implementation of Agora signalling to communicate

问题:

I am currently working on Agora.io services which give us

audio,video,one-to-one and broadcast communication

I have successfully implemented these with the help of there given samples, and successfully add signalling module. Problem is that signalling call must be active to access all features of it now I want to access all features of signalling at the time when app is closed like whatsapp and other these type of application one solution is make a service of signalling class but this is not professional solution.

I want efficient one solution

回答1:

This cannot be done with any 3rd party APIs. This is a system level functionality offered by Apple & Google. You will have to use CallKit (for iOS) or ConnectionService (for Android) to achieve this functionality.

I have done exactly the same thing a few days ago.

For iOS, you have use PushKit and CallKit in the following ways:-

.1. Enable background mode and also check voip.

2. Import Pushkit and implement PKPushRegistryDelegate functions.

Register pushkit like this :-

  func registerPushkitToken() -> Void {
        pushRegistry = PKPushRegistry.init(queue: DispatchQueue.main)
        pushRegistry?.delegate = self
        pushRegistry?.desiredPushTypes = [.voIP]
    }

3.Implement the token fuction

func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: 
     PKPushCredentials, for type: PKPushType) {

let tokenChars = pushCredentials.token.hexString()
 }

4. Implement the following function for parsing notification

   func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) { if let userInfo = payload.dictionaryPayload["userInfo"] as? [AnyHashable:Any]{ } }

5. Implement provider delegate functions:

   let providerConfiguration = CXProviderConfiguration(localizedName: appName) providerConfiguration.supportsVideo = true providerConfiguration.maximumCallsPerCallGroup = 1 providerConfiguration.maximumCallGroups = 1 providerConfiguration.supportedHandleTypes = [.generic]

Implement CXProviderDelegate functions

func providerDidReset(_ provider: CXProvider) {
        print("Function: \(#function), line: \(#line)")

        sessionPool.removeAll()
    }

    func provider(_ provider: CXProvider, perform action: CXStartCallAction) {

        print("Function: \(#function), line: \(#line)")

        guard let session = pairedSession(of:action.callUUID) else {
            action.fail()
            return
        }

        let callUpdate = CXCallUpdate()
        callUpdate.remoteHandle = action.handle
        callUpdate.hasVideo = true
        callUpdate.localizedCallerName = callDetails.dispalyName;
        callUpdate.supportsDTMF = false
        provider.reportCall(with: action.callUUID, updated: callUpdate)

        delegate?.callCenter(self, startCall: session)
        action.fulfill()
    }
