我知道有关于AVAudioSession的类似问题,但我的有点不同。 我遇到了AVAudioSession中断的问题。
拒绝通话后,它会恢复,但只保存中断后记录的部分 - 部分在通话之前只是消失。
对于已接听的电话,即使1秒钟也能正常工作 - 它会恢复并保存整个录音。
差异我注意到当我接听电话时,.began和.ended都会被调用两次,但是当我拒绝一个电话时,它只会调用一次。
开始录制:
func startRecording(name:String, quality:AudioQuality, progress:@escaping RecorderProgress, completed:@escaping RecorderCompletion, microphoneProgress:@escaping MicrophoneProgress) {
log("Recorder - About to start recording")
if isAudioRecordingGranted {
self.device = EZMicrophone(microphoneDelegate: self, startsImmediately: true)
self.name = name
//Create the session.
self.recorderProgress = progress
self.recorderCompletion = completed
self.microphoneProgress = microphoneProgress
let session = AVAudioSession.sharedInstance()
NotificationCenter.default.addObserver(self, selector: #selector(handleInterruption(notification:)), name: NSNotification.Name.AVAudioSessionInterruption, object: session)
do {
try session.setCategory(AVAudioSessionCategoryPlayAndRecord, with: .defaultToSpeaker)
try session.setActive(true)
let settings = [
AVFormatIDKey: Int(kAudioFormatMPEG4AAC),
AVSampleRateKey: 44100,
AVNumberOfChannelsKey: 2,
AVEncoderAudioQualityKey: audioQuality.rawValue
]
let audioFilename = Directory.documents.appendingPathComponent("\(self.name).m4a")
audioRecorder = try AVAudioRecorder(url: audioFilename, settings: settings)
audioRecorder.delegate = self
audioRecorder.isMeteringEnabled = true
audioRecorder.record()
isRecording = true
log("Recorder - Started recording, file at path: \(audioFilename.absoluteString)")
meterTimer = Timer.scheduledTimer(timeInterval: 0.1, target:self, selector:#selector(update), userInfo:nil, repeats:true)
}
catch let error {
completed(error, 0, 0)
log("Recorder - Error occured while starting audio recording: \(error.localizedDescription)")
}
}
}
通知处理程序:
@objc func handleInterruption(notification: Notification) {
guard let userInfo = notification.userInfo,
let interruptionTypeRawValue = userInfo[AVAudioSessionInterruptionTypeKey] as? UInt,
let interruptionType = AVAudioSessionInterruptionType(rawValue: interruptionTypeRawValue),
let session = notification.object as? AVAudioSession else {
log("Recorder - something went wrong")
return
}
switch interruptionType {
case .began:
log("Recorder - interruption began")
try! session.setActive(false)
audioRecorder.pause()
case .ended:
try! session.setActive(true)
log("Recorder - interruption ended")
}
}
答案 0 :(得分:0)
所以我设法暂停录制,然后直接从AVAudioSession暂停,使用CallKit和CXCallObserver委托函数func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall)
,这是在来电时调用的。
