Hello. I am trying to implement background call using agora.
I used pushkit and voip to receiving a call in the background, and getting a call.
But when I accept a call, it's crashing. I am sharing my code and need help.
------------- Sending Part -------------------
appleCallKit.startOutgoingCall(of: targetUserId)
SendVOIPPush(devicetoken, callerName, callerUUID) // sending voip push message so that user can get notification in the background
------------- Receiving Part -----------------
func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void) {
print("###### PushRegistry IncomingPush #########")
let dict = payload.dictionaryPayload
let uuid = dict["uuid"] as! String
let caller_name = dict["caller_name"] as! String
if UIApplication.shared.applicationState == .active {
} else {
showIncomingCall(of: uuid, withUserName: caller_name)
}
}
func showIncomingCall(of session: String, withUserName username: String) {
let callUpdate = CXCallUpdate()
callUpdate.remoteHandle = CXHandle(type: .phoneNumber, value: session)
callUpdate.localizedCallerName = username
callUpdate.hasVideo = true
callUpdate.supportsDTMF = false
let uuid = pairedUUID(of: session)
provider.reportNewIncomingCall(with: uuid, update: callUpdate, completion: { error in
if let error = error {
print("reportNewIncomingCall error: \(error.localizedDescription)")
}
})
}
func callCenter(_ callCenter: CallCenter, answerCall session: String) {
print("callCenter answerCall")
guard let inviter = AgoraRtm.shared().inviter else {
fatalError("rtm inviter nil")
}
guard let channel = inviter.lastIncomingInvitation?.content else {
fatalError("lastIncomingInvitation content nil")
}
guard let remote = UInt(session) else {
fatalError("string to int fail")
}
inviter.accpetLastIncomingInvitation()
// present VideoChat VC after 'callCenterDidActiveAudioSession'
self.prepareToVideoChat = { [weak self] in
var data: (channel: String, remote: UInt)
data.channel = channel
data.remote = remote
self?.navigateVideoCall(data: data)
//self?.performSegue(withIdentifier: "DialToVideoChat", sender: data)
}
}
So when user sends a call, it calls both startOutgooingCall function and an api to send push notification.
And in the receiving part, I called the reportNewIncomingCall in the pushRegistry so that can get incoming call.
So far it's ok.
And when I accept the call, callCenter answrCall delegate is being called. but the inviter.lastIncomingInvitation is nil and it's crashing. I am not able to get channel name because the inviter.lastIncomingInvitation is nil.
I would appreciate if someone could help me.
Thanks.
