RKManagedObjectStore defaultStore].mainQueueManagedObjectContext;
// 3.- Define the type of managed object you need:
NSEntityDescription *entity = [NSEntityDescription entityForName:#"SavedTask" inManagedObjectContext:localContext];
[fetchRequest setEntity:entity];
[fetchRequest setReturnsObjectsAsFaults:NO];
NSPredicate *searchTasktoComplete = [NSPredicate predicateWithFormat:#"taskId == %#", self.task.taskId];
[fetchRequest setPredicate:searchTasktoComplete];
// 5.- Execute the request:
NSError *error;
NSArray *fetchedTasks = [localContext executeFetchRequest:fetchRequest error:&error];
SavedTask *taskToComplete = [fetchedTasks objectAtIndex:0];
//complete the task in core data
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"MM/dd/yyyy"];
NSString *date = [dateFormat stringFromDate:[NSDate date]];
[taskToComplete setRealDate:date];
[taskToComplete setFollowUp:#"100"];
[localContext refreshObject:taskToComplete mergeChanges:YES];
[localContext save:&error];
if (![localContext save:&error]) {
NSLog(#"error");
}
can anyone help me?, thanks in advance

Answer 1

You should use the saveToPersistentStore method
NSError *error = nil;
if(![localContext saveToPersistentStore:&error]){
NSLog(#"Failed to save to data store");
}

Answer 2

Try this!
NSError *error = nil;
NSManagedObjectContext *managedObjectContext = self.managedObjectContext;
if (managedObjectContext != nil) {
if ([managedObjectContext hasChanges] && ![managedObjectContext save:&error]) {
// Replace this implementation with code to handle the error appropriately.
// abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
NSLog(#"Unresolved error %#, %#", error, [error userInfo]);
abort();
}
}
