How retrieve the url of an image taken on the fly and saved in the gallery?

[franium]

I allow the user to take a photo on the fly with the camera. When the user clicks on the "use" button, I save the taken image in the photo roll. After saving it, I would to retrieve the corresponding NSURL as the user had selected it.
I should find a way to automatically select it such that

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

is called again and I can use the UIImagePickerControllerReferenceURL key to retrieve the corresponding url.
How could I do?

NSURL *imageUrl = [info valueForKey:@"UIImagePickerControllerReferenceURL"];

works when the user select the image directly from the gallery.

I'm not sure you'll be able to do that other then presenting a new picker. Why do you need it?

Yea, what do you need the url for ?

I allow the user to choose an image from the gallery or take a photo with the camera. I would to save the image path in both cases (I use a sqlite3 database) so that I can use it to display the image in a second moment.

In the first case, I succeed in saving the url using the UIImagePickerControllerReferenceURL key. But how can I do in the second case?

You could just save the camera image to the Documents directory and put that path in your database.

Yes, I know it. But my idea was that the user could find the taken images in the camera roll. And I wouldn't to duplicate the images.
Is there a way to recall the

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

as the user had selected the taken image (when the saving of the taken image is finished)?
