AVFAudio - 在 AVAudioRecorder.stop() 之后立即执行文件复制是否安全

Question

我们通过

开始录音

self.avAudioRecorder = try AVAudioRecorder(
    url: self.recordingFileUrl, 
    settings: settings
)
self.avAudioRecorder.record()

在某些时候，我们会通过

停止录制

self.avAudioRecorder.stop()

我想知道，在 self.avAudioRecorder.stop() 之后立即对 self.recordingFileUrl 执行文件复制是否安全？

是否所有记录数据都已刷新到self.recordingFileUrl并且self.recordingFileUrl文件已正确关闭？

Answer 1

在audioRecorderDidFinishRecording(_:successfully:)

中执行文件保存似乎更安全

It does seem to be synchronous, though in theory something could still fail at that point, so it is safer to use the delegate method audioRecorderDidFinishRecording(_:successfully:), rather than make an assumption that the recording will always succeed after calling stop.
