 [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord mode:AVAudioSessionModeVideoRecording options:nil error:nil];
 
  AVAudioSessionPortDescription *builtInMicPort = nil;
  for (AVAudioSessionPortDescription *portDescription in audioSession.availableInputs) {
      if ([portDescription.portType isEqualToString:AVAudioSessionPortBuiltInMic]) {
          builtInMicPort = portDescription;
          break;
      }
  }

  if (builtInMicPort) {
      NSError *inputError = nil;
      [audioSession setPreferredInput:builtInMicPort error:&inputError];

      if (inputError) {
          NSLog(@"inputError：%@", inputError);
      }else{
          NSLog(@"change success");
      }
  } else {
      NSLog(@"inputError");
  }
