I would like to integrate the iPhone call functionality with my sample application. I have researched and found a way to integrate the call functionality with my application from Stack Overflow question Make a call from my iPhone application.
Also, in Stack Overflow question How to access iPhone contact details in my sample application?, I have found a way to show available contacts in my application from the below link using the AddressBook API.
However, I didn't find any coding to integrate "Decline, busy, answer, text message, text message reply, etc." functionality with my sample application.
How could I accomplish this?
