iOS流音频和录制音频

Question

我有一个应用程序，当我按下按钮时应该录制音频。 在我的ViewDidLoad中我预先录制了录音机，问题是当调用'self.audioRecorder.prepareToRecord（）'行时，流式音频会中断。

我的设置：

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)
}

有没有办法预录音录音机进行录音，并继续在后台播放音频？ （录制音频时将其丢弃）

Per Apple's documentation for AVAudio​Session​Category​​Record，＆＃34;此类别使播放音频静音＆＃34;。您是否尝试将类别设置为AVAudio​Session​Category​Play​And​Record？
