后台的本地通知ios 11

Question

我用cordova编写了iOS应用程序，我使用了原始的Cordova插件进行本地通知。我在通知中心安排了大约90个本地通知。它在iOS 10上工作，但在iOS 11上并不总是，也不是每个设备上都能工作。

例如，在我的手机上，我看到了所有的通知-在前景和背景。

在另一部手机上，我只在前台看到通知(在应用程序中)，而不是在后台。

是iOS 11的错误吗？

更新-解决

用于本地通知的Cordova插件只能调度64个本地通知(如iOS文档限制)。因此，我需要为64个当前本地通知和数据库编写带有队列的本机模块，以便在限制之后设置下一个本地通知。

IOS 11尝试使用这个in - (void)applicationDidEnterBackground:(UIApplication *)应用程序

[self performSelectorInBackground:@selector(showNotical:) withObject:@"Open InBack"];

用方法

- (void) showNotical:(NSString*)msg <br>
{

    UIApplication *application = [UIApplication sharedApplication];

    if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])
    {
            //UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound) categories:nil];
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeSound) categories:nil];
        [application registerUserNotificationSettings:settings];

    }
    else // iOS 7 or earlier
    {
            //UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        [application registerForRemoteNotificationTypes:myTypes];
    }

    UILocalNotification* localNotification = [[UILocalNotification alloc] init];
        //    localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:1];
    localNotification.alertAction = @"test";
    localNotification.alertBody = [NSString stringWithFormat:@"%@",msg];
    localNotification.soundName = UILocalNotificationDefaultSoundName; // den den den
    localNotification.repeatInterval = 7;
        //[UIApplication sharedApplication].applicationIconBadgeNumber=1;
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

}
