在iOS 13上未获取APNS设备令牌

问题描述

我有与APNS设备令牌有关的问题.在我使用Xcode 10.2和iOS 12.1之前.这时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

我正在这样注册APNS，并且运行正常.

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设备上并使用Xcode 11时，不会调用委托方法didRegisterForRemoteNotificationsWithDeviceToken.无法理解此问题.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，但是在我的情况下，甚至没有调用委托方法.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.
