[英]Agora cannot record call with iOS Swift
我在这里关注文档:https://docs.agora.io/en/Voice/rtc_recording_apple?platform=iOS并实现基本录音。 这是我的代码:
func startRecording(){
let filename = getDocumentsDirectory().appendingPathComponent("\(APP_NAME)\(now()).WAV")
let str = String(describing: filename)
self.recordingPath = str
agoraKit?.startAudioRecording(str, quality: .high)
}
func stopRecording(){
agoraKit?.stopAudioRecording()
// get audio file
guard let audioUrl = URL(string: self.recordingPath) as? URL else { return }
DispatchQueue.main.asyncAfter(deadline: .now() + 2.0 ) { [weak self] in
// getdata
do {
let myData = try Data(contentsOf: audioUrl)
print(myData.count, myData)
} catch {
print(error)
}
}
}
private func getDocumentsDirectory() -> URL {
let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
return paths[0]
}
但我收到错误消息: The file “Whisper1608949569.WAV” couldn't be opened because there is no such file
完整信息:
file:///var/mobile/Containers/Data/Application/1F682ABD-153C-4DFD-BFF4-
02C1CE6F9A4C/Documents/Whisper1608949569.WAV
Error Domain=NSCocoaErrorDomain Code=260 "The file “Whisper1608949569.WAV” couldn’t be opened because there is no such file."

我没有正确访问文件吗?
这就是我初始化 agora 客户端的方式:
self.agoraKit = AgoraRtcEngineKit.sharedEngine(withAppId: AppID, delegate: self)
agoraKit?.delegate = self
agoraKit?.enableWebSdkInteroperability(true)
// sample loudest speaker every second
agoraKit?.enableAudioVolumeIndication(1000, smooth: 3, report_vad: true)
agoraKit?.enableAudio()
// config for livecast to start
agoraKit?.setChannelProfile(.liveBroadcasting)
// set framrate and HD/SD
agoraKit?.setVideoEncoderConfiguration( CONFIG_PRODUCTION )
//agoraKit?.setDefaultAudioRouteToSpeakerphone(true)
我刚刚查看了您正在使用的文档中引用的文档,它说方法startAudioRecording(filepath, quality: quality) is now deprecated,您应该将此方法与附加的 sampleRate 参数一起使用:
还要检查startAudioRecording和stopAudioRecording的返回值是否返回0,表示成功。
如果您的频道名称包含特殊字符(冒号、斜杠),录制将无声地失败并且不会生成任何文件。 Agora 在创建临时文件时似乎使用了频道名称。
