NSCoreData：委托未为特定实体保存的方法

Question

我有以下三种方法供您查看：

https://gist.github.com/emilevictor/6e01e9c30ce38e9e8a3f

第一种方法＆＃34; actionsheet：clickedButtonAtIndex：＆＃34;创建TreatmentLaser，TreatmentPASI或TreatmentSurgery。保存这些实体时，始终会调用委托（方法3）。这一切都是顺利完成的。

第二种方法＆＃34; onClickNewConsultation：＆＃34;，做同样的事情 - 这次有两个实体，Consult和ClinicalExam。它们彼此相关。第一次加载VC并通过按钮调用此方法时，将调用委托方法。然而，每次从那时起，事实并非如此。有谁知道为什么会出现这种情况？

编辑：

此处添加了代码，以防删除要点：

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSInteger adjustedIndex = 0;

    if (!_laserEnabled) {
        adjustedIndex++;
        if (!_pasiEnabled)
            adjustedIndex++;
    }
    else if (!_pasiEnabled && buttonIndex > 0) {
        adjustedIndex++;
    }

    //    if (!_laserEnabled && adjustedIndex > 2)
    //        adjustedIndex++;
    //    }

    switch (buttonIndex + adjustedIndex) {
        case 0:
        {
            TreatmentLaser *newTreatment = [NSEntityDescription insertNewObjectForEntityForName:@"TreatmentLaser" inManagedObjectContext:SCDataManager.app.managedObjectContext];
            newTreatment.date = [NSDate date];
            newTreatment.patient = _patient;

            NSError *error = nil;
            // Save the object to persistent store
            if (![SCDataManager.app.managedObjectContext save:&error]) {
                NSLog(@"Can't Save! %@ %@", error, [error localizedDescription]);
                return;
            }

            break;
        }

        case 1:
        {
            TreatmentPASI *newTreatment = [NSEntityDescription insertNewObjectForEntityForName:@"TreatmentPASI" inManagedObjectContext:SCDataManager.app.managedObjectContext];
            newTreatment.date = [NSDate date];
            newTreatment.patient = _patient;

            NSError *error = nil;
            // Save the object to persistent store
            if (![SCDataManager.app.managedObjectContext save:&error]) {
                NSLog(@"Can't Save! %@ %@", error, [error localizedDescription]);
                return;
            }

            break;
        }

        case 2:
        {
            TreatmentSurgery *newTreatment = [NSEntityDescription insertNewObjectForEntityForName:@"TreatmentSurgery" inManagedObjectContext:SCDataManager.app.managedObjectContext];
            newTreatment.date = [NSDate date];
            newTreatment.patient = _patient;


            SurgerySites *surgerySite = [NSEntityDescription insertNewObjectForEntityForName:@"SurgerySites" inManagedObjectContext:SCDataManager.app.managedObjectContext];
            surgerySite.treatmentSurgery = newTreatment;


            NSError *error = nil;
            // Save the object to persistent store
            if (![SCDataManager.app.managedObjectContext save:&error]) {
                NSLog(@"Can't Save! %@ %@", error, [error localizedDescription]);
                return;
            }

            break;
        }

        default:
            break;
    }
}

方法2：

- (IBAction)onClickNewConsultation:(UIButton *)sender {

    Consult *newConsult = [NSEntityDescription insertNewObjectForEntityForName:@"Consult" inManagedObjectContext:SCDataManager.app.managedObjectContext];
    newConsult.date = [NSDate date];
    newConsult.patient = _patient;

    ClinicalExam *clinicalExam = [NSEntityDescription insertNewObjectForEntityForName:@"ClinicalExam" inManagedObjectContext:SCDataManager.app.managedObjectContext];
    clinicalExam.consult = newConsult;


    NSError *error = nil;
    // Save the object to persistent store
    if (![SCDataManager.app.managedObjectContext save:&error]) {
        NSLog(@"Can't Save! %@ %@", error, [error localizedDescription]);
        return;
    }

    //    [self update];


}

委托方法（3）：

#pragma mark - NSFetchedResultsControllerDelegate

- (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath
{

    if (_consultsFRC == controller) {
        if (type == NSFetchedResultsChangeInsert) {

            [_consultTable insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:newIndexPath.row inSection:0]] withRowAnimation:UITableViewRowAnimationAutomatic];

            [_consultTable selectRowAtIndexPath:[NSIndexPath indexPathForRow:newIndexPath.row inSection:0] animated:YES scrollPosition:UITableViewScrollPositionMiddle];

            [self performSegueWithIdentifier:@"toConsult" sender:self];
        }
        else if (type == NSFetchedResultsChangeDelete) {

            //[_consultTable deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexPath.row inSection:0]] withRowAnimation:UITableViewRowAnimationAutomatic];
        }

    }
    else if (_treatmentLasersFRC == controller) {
        if (type == NSFetchedResultsChangeInsert) {

            [_consultTable insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:newIndexPath.row inSection:1]] withRowAnimation:UITableViewRowAnimationAutomatic];

            [_consultTable selectRowAtIndexPath:[NSIndexPath indexPathForRow:newIndexPath.row inSection:1] animated:YES scrollPosition:UITableViewScrollPositionMiddle];

            [self performSegueWithIdentifier:@"toTreatmentLaser" sender:self];
        }
        else if (type == NSFetchedResultsChangeDelete) {

            //[_consultTable deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexPath.row inSection:1]] withRowAnimation:UITableViewRowAnimationAutomatic];
        }
    }
    else if (_treatmentPASIsFRC == controller) {
        if (type == NSFetchedResultsChangeInsert) {

            [_consultTable insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:newIndexPath.row inSection:2]] withRowAnimation:UITableViewRowAnimationAutomatic];

            [_consultTable selectRowAtIndexPath:[NSIndexPath indexPathForRow:newIndexPath.row inSection:2] animated:YES scrollPosition:UITableViewScrollPositionMiddle];

            [self performSegueWithIdentifier:@"toTreatmentPASI" sender:self];
        }
        else if (type == NSFetchedResultsChangeDelete) {

            //[_consultTable deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexPath.row inSection:2]] withRowAnimation:UITableViewRowAnimationAutomatic];
        }
    }
    else if (_treatmentProFormasFRC == controller) {
        if (type == NSFetchedResultsChangeInsert) {

            [_consultTable insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:newIndexPath.row inSection:3]] withRowAnimation:UITableViewRowAnimationAutomatic];

            [_consultTable selectRowAtIndexPath:[NSIndexPath indexPathForRow:newIndexPath.row inSection:3] animated:YES scrollPosition:UITableViewScrollPositionMiddle];

            [self performSegueWithIdentifier:@"toTreatmentProForma" sender:self];
        }
        else if (type == NSFetchedResultsChangeDelete) {

            [_consultTable deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexPath.row inSection:3]] withRowAnimation:UITableViewRowAnimationAutomatic];
        }
    }

    //    [self performSegueWithIdentifier:@"toTreatmentLaser" sender:self];
