pushRegistry(:didUpdate:for)未被调用

Question

我已经查看了所有有关这方面的问题，但是这些问题的答案已经应用到我的项目中，但是pushRegistry()委托方法并没有被调用。

首先，这是代码：

import UIKit
import PushKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, PKPushRegistryDelegate {

var window: UIWindow?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    print("App Launched");
    self.registerVoIPPush();
    return true
}

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

    if type == PKPushType.voIP {
        let tokenData = pushCredentials.token
        let voipPushToken = String(data: tokenData, encoding: .utf8)
        print(voipPushToken);
        //send token to server
    }
}

func registerVoIPPush() {
    print("registerVoIPPush");
    let voipPushResgistry = PKPushRegistry(queue: DispatchQueue.main)
    voipPushResgistry.delegate = self
    voipPushResgistry.desiredPushTypes = [PKPushType.voIP]
}


func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) {
    print(payload);
    ATCallManager.shared.incommingCall(from: "jane@example.com", delay: 0)
   }
}

i还启用了以下应用程序功能：-推送通知-后台模式-后台获取-远程通知- IP语音

我正在使用Xcode11.3 &使用iOS13.2构建

在供应门户上，已为应用程序id启用了推送通知。(已经生成了一个VoIP推送证书&也导入到了密钥链访问中，但显然还不能使用它来发送推送)。

任何帮助都将是非常感谢的，因为我正试图做到这一点，从过去的3天。

1. 您的PKPushRegistry对象在registerVoIPPush()方法完成后立即被释放，检查是否设置了适当的背景模式
