There's two ways you can get pictures on iOS.
1. UIImagePickerController - This opens the system image picker and ONLY returns the user selected image to the application.
2. "Access Camera Roll" Permission - This is what WhatsApp, Facebook, etc. use so that they can show their own image picker UI. It just gives the app permanent access to APIs that can retrieve photos.
Both leak EXIF information to the app, but the first one only leaks the information for a specific picture.
