ios - iphone 应用程序中的通知

Question

我已经阅读了很多通知帖子，但不知何故我在某处出错了，所以这就是我发布这个问题的原因。我想在我的应用程序中每天早上 9 点收到通知。我在上午 9 点正确地收到它，没有任何问题，但困难是我在凌晨 2 点也收到同样的通知。我尝试使用以下代码。谁能告诉我哪里出错了。或者是ios6的问题。任何形式的帮助将不胜感激。谢谢你。

    NSString *day =@"9:00 AM";
    NSDateFormatter *dateFormat = [[[NSDateFormatter alloc] init]autorelease];
    [dateFormat setDateFormat:@"hh:mm a"];
    //NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
    //[dateFormat setTimeZone:gmt];
    NSDate *today=[dateFormat dateFromString:day];
    NSLog(@"string %@ & date %@",day,today);
    Class cls = NSClassFromString(@"UILocalNotification");
    if (cls != nil)
    {
        // delObj.QCouter=delObj.QCouter+1;

        //[[UIApplication sharedApplication] cancelAllLocalNotifications];
        notif = [[cls alloc] init];
        notif.fireDate =today;
        notif.timeZone = [NSTimeZone systemTimeZone];
         NSLog(@"timeZone %@ ",[NSTimeZone systemTimeZone]);
        notif.alertBody = @"You have a new letter ";
        notif.alertAction = NSLocalizedString(@"View", nil);;
        notif.soundName = @"Ding3.wav";
        notif.applicationIconBadgeNumber = 1;
        notif.repeatInterval = NSDayCalendarUnit;
        [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"Status"];
        NSDictionary *userDict = [NSDictionary dictionaryWithObject:@"You have a notifiaction"
                                                                       forKey:kRemindMeNotificationDataKey];
        notif.userInfo = userDict;
        // NSLog(@"userInfo %@",notif.userInfo);
        [[UIApplication sharedApplication] scheduleLocalNotification:notif];
        [notif release];
        [[NSUserDefaults standardUserDefaults] setObject:@"CurrentDay" forKey:@"DayChange"];
       }

您好，请尝试以下代码:-

    [[UIApplication sharedApplication] cancelAllLocalNotifications];
    NSDate *date = [NSDate date];
    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
    NSDateComponents *components = [gregorian components: NSUIntegerMax fromDate: date];
    [components setHour: 9];
    [components setMinute: 0];
    [components setSecond: 0];

    NSDate *today = [gregorian dateFromComponents: components];
    [gregorian release];

    Class cls = NSClassFromString(@"UILocalNotification");
    if (cls != nil)
    {
        notif = [[cls alloc] init];
        notif.fireDate =today;
        notif.alertBody = @"You have a new letter ";
        notif.alertAction = NSLocalizedString(@"View", nil);;
        notif.soundName = @"Ding3.wav";
        notif.applicationIconBadgeNumber = 1;
        notif.repeatInterval = NSDayCalendarUnit;
        [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"Status"];
        NSDictionary *userDict = [NSDictionary dictionaryWithObject:@"You have a notifiaction"
                                                                       forKey:kRemindMeNotificationDataKey];
        notif.userInfo = userDict;
        // NSLog(@"userInfo %@",notif.userInfo);
        [[UIApplication sharedApplication] scheduleLocalNotification:notif];
        [notif release];
        [[NSUserDefaults standardUserDefaults] setObject:@"CurrentDay" forKey:@"DayChange"];
       }
