我已经为流媒体音频编写了一个Titanium iOS模块。 在iPhone 5s及以上的应用程序和模块运行良好。
问题是每次在iPhone 5或我的应用程序中调用stopStream函数时，应用程序崩溃。
我认为存在内存泄漏或其他问题，但我找不到解决该问题的方法。
这是我的模块代码：
//这个功能开始了流。 IPHONE 5上没有问题
-(id)startStream:(id)args
{
ENSURE_SINGLE_ARG(args,NSString);
NSURL *url = [NSURL URLWithString:args];
playerItem = [AVPlayerItem playerItemWithURL:url];
[playerItem addObserver:self forKeyPath:@"timedMetadata" options:NSKeyValueObservingOptionNew context:nil];
player = [[AVPlayer playerWithPlayerItem:playerItem] retain];
[player addObserver:self forKeyPath:@"status" options:0 context:nil];
[player play];
[self fireEvent:@"START" withObject:nil];
NSLog(@"[INFO] player item error : %@", playerItem.error.description);
NSLog(@"[INFO] player error : %@", player.error.description);
return args;
}
//这是我的应用程序在IPHONE 5上崩溃的功能
-(id)stopStream:(id)args
{
NSLog(@"[INFO]AVPlayer STOP");
[player pause];
[playerItem removeObserver:self forKeyPath:@"timedMetadata" context:nil];
[player removeObserver:self forKeyPath:@"status" context:nil];
player=nil;
}
这是设备日志的一部分。

我找到了解决问题的方法。 我必须在函数中添加一个返回值。 现在它适用于iPhone5及更低版本
-(id)stopStream:(id)args
{
NSLog(@"[INFO]AVPlayer STOP");
[player pause];
[playerItem removeObserver:self forKeyPath:@"timedMetadata" context:nil];
[player removeObserver:self forKeyPath:@"status" context:nil];
return args;
}

你也过度保留了这名球员。您应[player release];或stopStream中的startStream仅在实例化新player时才会显示。{/ p>
