UILocalNotification每15分钟一次，但不是在晚上（晚上10点以后）

I want to fire an UILocalNotification every 15 minutes. That is no problem:

我想每15分钟发一次UILocalNotification。那没问题：

    UILocalNotification *notification = [[UILocalNotification alloc] init];

    notification.fireDate = [[NSDate date] dateByAddingTimeInterval:15];
    notification.repeatInterval = NSMinuteCalendarUnit;



    notification.alertBody = NSLocalizedString(@"Alert", @"");
    notification.timeZone = [NSTimeZone defaultTimeZone];
    notification.soundName = UILocalNotificationDefaultSoundName;

    [[UIApplication sharedApplication] scheduleLocalNotification:notification];

But I would like to do that only between 8am and 10pm. How can I handle that?

但我想在上午8点到晚上10点之间做到这一点。我该怎么处理？

You will have to use repeaInterval, you probably think of repeat the notification every 15 min, but you have a problem if you want to skip hours. You could also schedule all notifications for one day (add one for 7:00am, 7:15am, 7:30am, etc) and repeat them for an interval of 1 day. If you want 4 notifications per hour, from 7am to 10pm that makes 60 notifications (which is under the max 64).

您将不得不使用repeaInterval，您可能会想到每15分钟重复一次通知，但如果您想跳过几小时，则会遇到问题。您还可以安排一天的所有通知（在上午7:00，上午7:15，上午7:30等添加一个）并重复1天的间隔。如果您希望每小时发送4个通知，则从早上7点到晚上10点会发出60个通知（最多64个通知）。
