Question

AVAudioPlayer成功调用了播放方法，并且在模拟器中正常工作，但它没有播放声音。该设备具有iOS 7.1.1。这是我用过的代码。

NSBundle *mainBundle = [NSBundle mainBundle];
         NSString *filePath = [mainBundle pathForResource:@"miata-hn" ofType:@"wav"];
        NSData *fileData = [NSData dataWithContentsOfFile:filePath];
        NSError *error = nil;
        /* Start the audio player */
        self.playerAudio = [[AVAudioPlayer alloc] initWithData:fileData error:&error];
        self.playerAudio.volume = 1;

        if (error)
        {
            NSLog(@"error localized description %@",[error localizedDescription]);
        }

        if (self.playerAudio != nil)
        {
            /* Set the delegate and start playing */
            self.playerAudio.delegate = self;

            if ([self.playerAudio prepareToPlay] && [self.playerAudio play])
            {
                NSLog(@"player success");
            }
            else
            {
                NSLog(@"sound player failed to play audio");
            }
        }
        else
        {
                /* Failed to instantiate AVAudioPlayer */
        }

我得到了解决方案。添加此行代码后，可在应用程序中听到音频。 AVAudioSession应该被激活。

**

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&error];
    [[AVAudioSession sharedInstance] setActive:YES error:&error];

**

尝试使用：

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath];
AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];

AVAudioPlayer成功调用播放方法但不播放声音
