【问题标题】：Can't play audio from an online link, using Amazing Audio Engine无法使用惊人的音频引擎播放来自在线链接的音频

【问题描述】：

我正在尝试使用此代码在惊人的音频引擎的帮助下实现在线流式传输/缓冲，但它引发了以下错误：

AEAudioFilePlayer.m:148: AudioFileOpenURL: 'wht?' (2003334207)

代码如下：

 - (void)viewDidLoad {
        [super viewDidLoad];

        self.audioController = [[AEAudioController alloc] initWithAudioDescription:[AEAudioController nonInterleaved16BitStereoAudioDescription] inputEnabled:YES];
    _audioController.preferredBufferDuration = 0.005;
    [_audioController start:NULL];

    [self initWithAudioController:self.audioController];

    AEAudioFilePlayer *oneshot = [AEAudioFilePlayer audioFilePlayerWithURL:[NSURL URLWithString:self.urlOfSong] error:NULL];

    _oneshot.removeUponFinish = YES;
    [_audioController addChannels:[NSArray arrayWithObject:oneshot]];


    }

    - (id)initWithAudioController:(AEAudioController*)audioController {

        self.audioController = audioController;
        NSError *error = NULL;
        BOOL result = [self.audioController start:&error];
        if ( !result ) {
            // Report error
            NSLog(@"The Amazing Audio Engine didn't start!");
        } else {
            NSLog(@"The Amazing Audio Engine started perfectly!");
        }

        return self;
    }

它在 iOS 9 上吗？你有那个done 吗？
yes 允许任意加载，并且在 iOS 9 上确实有效

【解决方案1】：

在.h文件中

@property (nonatomic, strong) AEAudioFilePlayer *player;
@property (nonatomic, strong) AEAudioController *audioController;

在 .m 文件中

-(void)playAudio
{

    self.audioController = [[AEAudioController alloc] initWithAudioDescription:[AEAudioController nonInterleaved16BitStereoAudioDescription] inputEnabled:YES];
    _audioController.preferredBufferDuration = 0.005;
    [_audioController start:NULL];

    [self initWithAudioController:self.audioController];

    if ( _player ) {
        [_audioController removeChannels:@[_player]];
        self.player = nil;
    } else {
        NSArray *documentsFolders = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *path = [documentsFolders[0] stringByAppendingPathComponent:kFileName];
        if ( ![[NSFileManager defaultManager] fileExistsAtPath:path] ) return;

        NSError *error = nil;
        self.player = [AEAudioFilePlayer audioFilePlayerWithURL:[NSURL fileURLWithPath:path] error:&error];

        if ( !_player ) {
            [[[UIAlertView alloc] initWithTitle:@"Error"
                                        message:[NSString stringWithFormat:@"Couldn't start playback: %@", [error localizedDescription]]
                                       delegate:nil
                              cancelButtonTitle:nil
                              otherButtonTitles:@"OK", nil] show];
            return;
        }
         [self startTimer];
        _player.removeUponFinish = YES;

        _player.completionBlock = ^{
            _audioController = nil;
            [ _audioController removeChannels:@[_player]];
            [self remveTimer];
            self.player = nil;

        };
        [_audioController addChannels:@[_player]];

    }

}




- (id)initWithAudioController:(AEAudioController*)audioController {

    self.audioController = audioController;
    NSError *error = NULL;
    BOOL result = [self.audioController start:&error];
    if ( !result ) {
        // Report error
        NSLog(@"The Amazing Audio Engine didn't start!");
    } else {
        NSLog(@"The Amazing Audio Engine started perfectly!");
    }



    return self;
}
