I'm developing an iOS voip app using Callkit and Linphone. When I receive a incoming call, system shows the native phone UI to user accept or decline de call, whe the user taps accept button the call starts but de phone UI dissapear.
How can I keep native phone UI after user accept the call, like whatsapp do?
Also, how can I show the native phone UI when start a outgoing call?
Here's my providerDelegate code:
func reportIncomingCall(uuid: UUID, handle: String, hasVideo: Bool = false, completion: ((NSError?) -> Void)? = nil) {
// Construct a CXCallUpdate describing the incoming call, including the caller.
let update = CXCallUpdate()
update.remoteHandle = CXHandle(type: .generic, value: handle)
update.hasVideo = hasVideo
// Report the incoming call to the system
provider.reportNewIncomingCall(with: uuid, update: update) { error in
/*
Only add incoming call to the app's list of calls if the call was allowed (i.e. there was no error)
since calls may be "denied" for various legitimate reasons. See CXErrorCodeIncomingCallError.
*/
if error == nil {
print("calling")
}
}
}
func provider(_ provider: CXProvider, perform action: CXStartCallAction) {
let update = CXCallUpdate()
update.remoteHandle = action.handle
provider.reportOutgoingCall(with: action.uuid, startedConnectingAt: Date())
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "callStart"), object: self, userInfo: ["uuid":action.uuid])
action.fulfill(withDateStarted: Date())
}
func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "callStart"), object: self, userInfo: ["uuid":action.uuid])
// ACCEPT CALL ON SIP MANAGER
if let voiceCallManager = AppDelegate.voiceCallManager {
voiceCallManager.acceptCall()
}
action.fulfill(withDateConnected: Date())
}
