请注意，我分享了我的代码及其即将满足我的需求，我分享以供参考。您需要根据需要进行更改。
当您收到 voip 通知时，创建您的 webrtc 处理类的新事件，并且
将这两行添加到代码块中，因为从 voip 通知启用音频会话失败
RTCAudioSession.sharedInstance().useManualAudio = true
RTCAudioSession.sharedInstance().isAudioEnabled = false
didReceive 方法；
func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void) {
let state = UIApplication.shared.applicationState
if(payload.dictionaryPayload["hangup"] == nil && state != .active
){
Globals.voipPayload = payload.dictionaryPayload as! [String:Any] // I pass parameters to Webrtc handler via Global singleton to create answer according to sdp sent by payload.
RTCAudioSession.sharedInstance().useManualAudio = true
RTCAudioSession.sharedInstance().isAudioEnabled = false
Globals.sipGateway = SipGateway() // my Webrtc and Janus gateway handler class
Globals.sipGateway?.configureCredentials(true) // I check janus gateway credentials stored in Shared preferences and initiate websocket connection and create peerconnection
to my janus gateway which is signaling server for my environment
initProvider() //Crating callkit provider
self.update.remoteHandle = CXHandle(type: .generic, value:String(describing: payload.dictionaryPayload["caller_id"]!))
Globals.callId = UUID()
let state = UIApplication.shared.applicationState
Globals.provider.reportNewIncomingCall(with:Globals.callId , update: self.update, completion: { error in
})
}
}
func initProvider(){
let config = CXProviderConfiguration(localizedName: "ulakBEL")
config.iconTemplateImageData = UIImage(named: "ulakbel")!.pngData()
config.ringtoneSound = "ringtone.caf"
// config.includesCallsInRecents = false;
config.supportsVideo = false
Globals.provider = CXProvider(configuration:config )
Globals.provider.setDelegate(self, queue: nil)
update = CXCallUpdate()
update.hasVideo = false
update.supportsDTMF = true
}
修改您的 didActivate 和 didDeActive 委托函数，如下所示，
func provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession) {
print("CallManager didActivate")
RTCAudioSession.sharedInstance().audioSessionDidActivate(audioSession)
RTCAudioSession.sharedInstance().isAudioEnabled = true
// self.callDelegate?.callIsAnswered()
}
func provider(_ provider: CXProvider, didDeactivate audioSession: AVAudioSession) {
print("CallManager didDeactivate")
RTCAudioSession.sharedInstance().audioSessionDidDeactivate(audioSession)
RTCAudioSession.sharedInstance().isAudioEnabled = false
}
在 Webrtc 处理程序类中配置媒体发送者和音频会话
private func createPeerConnection(webRTCCallbacks:PluginHandleWebRTCCallbacksDelegate) {
let rtcConfig = RTCConfiguration.init()
rtcConfig.iceServers = server.iceServers
rtcConfig.bundlePolicy = RTCBundlePolicy.maxBundle
rtcConfig.rtcpMuxPolicy = RTCRtcpMuxPolicy.require
rtcConfig.continualGatheringPolicy = .gatherContinually
rtcConfig.sdpSemantics = .planB
let constraints = RTCMediaConstraints(mandatoryConstraints: nil,
optionalConstraints: ["DtlsSrtpKeyAgreement":kRTCMediaConstraintsValueTrue])
pc = sessionFactory.peerConnection(with: rtcConfig, constraints: constraints, delegate: nil)
self.createMediaSenders()
self.configureAudioSession()
if webRTCCallbacks.getJsep() != nil{
handleRemoteJsep(webrtcCallbacks: webRTCCallbacks)
}
}
媒体发件人；
private func createMediaSenders() {
let streamId = "stream"
// Audio
let audioTrack = self.createAudioTrack()
self.pc.add(audioTrack, streamIds: [streamId])
// Video
/* let videoTrack = self.createVideoTrack()
self.localVideoTrack = videoTrack
self.peerConnection.add(videoTrack, streamIds: [streamId])
self.remoteVideoTrack = self.peerConnection.transceivers.first { $0.mediaType == .video }?.receiver.track as? RTCVideoTrack
// Data
if let dataChannel = createDataChannel() {
dataChannel.delegate = self
self.localDataChannel = dataChannel
}*/
}
private func createAudioTrack() -> RTCAudioTrack {
let audioConstrains = RTCMediaConstraints(mandatoryConstraints: nil, optionalConstraints: nil)
let audioSource = sessionFactory.audioSource(with: audioConstrains)
let audioTrack = sessionFactory.audioTrack(with: audioSource, trackId: "audio0")
return audioTrack
}
音频会话;
private func configureAudioSession() {
self.rtcAudioSession.lockForConfiguration()
do {
try self.rtcAudioSession.setCategory(AVAudioSession.Category.playAndRecord.rawValue)
try self.rtcAudioSession.setMode(AVAudioSession.Mode.voiceChat.rawValue)
} catch let error {
debugPrint("Error changeing AVAudioSession category: \(error)")
}
self.rtcAudioSession.unlockForConfiguration()
}
请考虑一下，因为我使用回调和委托代码包括委托和回调块。你可以相应地忽略它们！
