Programmatically answer an incoming phone call on iPhone

Question

如何在iPhone上使用Objective-C以编程方式接听来电？

Answer 1

You can't. You don't even got a notification or whatever that there's an incoming call. All you can do is ask the iPhone to make a call (via the tel: URI scheme) but you won't even know whether the phone actually did dial the number.

That is on purpose for privacy/anti-malware reasons, BTW.
