iOS local notifations on new pictures in gallery - ios

I would like to show a badge on my app icon when new pictures are taken on the phone stock camera.
How can I register for this event? If not possible , is there a way to tell when iCloud of the user added new photos and get notify the user to open the application?
If not can I schedule an event to the user (lets say every hour) and run some code to check if pictures were added to the gallery - if so display a badge so the user will open my app?

Detect screenshots taken ON ANY APP within my iOS app

Is it possible to detect when the user takes a screenshot in any app while my app is in the background ? And how would I do that ?
If not, can I background check regularly for screenshots (not pictures from the camera) in the photo library ? Like every minute or hour ?

One way to get your app to detect Screenshots is:
Register with the Photo Library's PHPhotoLibraryChangeObserver
When your app receives a notification that a photo has been added,
check its PHAssetMediaSubtype
If the Subtype is PHAssetMediaSubtypePhotoScreenshot, you know a new
Screenshot has been taken.
The PHPhotoLibraryChangeObserver protocol notifies you of changes that
occur in the Photos library, regardless of whether those changes are
made by your app, by a user in the Photos app, or by another app that
uses the Photos framework.
