How to block incoming phone calls, text messages and email in Objective C

Question

Is there any way to block incoming phone calls, text messages and email. Will appstore allows these kind of applications on appstore. Please help me if this is possible or not.

Answer 1

It is now possible from iOS 10 to block the unwanted calls

Checkout the CallKit framework

CallKit introduces app extensions that enable call blocking and caller identification. You can create an app extension that can associate a phone number with a name or tell the system when a number should be blocked.
