iOS 11 didRegisterForRemoteNotificationsWithDeviceToken未调用

Question

After calling registerForRemoteNotifications the appDelegate method didRegisterForRemoteNotificationsWithDeviceToken is not called. I don't receive a token from APNs so I cannot receive push notifications.

I see the 'Allow' pop up, but after selecting allow, I don't get the usual response from didRegisterForRemoteNotificationsWithDeviceToken.

Everything used to work prior to IOS 11.

Is anyone else experiencing the same issue? There doesn't seem to be a lot of complaints about my issue.

Has anything changed in IOS 11 as far as the APNs registration process? Also didReceiveRemoteNotification in IOS 10 isn't working when the app is running in the background.

Ive searched high and low for a fix, but Push notifications are just broken for me at the moment for IOS 11.

I have all the Info.plist data set correctly. I have all the switches set in the project settings. I have tested previous versions of our app. I have created a bare bones project and it doesn't work either, just like our production app. I'm assuming the registration code is the same as IOS 10.

SOS please! Thanks.

In AppDelegate class method didFinishLaunchingWithOptions you have to use Code --

if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) )
    {
        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound |    UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
        [[UIApplication sharedApplication] registerForRemoteNotifications];

        if( optind != nil )
        {
            NSLog( @"registerForPushWithOptions:" );
        }
    }
    else
    {
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error)
         {
             if( !error )
             {
                 [[UIApplication sharedApplication] registerForRemoteNotifications];  // required to get the app to do anything at all about push notifications
                 NSLog( @"Push registration success." );
             }
             else
             {
                 NSLog( @"Push registration FAILED" );
                 NSLog( @"ERROR: %@ - %@", error.localizedFailureReason, error.localizedDescription );
                 NSLog( @"SUGGESTIONS: %@ - %@", error.localizedRecoveryOptions, error.localizedRecoverySuggestion );
             }
         }];
    }

I tried this solution as well with no success.

Our team actually solved the issue. A team member noticed didRegisterForRemoteNotificationsWithDeviceToken was working with Xcode 9 and IOS 11.

After simply plugging in my iPhone 6s plus device into his computer and running the app, the issue went away.

The device now receives didRegisterForRemoteNotificationsWithDeviceToken.

I'm chalking this one up to some IOS update weirdness.

Thanks for your help.
