Developing an app for an iPhone with audio files that need to be listened too through headphones.

How do I check if headphones aren&#39;t plugged in so I can tell the user to plug in headphones.

I have the following code from another thread but the audioSessionGetProperty method is deprecated. Anyone know how to alter the following code to make this work OR have there own code/solution. 

Thanks.

    - (BOOL)isHeadsetPluggedIn {
        UInt32 routeSize = sizeof (CFStringRef);
        CFStringRef route;


        //Maybe changing it to something like the following would work for iOS7?
        //AVAudioSession* session = [AVAudioSession sharedInstance];
        //OSStatus error = [session setCategory:kAudioSessionProperty_AudioRoute...?
        
    
        //the line below is whats giving me the warning
        OSStatus error = AudioSessionGetProperty (kAudioSessionProperty_AudioRoute,
                                                  &amp;routeSize,
                                                  &amp;route);
        
        /* Known values of route:
         * &quot;Headset&quot;
         * &quot;Headphone&quot;
         * &quot;Speaker&quot;
         * &quot;SpeakerAndMicrophone&quot;
         * &quot;HeadphonesAndMicrophone&quot;
         * &quot;HeadsetInOut&quot;
         * &quot;ReceiverAndMicrophone&quot;
         * &quot;Lineout&quot;
         */
        
        if (!error &amp;&amp; (route != NULL)) {
            
            NSString* routeStr = (__bridge NSString*)route;
            
            NSRange headphoneRange = [routeStr rangeOfString : @&quot;Head&quot;];
            
            if (headphoneRange.location != NSNotFound) return YES;
            
        }
        
        return NO;
    }
