iOS Requirement (A10.16) Ensure that when iTunes Radio is playing, Game Music must be set to “Off” automatically

Hey there @ChimeraSW, here is a simple plugin we used to accomplish what you want:

Save it as DetectMusicPlayer.mm or something similar, and place it in your Plugins/iOS folder.

 #import <MediaPlayer/MediaPlayer.h>
 
 extern "C" {
 
     bool _DetectMusicPlayer() {
         
         bool playerDetectedAndPlaying = false;
         NSString *reqSysVer = @"3.0";
         NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
         if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending){
             Class MusicPlayerController = NSClassFromString(@"MPMusicPlayerController");
             if (MusicPlayerController){         
                 id myMusicPlayerController = [[MusicPlayerController alloc]init];
                 id MusicPlayer = [[myMusicPlayerController class] iPodMusicPlayer ];
                 if ( [ MusicPlayer playbackState ] == MPMusicPlaybackStatePlaying ) {
                     playerDetectedAndPlaying = true;
                 }
             }
         }
 
         return playerDetectedAndPlaying;
     }
     
     void _ResumeMusicPlayer()
     {
         
         NSString *reqSysVer = @"3.0";
         NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
         if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending){
             Class MusicPlayerController = NSClassFromString(@"MPMusicPlayerController");
             if (MusicPlayerController){
                 id myMusicPlayerController = [[MusicPlayerController alloc]init];
                 id MusicPlayer = [[myMusicPlayerController class] iPodMusicPlayer ];
                 if ( [ MusicPlayer playbackState ] != MPMusicPlaybackStatePlaying ) {
                     [myMusicPlayerController play];
                 }
             }
         }
     }
     
 }
 

Then, in another script, say DetectMusicPlayer.cs, give a callback to the native plugin like so:

 using UnityEngine;
 using System.Collections;
 using System.Runtime.InteropServices;
 
 public class DetectMusicPlayer
 {
     #if UNITY_IOS
     [DllImport("__Internal")]
     static private extern bool _DetectMusicPlayer();
     [DllImport("__Internal")]
     static private extern void _ResumeMusicPlayer();
     #endif
 
     static public bool Detect()
     {
         #if UNITY_IOS
         return _DetectMusicPlayer();
         #else
             return false;
         #endif
     }
 
     static public void ResumePlayer()
     {
         #if UNITY_IOS
         Debug.Log("Resuming music player");
         _ResumeMusicPlayer();
         #endif
     }
 }
 
 //Usage example
 /*
 //Some global Listener class...
 
 void OnApplicationFocus(bool isFocused)
 {
     bool musicPlaying = DetectMusicPlayer.Detect();
 
     if (musicPlaying)
     {
         // Mute game music here...
     }
     else
     {
         //Unmute game music here...
     }
 }
 
 */
 

Hope this helps!
