MPMusicPlayerController第一次不工作

Question

I have implemented MPMusicPlayerController playing song functionality in the app. Everything working fine but very first time of launching the app is not working.Second time onwards it is working awesome. What I understood is setNowPlayingItem is not setting on first time . Any ideas/suggestions could be very helpful. Thanks for your valuable time.

Code

    MPMediaItemCollection *collection = [[MPMediaItemCollection alloc] initWithItems:[NSArray arrayWithObjects:selectedMediaItem1, nil]];

    [appDelegate.musicPlayer setQueueWithItemCollection:collection];

    [appDelegate.musicPlayer setNowPlayingItem:selectedMediaItem1];

    [appDelegate.musicPlayer prepareToPlay];

    [appDelegate.musicPlayer play];

Answer 1

It's a bug! I opened a Technical Support Incident about this. We hope in iOS 10. Music and apple music will likely have a big update.

Answer 2

you should also set a currentPlaybackTime for your player,

   // Restore the now-playing item and its current playback time.
    appDelegate.musicPlayer.nowPlayingItem      = nowPlayingItem;
    appDelegate.musicPlayer.currentPlaybackTime = currentPlaybackTime;
