AVPlayer连接丢失重启

我正在使用 AVPlayer 对象在我的 iOS 应用程序中播放远程广播流。该流工作正常并在后台播放。

进行一些连接测试时我遇到了一些问题。一旦播放器连接丢失，播放器就会停止（如您所料），但是当连接恢复时我无法使播放器再次开始。

我粗略地设置了一个计时器，每秒点击 [player play] 来强制它启动，但没有运气。我最好的猜测是基于缺乏所请求的数据，它刚刚死了。

我确实有一个观察者设置来监视玩家何时准备好开始或者是否出现错误，但似乎在初始时间之后根本没有被调用。

我的问题是如何强制 AVPlayer 在可用时再次开始获取流。

我已将音频播放器子类化为 BCRadio

-(BCRadio*)initWithRadioOneAndAutoPlay:(BOOL)autoPlay whenReady:(void(^)(void))ready whenFailed:(void(^)(void))failed whenBecameActive:(void(^)(void))active {

    // Current item
    self.playerItem = [[AVPlayerItem alloc] initWithURL:[NSURL URLWithString:@"http://69.64.92.79:8276"]];

    // Super it
    self = [super initWithPlayerItem:self.playerItem];

    // Observe for it become ready
    [self addObserver:self forKeyPath:@"status" options:0 context:nil];

    // If app comes from background and if app goes inactive
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appBecameActive) name:UIApplicationDidBecomeActiveNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appEnteredBackground) name:UIApplicationDidEnterBackgroundNotification object:nil];

    // Set blocks
    self.playerReady = ready;
    self.playerFailed = failed;
    self.playerActive = active;
    self.willAutoPlay = autoPlay;

    // Register for remote notifications
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

    // Play is pressed
    [[NSNotificationCenter defaultCenter] addObserverForName:@"TogglePlay" object:nil queue:NULL usingBlock:^(NSNotification *notification){
        [self doPlay:YES];
    }];

    // Pause is pressed
    [[NSNotificationCenter defaultCenter] addObserverForName:@"TogglePause" object:nil queue:NULL usingBlock:^(NSNotification *notification){
        [self doPlay:NO];
    }];


    // Check if playing
    NSTimer *timer = [NSTimer bk_scheduledTimerWithTimeInterval:1 block:^(NSTimer *timer){
        [self statusMonitor];
    } repeats:YES];
    [timer fire];

    // Monitor reachability and pause when needed
    Reachability* reach = [Reachability reachabilityWithHostname:@"69.64.92.79"];
    reach.reachableBlock = ^(Reachability*reach){
        if(self.willAutoPlayOnResume && !self.playing){
            self.willAutoPlayOnResume = NO;
            [self doPlay:YES];
        }
    };
    reach.unreachableBlock = ^(Reachability*reach){
        if(self.playing){
            self.willAutoPlayOnResume = YES;
            [self doPlay:NO];
        }
    };
    [reach startNotifier];

    return self;

}
