iphone - AVPlayer 一直在后台运行

Question

我正在使用 AVPlayer 播放在线电影。它工作正常。现在的问题是，当我在电影开始播放之前从视图中弹出时，后台进程会继续运行。当电影被加载时，它开始在后台播放。

我试图在 viewWillDisappear 中释放播放器。但它不起作用。

- (void)viewWillDisappear:(BOOL)animated
{
    if (self.player.currentItem.status != AVPlayerItemStatusReadyToPlay) 
    {
        [self.player.currentItem removeObserver:self forKeyPath:kRateKey];
        [self.player.currentItem removeObserver:self forKeyPath:kStatusKey];
        [self.player.currentItem removeObserver:self forKeyPath:kTimedMetadataKey];
    }
    [self.player pause];
    [self.player release];
    [self.playerLayerView release];

    [super viewWillDisappear:animated];
}

有人可以帮忙吗？提前致谢

Answer 1

这可能有帮助..

    if (self.player.currentItem.playbackLikelyToKeepUp == 1 ) {

    NSLog(@"Ready To Play");
    [self.player play];


    }else{

    NSLog(@" Show HUD Buffering...");

    [self.player pause];

    }

- (void)viewWillDisappear:(BOOL)animated
        if (self.player.playing==YES) {
            [self.player stop];
            self.player=nil;
        }
    }
