iOS流音頻和記錄音頻

Question

我有一個應用程序，它應該記錄音頻時，我按下了一個按鈕。 在我的ViewDidLoad我preapare錄音機，問題是流'音頻中斷時，'self.audioRecorder.prepareToRecord（）'行被調用。

我的設置：

do { 
    recordingSession = AVAudioSession.sharedInstance() 
    try recordingSession.setCategory(AVAudioSessionCategoryRecord, withOptions: [.DuckOthers, .AllowBluetooth, .MixWithOthers]) 

    recordingSession.requestRecordPermission() { [unowned self] (allowed: Bool) -> Void in 
     dispatch_async(dispatch_get_main_queue()) { 
      do { 
       if allowed { 
        self.audioRecorder = try AVAudioRecorder(URL: self.tempAudioPath, settings: self.settings) 
        self.audioRecorder.delegate = self 
        self.audioRecorder.prepareToRecord() 
        //self.audioRecorder.record() 
       } else { 
        // failed to record! 
        print("No Access to Micro") 
       } 
      }catch{} 
     } 
    } 
} catch { 
    print (error) 
} 

是有辦法preapare備案錄音機，並繼續在後臺播放音頻？ （在錄製音頻時將其放在其上）

每Apple's documentation for AVAudio​Session​Category​​Record，「此類別使播放音頻靜音」。您是否嘗試將類別設置爲AVAudio​Session​Category​Play​And​Record？
