Question

所以基本上我想在iOS应用程序中启用Sinch Video。

出于测试目的，我创建了SinchManaevger，它是单例，我在AppDelegate中实现它：

class SinchManager: NSObject, SINClientDelegate, SINCallClientDelegate {

    static let sharedInstance = SinchManager()

    var client: SINClient?

    func initSinchClientWithUserId(id: String) {
        if client == nil {
            if case .Authenticated(let currentUser, _) = SessionManager.sharedInstance.state.value {

                self.client = Sinch.clientWithApplicationKey("xyz", applicationSecret: "xyz", environmentHost: "sandbox.sinch.com", userId: currentUser.username)
                print("sinchClient")
                print(client!)
                self.client!.delegate = self
                self.client!.setSupportCalling(true)
                self.client!.enableManagedPushNotifications()
                self.client!.start()
                self.client!.startListeningOnActiveConnection()

            }
        }
    }

    func clientDidStart(client: SINClient!) {
        print("clientDidStart")
        self.client!.callClient().delegate = self
    }

    func clientDidStop(client: SINClient!) {
        print("clientDidStop")
    }

    func clientDidFail(client: SINClient!, error: NSError!) {
        print("clientDidFail")
    }

    func client(client: SINCallClient!, didReceiveIncomingCall call: SINCall!) {
        print("didReceiveIncomingCall")
        let sinchVC = SinchVC(username: currentUser.username)
        let sinchNC = DNMMainNC(rootViewController: sinchVC)

        sinchVC.call = call
    }
}

我已经创建了Sinch ViewController，它用用户名初始化，将被称为：

class SinchVC: UIViewController, SINCallDelegate {

    private let videoController = SinchManager.sharedInstance.client!.videoController()
    private let audioController = SinchManager.sharedInstance.client!.audioController()
    private let callClient: SINCallClient
    private var call: SINCall!

    let username: String

    private var mainView: SinchView { return view as! SinchView }

    override func loadView() {
        view = SinchView()
    }

    init(username: String) {
        self.username = username
        self.callClient = SinchManager.sharedInstance.client!.callClient()

        super.init(nibName: nil, bundle: nil)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    override func viewDidLoad() {
        super.viewDidLoad()


        call.delegate = self

        self.mainView.videoView.addSubview(self.videoController.localView())
        self.videoController.localView().contentMode = .ScaleToFill

        if self.call.direction == SINCallDirection.Incoming {
            self.audioController.startPlayingSoundFile(self.pathForSound("incoming.wav") as String, loop: true)
        }

        if self.call.details.videoOffered {
            print("video offered")
            self.mainView.videoView.addSubview(self.videoController.localView())
            self.videoController.localView().contentMode = .ScaleToFill
        }

        mainView.videoView.addSubview(self.videoController.localView())
        mainView.answerButton.addTarget(self, action: #selector(answer), forControlEvents: .TouchUpInside)
        mainView.declineButton.addTarget(self, action: #selector(decline), forControlEvents: .TouchUpInside)
    }

    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)
        self.audioController.enableSpeaker()
    }

    func pathForSound(string: String) -> NSString {
        let nsSt = NSBundle.mainBundle().resourcePath! as NSString

        return nsSt.stringByAppendingPathComponent(string)
    }

    func answer() {
        call.answer()
    }

    func decline() {
        call.hangup()
    }

    func callDidEstablish(call: SINCall!) {
        print("callDidEstablish")
    }

    func callDidEnd(call: SINCall!) {
        print("callDidEnd")
    }

    func callDidProgress(call: SINCall!) {
        print("callDidProgress")
        self.audioController.startPlayingSoundFile(self.pathForSound("ringback.wav") as String, loop: true)
    }

    func callDidAddVideoTrack(call: SINCall!) {
        print("callDidAddVideoTrack")
        mainView.videoView.addSubview(self.videoController.remoteView())
    }


}

问题是，当我尝试从我的应用程序调用其他手机时，我的应用程序没有任何反应（didReceiveIncomingCall委托方法根本没有被调用）

如果我尝试从我的应用程序调用SinchVideo示例应用程序，则视频通话启动正常。但是，当我从SinchVideo应用程序调用我的应用程序时，我的应用程序中没有任何反应。所以我可能忘记在通话时添加一些通知或其他东西来告诉我的应用。如果你能帮到我，我将非常感激。感谢

编辑：我设法使didReceiveIncomingCall工作，但现在call.answer不工作。（当调用call.answer并且我看到我的手机正在振铃时没有任何反应）

Answer 1

我不确定DNMMainNC在收到来电时做了什么，

let sinchNC = DNMMainNC(rootViewController: sinchVC) What does DNMMainNC do?
sinchVC.call = call  // private var?

但是从代码中设置一个私有var调用看起来有点奇怪，如果它不是公共的，或者像init一样有构造函数但是有一个调用

Sinch视频不想在iOS上工作（Swift）
