title: AVCaptureSession record audio from bluetooth microphone
body: <p>From searching today I think it is still not possible to use a Bluetooth headset microphone as the audio input for an AVCaptureSession (video recording) on an iOS device even with the audio changes made in iOS7. However in case I just haven't looked hard enough has anyone found a way to achieve this?</p>
  
  <p>According to the apple docs kAudioSessionProperty_OverrideCategoryEnableBluetoothInput can be set for the kAudioSessionCategory_RecordAudio or kAudioSessionCategory_PlayAndRecord categories. However the AudioSessionSetProperty method required to do this has been depreciated.  Ignoring that and just using it I still can't find a way to utilize this to get the bluetooth audio passed to a video recording.</p>
