Воспроизведение непрерывного звука в Iphone

Question

У меня есть этот кусок кода для воспроизведения звука, но как только он закончен, я хочу снова и снова воспроизводить один и тот же звук, я думаю, что я должен использовать numberofloops = -1, но там, где мне нужно используйте это напрямую. Пожалуйста, помогите мне.

Чтобы закодировать песню, используйте ниже код после выделения init avSongItem.

avSongItem.actionAtItemEnd = AVPlayerActionAtItemEndNone; 

Подробнее: Looping a video with AVFoundation AVPlayer?

Кроме того, как указано в уведомлении использования ссылки.

avSongItem.actionAtItemEnd = AVPlayerActionAtItemEndNone;

[[NSNotificationCenter defaultCenter] addObserver:self 
             selector:@selector(playerItemDidReachEnd:) 
              name:AVPlayerItemDidPlayToEndTimeNotification 
             object:[avPlayer currentItem]]; 

Это не позволит игроку остановиться в конце.

в уведомлении:

- (void)playerItemDidReachEnd:(NSNotification *)notification { 
AVPlayerItem *p = [notification object]; 
[p seekToTime:kCMTimeZero]; 
}
