ios - PushKit PKPushRegistryDelegate 没有得到回调

Question

将我的应用程序升级到 Xcode8/Swift 3 后，我不再收到来自 PKPushRegistryDelegate 的回调。

我已经验证了 Apple´s Voice Over IP (VoIP) Best Practices 中的所有步骤.

我的设备记录了以下可能相关的信息:

callservicesd[92] : [WARN] Ignoring voipRegister request because either no bundleIdentifier could be determined (0) or no environment could be determined (1)

我的 AppDelegate:

var voipRegistry: PKPushRegistry!

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
  voipRegistry = PKPushRegistry(queue: DispatchQueue.main)    
  voipRegistry.delegate = self    
  voipRegistry.desiredPushTypes = Set([.voIP])    
}

extension AppDelegate: PKPushRegistryDelegate {    
    func pushRegistry(_ registry: PKPushRegistry, didInvalidatePushTokenForType type: PKPushType) {        
        print("didInvalidatePushTokenForType")        
    }

    func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, forType type: PKPushType) {        
        print("Incoming voip notfication: \(payload.dictionaryPayload)")
    }

    func pushRegistry(_ registry: PKPushRegistry, didUpdate credentials: PKPushCredentials, forType type: PKPushType) {               
        print("voip token: \(credentials.token)")        
    }   
}

我想我必须在目标的功能下启用“推送通知”:
