How to play next song Automatically when using AudioStreamer?

---

In the tutorial is mentioned callback function which is triggered when a song finish playing. Your goal is to write functionality for your list of songs to move on the next one when this function is called.

void MyAudioQueueIsRunningCallback( void *                  inClientData,
                         AudioSessionPropertyID inID,
                         UInt32                  inDataSize,
                         const void *            inData)
{
move to the next song
}

I got answer,

In that tutorial there isplaybackStateChanged:(NSNotification *)aNotification method,

    - (void)playbackStateChanged:(NSNotification *)aNotification
    {
    if ([songStreamer isWaiting])
   {

   }
       if ([songStreamer isPlaying])
   {

   }
   else if ([songStreamer isIdle])
   {
         [self playnextsong];

   }

      else if ([songStreamer isPaused])
  {

  }
}

When song completes through streaming, It going to idle state. So in idle state i call a method of playing next song.

And it Runs.
