无法从现在开始安排UILocalNotification x天

Question

我现在已经尝试了太多时间而没有找到问题/解决方案。此代码应该通过比较wd（选定的工作日）和item.itemDayName（当前工作日的Int）来计划从现在起x天的通知。现在，代码仅在wd == 7时有效，如wd == 7 - ＆gt;选择所有工作日（wd 0-6 = sun-sat）。我将非常感谢您提供的任何反馈，谢谢。

- (void)scheduleNotificationWithItem:(ToDoItem *)item andWeekday:(int)wd{
    NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
    NSDateComponents *dateComps = [[NSDateComponents alloc] init];

    if (wd < 7) {
        [dateComps setYear:item.itemYear];
        [dateComps setMonth:item.itemMonth];
        if (item.itemDayName != (wd + 1)) {
            int result = (wd + 1) - item.itemDayName;
            result = result + item.itemDay;
            [dateComps setDay:result];
        }
        else{
            [dateComps setDay:item.itemDay];
        }
    }
    else {
        [dateComps setYear:item.itemYear];
        [dateComps setMonth:item.itemMonth];
        [dateComps setDay:item.itemDay];
    }
    [dateComps setHour:item.itemHour];
    [dateComps setMinute:item.itemMinute];
    NSDate *itemDate = [calendar dateFromComponents:dateComps];

    UILocalNotification *localNotif = [[UILocalNotification alloc] init];
    if (localNotif == nil)
        return;
    localNotif.fireDate = itemDate;
    //localNotif.fireDate = [itemDate dateByAddingTimeInterval:-(1*60)];
    localNotif.timeZone = [NSTimeZone defaultTimeZone];
    if (wd < 7) {
        [localNotif setRepeatInterval: NSCalendarUnitWeekOfMonth];
    }
    else {
        [localNotif setRepeatInterval: NSCalendarUnitDay]; //Repeat daily
    }

    localNotif.alertBody = [NSString stringWithFormat:NSLocalizedString(@"Time to take %@!", nil),
                            item.itemName];
    localNotif.alertAction = NSLocalizedString(@"View Details", nil);
    localNotif.alertTitle = NSLocalizedString(@"Piller", nil);

    localNotif.soundName = UILocalNotificationDefaultSoundName;
    localNotif.applicationIconBadgeNumber = 1;

    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:item.itemName forKey:item.itemKeyName];
    localNotif.userInfo = infoDict;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
