ios - AVPlayer 在状态达到 "ReadyToPlay"后仍有延迟

Question

我想从我的服务器播放 mp3 文件，我执行以下操作:

NSURL *url = [NSURL URLWithString:item.audioUrl];

AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];

self.player = [AVPlayer playerWithPlayerItem:playerItem];

self.player addObserver:self forKeyPath:@"status" options:0 context:nil];

self.hud = [[MBProgressHUD alloc]initWithFrame:CGRectMake(150, 5, 50, 50)];     
self.hud.mode = MBProgressHUDModeIndeterminate;
[self.hud show:YES];
[self.containerView addSubview:self.hud];

这是我的 observeValueForKeyPath:

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {

if (object == self.player && [keyPath isEqualToString:@"status"])
{
    if (self.player.status == AVPlayerStatusReadyToPlay)
    {
        [self.hud hide:YES];
        [self.player play];
.
.
.

现在的问题是，即使 AVPlayer 的状态已更改为“readyToPlay”，它仍然需要大约 2-3 秒才能开始播放，当然我的加载 Spinner 在音乐开始之前会被隐藏....任何想法？

尝试使用方法 [self.player addObserver:self forKeyPath:@"status"options:0 context:nil]; by [self.playerItem addObserver:self forKeyPath:@"状态”选项:0 上下文:无]
