类别中运行一个音频会话，并为录音机选择了playAndRecord选项。我们称之为mixWithOthers。
recordAudioSession我还有另一个在let recordAudioSession = AudioSession()
recordAudioSession.setCategory(.playAndRecord, options: [.mixWithOthers])
类别中运行的音频会话，并且有playback选项用于播放音频流。我们称之为mixWithOthers。
playAudioSession我有一个音频正在使用AVAudioPlayer通过我的let playAudioSession= AudioSession()
playAudioSession.setCategory(.playback, options: [.mixWithOthers])
播放，同时有一个录音机正在我的playAudioSession中运行，试图记录音频。
现在，一旦音频播放完毕，我会尝试停用recordAudioSession，但让playAudioSession保持活动状态：
recordAudioSession因此，基本上，一个会话完成了任务，我想停用它，另一个会话仍在使用中，所以我想保持它的正常运行。
但是我收到错误日志，并且记录仪被系统关闭：
audioPlayer.stop()
playAudioSession.setActive(false, options: .notifyOthersOnDeactivation)
此错误是否意味着在停用音频会话时任何音频会话都无法运行I / O，或者我使用的方式不正确？
有什么方法可以使记录器保持读取状态并停用AVAudioSession.mm:692: -[AVAudioSession setActive:withOptions:error:]: Deactivating an audio session that has running i/o. all i/o should be stopped or paused prior to deactivating the audio session.
