Push notification 推送令牌'；s delegte方法在ios 12.4.5版iPhone 5s中未特别调用

我在我的应用程序中集成了VoIP和远程通知，但具体来说，是在iPhone 5s和ios 12.4.5中。我确实得到了VoIP令牌或远程令牌。UIApplicationDelegate的toke方法和PKPushRegistryDelegate的token方法未调用。这里出了什么问题？我已经尝试使用强大的蜂窝网络，而不是使用wifi连接。iPhone的其他变体，如iPhone 6和iPhone XR，工作正常。请帮我解决这个问题

我使用了一个推送通知证书，下面提到了远程推送和VoIP推送

这是我的密码

        UNAuthorizationOptions options = UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge;
        center.delegate = self;

        [center requestAuthorizationWithOptions:options completionHandler:^(BOOL granted, NSError * _Nullable error){

            if( !error ){

                dispatch_async(dispatch_get_main_queue(), ^{

                    [self voipRegistration];

                    [UIApplication.sharedApplication registerForRemoteNotifications];

                });
            }
        }];

        }];

这里也有同样的问题。。。我正在浪费很多时间调试这个。这里也有同样的问题。。。我正在浪费很多时间调试这个。
