IOS 7 issues BAD_ACCESS when using UIImagePickerController

Question

I am trying to use UIImagePickerController to allow my users to select photos or take photos to be used in my application. But the application seems to crash most often when the image is selected from their photos or when they prefer to use the photo. I used NSZombie objects and I got this message:

[NSISRestrictedToNonNegativeVariable save]: message sent to freed instance 0x168c3530

I do not know what is going on here. The same problem arose when I sometimes presented a modal view.

Here is my code to represent the UIImagePickerController and handle the response:

- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
    {
        if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:CANCEL_TITLE]) {
            return;
        }
        UIImagePickerControllerSourceType sourceType = buttonIndex == 0 ? UIImagePickerControllerSourceTypePhotoLibrary : UIImagePickerControllerSourceTypeCamera;
        UIImagePickerController* controller = [[UIImagePickerController alloc] init];
        controller.sourceType = sourceType;
        [controller setDelegate:self];
        if (buttonIndex == 1) {
            //PNCoverOverlayView* overlayView = [PNCoverOverlayView viewWithNibNamed:nil];
            //[controller setCameraOverlayView:overlayView];
            [controller setShowsCameraControls:YES];
        }
        [self presentViewController:controller animated:YES completion:nil];
    }

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
    {
        [picker dismissViewControllerAnimated:YES completion:^{
            UIImage* originalImage = info[UIImagePickerControllerOriginalImage];
            _imageToUpload = originalImage;
            CGFloat scaleAdjust = ([[UIScreen mainScreen] respondsToSelector:@selector(scale)] && [[UIScreen mainScreen] scale] == 2) ? 0.5 : 1;
            CGFloat length = LENGTH * scaleAdjust;
            if ([picker sourceType] == UIImagePickerControllerSourceTypeCamera) {
                PNCoverOverlayView* overlay = (PNCoverOverlayView*)[picker cameraOverlayView];
                CGSize overlaySize = [overlay frame].size;
                UIImage* cropped = [UIImage imageCroppedToSize:overlaySize fromImage:originalImage];
                _imageToUpload =[UIImage imageResizedToSize:CGSizeMake(length, length) fromImage:cropped];
            } else {
                _imageToUpload = [UIImage imageScaledToMaximumLength:length fromImage:originalImage];
            }
            [self performSegueWithIdentifier:@"reviewPhotoUpload" sender:self];
        }];
    }
