未在 ios 13 上获取 APNS 设备令牌 [英] Not getting APNS Device token on ios 13

问题描述

我有与 APNS 设备令牌相关的问题.在我使用 Xcode 10.2 和 iOS 12.1 之前.这时候我曾经在委托方法中获取设备令牌

I have issue related to APNS device token . Before I was using Xcode 10.2 and iOS 12.1. At this moment I used to get the device token in delegate method

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken

我正在注册这样的 APNS，并且运行良好.

I am registering for APNS like this and it was working fine.

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
                if(!error){
                    [[UIApplication sharedApplication] registerForRemoteNotifications];
                }
    }];

现在，当将 iOS 13 安装到我的 iPhone 设备并使用 Xcode 11 时，不会调用委托方法 didRegisterForRemoteNotificationsWithDeviceToken.无法理解这个问题.我已经对此进行了研究，我知道从委托方法获取令牌有一些变化，但在我的情况下，委托方法甚至没有被调用.再次适用于 iOS 12.

Now when installed iOS 13 to my iPhone device and using Xcode 11 , the delegate method didRegisterForRemoteNotificationsWithDeviceToken is not called. Unable to understand this problem . I have already done research over this , I know there are some changes in getting token from the delegate method but in my case delegate method is not even called. Again it's working fine for iOS 12.
