Answer 1

First you will have to register for AudioRoute Changes :-

AudioSessionAddPropertyListener (kAudioSessionProperty_AudioRouteChange,
                                     audioRouteChangeListenerCallback,
                                 self);

Here You can depict the reason for changing your route :-

CFDictionaryRef routeChangeDictionary = inPropertyValue;

  CFNumberRef routeChangeReasonRef =
  CFDictionaryGetValue (routeChangeDictionary,
                        CFSTR (kAudioSession_AudioRouteChangeKey_Reason));

  SInt32 routeChangeReason;

      CFNumberGetValue (routeChangeReasonRef, kCFNumberSInt32Type, &routeChangeReason);

  if (routeChangeReason == kAudioSessionRouteChangeReason_OldDeviceUnavailable) 
  {
       // your statements for headset unplugged

  }
  if (routeChangeReason == kAudioSessionRouteChangeReason_NewDeviceAvailable)
  {
       // your statements for headset plugged                             
  }
