（UILocalNotification）iPhone报警应用程序 - 通知问题

Question

我正处于开发iPhone闹钟应用程序的最后阶段

警报通过通知中心

但是，如果闹钟设置为激活＆gt; 8小时后警报通知不会激活

有人知道设置通知是否有时间限制？

是否将应用程序置于前台

我真的很感激一些想法或建议，我们必须在一天内重新提交苹果

谢谢！

-(void)addLocalNotification:(myAlarmData *)ma WeekDay:(int)mweekday

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

    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

    NSDate *now = [NSDate date];

    NSDateComponents *dcom = [gregorian components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit |NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit | NSWeekdayCalendarUnit) fromDate:now];

    [dcom setWeekday:mweekday];
    [dcom setHour:ma.mHour];
