Xcode AVPlayer崩潰iPhone 5 - 鈦iOS模塊

我已經寫了流媒體音頻的鈦iOS模塊。在iPhone 5s及以上的應用程序和模塊運行良好。Xcode AVPlayer崩潰iPhone 5 - 鈦iOS模塊

問題是每當我的應用程序在iPhone 5中調用stopStream函數或降低應用程序崩潰時。

我認爲有內存泄漏或者其他東西，但我沒有找到解決這個問題。

這裏是我的模塊代碼：

//這個函數THET開始流。是沒有問題的ON THE IPHONE 5

-(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; 
}

//這是函數WHERE MY APP CRASH ON IPHONE 5

-(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; 
}

這裏該裝置日誌的一個組成部分。

當您發佈關於崩潰的問題時，您必須提供有關崩潰的詳細信息。什麼是完整的和確切的錯誤信息，以及哪條線正在導致崩潰？ – rmaddy

這是我的大問題。在每個模擬器中，應用程序運行都沒有問題。只有在真正的iPhone 5設備上，應用程序崩潰。目前，我不能在真正的iPhone 5上測試它，我可以連接到我的Mac。我只能讓其他人測試應用程序時，我建立它或測試它在這裏testobject.com。這就是爲什麼我沒有日誌或錯誤消息 – tablesuplex

您可以從測試用戶獲得崩潰報告。他們需要使用iTunes將他們的設備同步到他們的電腦。然後，崩潰報告將在他們的電腦上。 – rmaddy

我找到了我的問題的解決方案。我必須在函數中添加一個返回值。現在它適用於iPhone5和更低版本

-(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; 
}

你也超過了保留球員。您應該在您的stopStream或startStream中[player release];，如果尚不存在，只實例化新的player。
