如何在Objective-C中从字节数组创建音频？

Question

在Android中，我使用下面的代码行生成的字节数组

byte audioData[]; 
//. 
//fill audioData 
//. 
final AudioTrack audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, 
      sampleRateInHz, AudioFormat.CHANNEL_CONFIGURATION_MONO, 
      AudioFormat.ENCODING_PCM_16BIT, audioData.lenght, 
      AudioTrack.MODE_STATIC); 
audioTrack.write(audioData, 0, audioData.length); 
audioTrack.play(); 

声音我怎么能在IOS SDK实现这一目标。是否有任何等效库从byteArray生成声音？

你可以尝试：

NSData *audioData = // take audioData from wherever it is 

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

self.audioPlayer = [[AVAudioPlayer alloc] initWithData:audioData error:nil]; // audioPlayer must be a strong property. Do not create it locally 

[self.audioPlayer prepareToPlay]; 
[self.audioPlayer play]; 

确保导入AVFoundation模块
