iOS PushKit注册不适用于iOS10

Question

我正在为iOS 10的VoIP应用程序实现PushKit 。

我已经在AppDelegate.swift文件中编写了以下代码：

import PushKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, PKPushRegistryDelegate {

var window: UIWindow?
private let _pushRegistry = PKPushRegistry(queue: DispatchQueue.main)

//MARK: - App Life Cycle -
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    //Register for local notifications
    NotificationController.registerNotifcationForApplication()

    //PushKit
    _pushRegistry.delegate = self
    var typeSet = Set<PKPushType>()
    typeSet.insert(.voIP)
    _pushRegistry.desiredPushTypes = typeSet

    window!.makeKeyAndVisible()
    return true
}

//MARK: - Delegates -
func pushRegistry(_ registry: PKPushRegistry, didUpdate credentials: PKPushCredentials,  forType type: PKPushType) {
    DDLogVerbose("PushKit Token: \(credentials.token) length: \(credentials.token.count)")
    print("pushRegistry didUpdate credentials")
}

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

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

}

我启用了以下背景模式：

但是当我启动应用程序时， 没有任何代表被调用 。
在iOS 9上也无法使用。

我只是通过在以下功能中启用“ Push Notifications来解决此问题：

其实我也已经尝试过了，但是以前没有用。 现在，我启用了它，关闭了Xcode 8.2.1，重新打开，清理生成，它开始工作了！
