Ios8 ios 8 UILocalNotification丢失，仅声音

我在应用程序中安排本地通知，如下所示：

UILocalNotification * notification = [UILocalNotification new];
notification.applicationIconBadgeNumber = 1;
notification.repeatInterval = NSCalendarUnitMinute;
notification.fireDate = date;
notification.timeZone = DEFAULT_TIME_ZONE;
notification.alertBody = alertBody;
notification.alertAction = @"View";
notification.soundName = @"my_sound";
notification.userInfo = userInfoDict;

[[UIApplication sharedApplication] scheduleLocalNotification:notification];

在最新版本的ios 8 gm上，我可以听到通知的声音，但是没有警报，通知中心没有消息等等。 我加入了

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions:

   ....
   if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {

    //ios 8
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:

                                                        UIUserNotificationTypeAlert |
                                                        UIUserNotificationTypeBadge |
                                                        UIUserNotificationTypeSound
                                                                                         categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
}

但是用户在第一次运行时不会发出请求权限的警报
