ios – 录制时实时上传音频剪辑？

录音时如何将音频素材实时上传到服务器？基本上我的要求是录制时将卡片/数据包上传到音频剪辑.
我已经使用IQAudioRecorderController https://github.com/hackiftekhar/IQAudioRecorderController做了录音部分.它记录音频并保存到TemporaryDirectory.

我想知道如何上传实时而不保存音频剪辑.

这是录音部分

//Unique recording URL


NSString *filename = [[NSProcessInfo processInfo] globallyUniqueString];
_recordingFilePath = [NstemporaryDirectory() StringByAppendingPathComponent:[NSString StringWithFormat:@"%@.m4a",filename]];


// Initiate and prepare the recorder

_audioRecorder = [[AVAudioRecorder alloc] initWithURL:[NSURL fileURLWithPath:_recordingFilePath] setTings:recordSetTing error:nil];
_audioRecorder.delegate = self;
_audioRecorder.meteringEnabled = YES;


// Recording start
- (void)recordingButtonAction:(UIBarButtonItem *)item
{
 if (_isRecording == NO)
  {
    _isRecording = YES;

    //UI update
    {
        [self showNavigationButton:NO];
        _recordButton.TintColor = _recordingTintColor;
        _playButton.enabled = NO;
        _trashButton.enabled = NO;
    }

    /*
     Create the recorder
     */
    if ([[NSFileManager defaultManager] fileExistsAtPath:_recordingFilePath])
    {
        [[NSFileManager defaultManager] removeItemAtPath:_recordingFilePath error:nil];
    }

    _oldSessionCategory = [[AVAudioSession sharedInstance] category];
    [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryRecord error:nil];
    [_audioRecorder prepareToRecord];
    [_audioRecorder record];
}
else
{
    _isRecording = NO;

    //UI update
    {
        [self showNavigationButton:YES];
        _recordButton.TintColor = _normalTintColor;
        _playButton.enabled = YES;
        _trashButton.enabled = YES;
    }

    [_audioRecorder stop];
    [[AVAudioSession sharedInstance] setCategory:_oldSessionCategory error:nil];
}
}  

// Recording done

-(void)doneAction:(UIBarButtonItem*)item
{
  if ([self.delegate respondsToSELEctor:@SELEctor(audioRecorderController:didFinishWithAudioAtPath:)])
  {
      IQAudioRecorderController *controller = (IQAudioRecorderController*)[self navigationController];
      [self.delegate audioRecorderController:controller didFinishWithAudioAtPath:_recordingFilePath];
  }

  [self dismissviewControllerAnimated:YES completion:nil];
}
