title: Retrieve the url of an image taken on the fly and saved in the gallery, how?
body: <p>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 so that I can use it to display the image in a second moment.</p>
  
  <p>When the user select an image from the gallery, I can use</p>
  
  <pre><code>- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
  
  
      if([[info valueForKey:@"UIImagePickerControllerMediaType"] isEqualToString:@"public.image"]) {
             NSURL *imageUrl = [info valueForKey:@"UIImagePickerControllerReferenceURL"];
  
  }
  </code></pre>
  
  <p>}</p>
  
  <p>Instead, if the user takes a photo on the fly, I save it in the photo roll with:</p>
  
  <pre><code>  UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
  
    UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
  </code></pre>
  
  <p>After saving it, I would to retrieve the corresponding NSURL as the user had selected it.</p>
  
  <p>How could I do?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>My problem isn't about the image chosen from the gallery. I succeed in retrieving the url using the UIImagePickerControllerReferenceURL path. My problem is when the user takes a photo with the camera. I can write it in the photo roll, but I should find a way to automatically select it such that </p>
  
  <pre><code>- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
  </code></pre>
  
  <p>is called again and I can use the UIImagePickerControllerReferenceURL key to retrieve the corresponding url.</p>
