私のアプリでは、AVAudioPlayerを使用してオーディオを再生します。それはすべて大丈夫で、数分間は正常に動作しますが、ある時点でクラッシュし、これが私のコードとコンソール出力ですが、問題を解決する方法がわかりません...

私はこのコードを持っています：

- (void) viewDidLoad{
    [super viewDidLoad];

    soundID = [[AVAudioPlayer alloc]init];
}

- (void)playAudioReturnLettera{
    NSString *path = [NSString stringWithFormat:@"%@/%@",
                      [[NSBundle mainBundle] resourcePath],
                      @"returnObject.mp3"];
    NSURL *filePath = [NSURL fileURLWithPath:path isDirectory:NO];
    [soundID initWithContentsOfURL:filePath error:nil];
    soundID.delegate = self; //<-- here I have the problem (Thread 1)
    [soundID prepareToPlay]; 
    [soundID play];

}

これはコンソールの出力です：

メソッドが返すオブジェクトを保存せずinitWithContentsOfURL:error:に、すでに初期化されたオブジェクト（ ）に対して初期化メソッド（）を呼び出しています。soundID

割り当てと初期化を一緒に維持する（そして一度だけ初期化する）ことをお勧めします。そうすれば、コードは次のようになります。

- (void) viewDidLoad{

    [super viewDidLoad];

    NSString *path = [NSString stringWithFormat:@"%@/%@",
                     [[NSBundle mainBundle] resourcePath],
                     @"returnObject.mp3"];
    NSURL *filePath = [NSURL fileURLWithPath:path isDirectory:NO];
    soundID = [[AVAudioPlayer alloc] initWithContentsOfURL:filePath error:nil];
    soundID.delegate = self;
}

- (void)playAudioReturnLettera{
    [soundID prepareToPlay]; 
    [soundID play];
}

このコードを試してください。これはあなたのために働くでしょう。AVAudioPlayerDelegate.hファイルに追加することを忘れないでください。

- (void) viewDidLoad{

    [super viewDidLoad];

}

- (void)playAudioReturnLettera{
    NSString *path = [NSString stringWithFormat:@"%@/%@",
                     [[NSBundle mainBundle] resourcePath],
                     @"returnObject.mp3"];
    NSURL *filePath = [NSURL fileURLWithPath:path];
    soundID = [[AVAudioPlayer alloc] initWithContentsOfURL:filePath error:nil];
    soundID.delegate = self;
    [soundID play];
}
-(void)audioPlayerDidFinishPlaying: (AVAudioPlayer *)player successfully:(BOOL)flag{
    NSLog(@"Audio Player Successfully played");
}

-(void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error{

    NSLog(@"Decode Error occurred");
}
