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.

When the user select an image from the gallery, I can use

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


    if([[info valueForKey:@"UIImagePickerControllerMediaType"] isEqualToString:@"public.image"]) {
           NSURL *imageUrl = [info valueForKey:@"UIImagePickerControllerReferenceURL"];

}

}

Instead, if the user takes a photo on the fly, I save it in the photo roll with:

  UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

  UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);

After saving it, I would to retrieve the corresponding NSURL as the user had selected it.

How could I do?

EDIT

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 

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

is called again and I can use the UIImagePickerControllerReferenceURL key to retrieve the corresponding url.

  • @Lachezar Todorov: I had to maintain the compatibility with 3.1 iOS, anyway, I'll consider it for the future. Thank you very much. – Sefran Aug 24 '11 at 19:29

  • do you mean automatically selecting the previous image that was taken and saved – visakh7 May 11 '11 at 10:09
  • @7KV7: Yes. By my app, the user takes the photo. When the user clicks on the "use" button I save it in the photo roll. Then I would to retrieve the corresponding url as the user had selected it from the gallery. – Sefran May 11 '11 at 10:16
