UIImagePickerController Shutter Detection

Question

Is there a way to detect when the camera has finished taking a picture?

Currently I'm using the below method:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    [picker dismissViewControllerAnimated:YES completion:nil];
    NSLog(@"END");
    _showAlert = NO;
    _alertIsShowing = NO;
    if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
        UIImageWriteToSavedPhotosAlbum([info objectForKey:@"UIImagePickerControllerOriginalImage"], nil, nil, nil);
        _endAlerts = YES;
    }
    _imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    _saveBtn.hidden = NO;
}

That triggers after the user has clicked the "Use Photo" button. I want something that triggers as soon as the image is captured in the image picker view.

It seems the only way of doing this is to create my own overlay, which in and of itself is proving to be a pain the rear end.
