Sinch VoIP ManagedPush通知无效(Swift)

Question

我一直在尝试实现VoIP ManagedPush通知，但是它们不起作用。以下是我为实现ManagedPush所采取的步骤：

1)在Apple中创建了一个VoIP服务证书。将证书的.p12文件上载到Sinch。

2)实例化sinchClient和push客户机var sinchClient: SINClient!; var push: SINManagedPush!

3)在didFinishLaunchingWithOptions函数中初始化push客户端和sinch客户端：

    // Register for Sinch Notifications (for calling)
    self.push = Sinch.managedPushWithAPSEnvironment(.Development)
    self.push.delegate = self
    self.push.setDesiredPushTypeAutomatically()

    // Sinch
    NSNotificationCenter.defaultCenter().addObserverForName("UserDidLoginNotification", object: nil, queue: nil, usingBlock: {(note: NSNotification) -> Void in
        self.initializeSinch(note.userInfo!["userId"] as! String)
    })

4)初始化sinchClient。当用户通过facebook登录时被调用。

func initializeSinch(loginId: String){
    sinchClient = Sinch.clientWithApplicationKey("key", applicationSecret: "secret", environmentHost: "sandbox.sinch.com", userId: loginId)
    sinchClient.callClient().delegate = self
    sinchClient.setSupportCalling(true)
    sinchClient.enableManagedPushNotifications()
    sinchClient.start()
    sinchClient.startListeningOnActiveConnection()
    self.push.registerUserNotificationSettings()
}

5)在函数didRegisterForRemoteNotificationsWithDeviceToken中，我放置了以下代码行：

self.push.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)

6)在函数didRecieveRemoteNotification中，我放置了以下代码行：

self.push.application(application, didReceiveRemoteNotification: userInfo)

7)为SINManagedPushDelegate创建委托函数

extension AppDelegate: SINManagedPushDelegate{
     func managedPush(managedPush: SINManagedPush!, didReceiveIncomingPushWithPayload payload: [NSObject : AnyObject]!, forType pushType: String!) {
         self.handleRemoteNotification(payload)
         print("HERE GOT A REMOTE NOTIFICATIOn")
     }
     func handleRemoteNotification(userInfo: [NSObject : AnyObject]) {
         if (sinchClient == nil) {
             let userManager = UserManager()
             initializeSinch(String(userManager.user.facebookId))
         }
         self.sinchClient.relayRemotePushNotification(userInfo)
     }     
}

因此，我的问题真的归结为我做错了什么，ManagedPush没有工作。我读过SinchCallingPush，并对其进行了转换，并试图完全按照代码执行，但它仍然不起作用。我认为这可能与不实现PushKit有关。如果是这样的话，请有人指出如何正确地导入它以及在哪里使用它。

出了点事就开始起作用了。现在，我收到了一个错误，上面写着SIN_INCOMING_CALL。我相信我可以搜索并解决这个问题。
