Get the callers phone number from an incoming call on iPhone
<p>I'm trying to get caller ID (phone number) at the time of incoming call.
TrueCaller has implemented this and they get the phone number of incoming caller.</p>

<p>I've found this information:
1. CoreTelephony Framework(It gives only calling states)
2. Apple's 9.0 update : "Maybe" contacts sync. with mail app and detects the incoming phone number.</p>
