You want to use CGImageSourceRef rather than UIImage, see the CGImageSourceRef documentation. You then use code like
NSDictionary* metadata = (NSDictionary *)CGImageSourceCopyPropertiesAtIndex(source,0,NULL);
to get the meta data. There is a detailed tutorial here.

I found that in this delegate method - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info there is all what I need. Thanks for your answer btw. :) – GhzNcl Aug 02 '12 at 19:14
