使用预缓冲开始在iOS中播放SoundCloud音频流

使用SoundCloud Developers页面中的以下代码示例,AVAudioPlayer将在收到SCrequest响应后开始播放.根据所请求文件的大小,这可能需要一些时间.iOS SoundCloud API是否提供预缓冲解决方案,以便可以在收到所有数据之前开始播放音频,或者我是否需要实现在NSURLConnection的帮助下自己的解决方案,以实现这一目标？

- (void)tableView:(UITableView *)tableView didSELEctRowATindexPath:(NSIndexPath *)indexPath
{
     NSDictionary *track = [self.tracks objectATindex:indexPath.row];
     NSString *streamURL = [track objectForKey:@"stream_url"];
     SCAccount *account = [SCSoundCloud account];

     [SCrequest performMethod:SCrequestMethodGET
                   onresource:[NSURL URLWithString:streamURL]
              usingParameters:nil
                  withAccount:account
       sendingProgressHandler:nil
              responseHandler:^(NSURLResponse *response,NSData *data,NSError *error) {
             NSError *playerError;
             player = [[AVAudioPlayer alloc] initWithData:data error:&playerError];
             [player prepareToPlay];
             [player play];
         }];
}

NSString *urlString = [NSString StringWithFormat:@"%@?client_id=%@",track.streamURL,self.clientId];
player = [[AVPlayer alloc] initWithURL:[NSURL URLWithString:urlString]];
[player play];
