我有一个允许设备运行更新的代码。当ipad不受iOS11下的信息引导访问(并且在iOS10和引导访问下工作)时,它可以正常工作:

- (void)viewDidLoad
{
...
      UNMutableNotificationContent* content = [[UNMutableNotificationContent alloc] init];
        content.title = [NSString localizedUserNotificationStringForKey:@"Update!" arguments:nil];
        content.body = [NSString localizedUserNotificationStringForKey:@"Update!"
                                                             arguments:nil];

        // Configure the trigger for a 7am update.
        NSDateComponents* date = [[NSDateComponents alloc] init];
        date.hour = 18;
        date.minute = 31;
        UNCalendarNotificationTrigger* trigger = [UNCalendarNotificationTrigger
                                                  triggerWithDateMatchingComponents:date repeats:NO];

        // Create the request object.
        UNNotificationRequest* request = [UNNotificationRequest
                                          requestWithIdentifier:@"update" content:content trigger:trigger];

        UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
            if (error != nil) {
                NSLog(@"%@", error.localizedDescription);
            }
        }];
    }

    - (void)userNotificationCenter:(UNUserNotificationCenter *)center
           willPresentNotification:(UNNotification *)notification
             withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler {
        // Update the app interface directly.
        NSLog(@"");
        // Play a sound.
        completionHandler(UNNotificationPresentationOptionSound);
    }

我发现Ticket,但没有详尽的解释来完成它:

在iOS11下是否可以在引导访问时启动通知?

答案 0 :(得分:1)

看起来这只不过是iOS 11.2.5 beta 4中修复的iOS错误。有关详细信息,请参阅我自己的问题here

如果您可以等到iOS 11.2.5发布(希望很快就会according to Apple),问题应该自行解决。否则,您需要调查类似套接字系统的内容。
