NSFetchedResultsControllerDelegate methods not being called when camera image saved in didFinishPickingMediaWithInfo using Core Data

Question

My application allows a user to take an image with the camera or select an image from their photo library.

Inside didFinishPickingMediaWithInfo I get the image and save it to the database using Core Data.

When I get an image from the photo library I see the following NSFetchedResultsControllerDelegate methods being called:

– controllerWillChangeContent: – controller:didChangeObject:atIndexPath:forChangeType:newIndexPath: – controllerDidChangeContent:

When I get an image using the camera I do not see the above methods being called.

Below is my code:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    UIImage* selectedImage = [info objectForKey:UIImagePickerControllerOriginalImage];

    // Create an image object for the new image.
    NSManagedObject *image = [NSEntityDescription insertNewObjectForEntityForName:@"Image" inManagedObjectContext:managedObjectContext];

    // Set the image for the image managed object.
    [image setValue:[selectedImage scaleAndCropImageToScreenSize] forKey:@"image"];


    // Create a thumbnail version of the image.
    UIImage *imageThumbnail = [selectedImage thumbnailImage:50.0F];

    // Create a new note
    Note *note = [NSEntityDescription insertNewObjectForEntityForName:@"Note" inManagedObjectContext:managedObjectContext];
    NSDate *now = [[NSDate alloc] init];
    note.createdDate = now;
    note.lastModifiedDate = now;
    [now release];
    note.thumbnail = imageThumbnail;
    note.image = image;
    [self dismissModalViewControllerAnimated:YES];
    [picker release];

}

               break;

        } else {

        }
