通过多对等连接在多台设备中播放歌曲

Question

我想在多设备连接的同时播放歌曲，例如 ampme应用。因此，我使用了this library，但遇到了以下困难。

1。）主持人暂停了歌曲，但所有来宾都没有收到暂停动作

2。）有时语音中断

3。）无法互相连接设备

4。）暂停操作后歌曲无法同步播放

5。）歌曲未在来宾中播放，但表明正在播放中

6。）播放歌曲时设备断开连接

7。）连接设备问题

8。）同样，歌曲会在多于两台设备中播放，然后只会在一台设备中播放。

这是一些代码

  

主机端

 - (void)mediaPicker:(MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection
{
    [self dismissViewControllerAnimated:YES completion:nil];

    if (self.outputStreamer) return;

    self.song = mediaItemCollection.items[0];

    NSMutableDictionary *info = [NSMutableDictionary dictionary];
    info[@"title"] = [self.song valueForProperty:MPMediaItemPropertyTitle] ? [self.song valueForProperty:MPMediaItemPropertyTitle] : @"";
    info[@"artist"] = [self.song valueForProperty:MPMediaItemPropertyArtist] ? [self.song valueForProperty:MPMediaItemPropertyArtist] : @"";

    MPMediaItemArtwork *artwork = [self.song valueForProperty:MPMediaItemPropertyArtwork];
    UIImage *image = [artwork imageWithSize:self.albumImage.frame.size];
    if (image)
        info[@"artwork"] = image;

    if (info[@"artwork"])
        self.albumImage.image = info[@"artwork"];
    else
        self.albumImage.image = nil;

    self.songTitle.text = info[@"title"];
    self.songArtist.text = info[@"artist"];

    [self.session sendData:[NSKeyedArchiver archivedDataWithRootObject:[info copy]]];

    NSArray *peers = [self.session connectedPeers];

    if (peers.count) {
        self.outputStreamer = [[TDAudioOutputStreamer alloc] initWithOutputStream:[self.session outputStreamForPeer:peers[0]]];
        [self.outputStreamer streamAudioFromURL:[self.song valueForProperty:MPMediaItemPropertyAssetURL]];
        [self.outputStreamer start];
    }
}
