Question

How to notify every month notification.

-(void)applicationDidEnterBackground:(UIApplication *)application {

        NSDateFormatter *format = [[NSDateFormatter alloc] init];
        format.dateFormat = @"dd-MM-yyyy";
        NSComparisonResult result = [[format stringFromDate:[NSDate new]] compare:[format stringFromDate:[self lastDayOfMonthOfDate:[NSDate date]]]];
        if (result == NSOrderedSame){
            if (![USERDEFAULTS boolForKey:@"IS_MONTH"]) {
                [self getNotifiedForEveryMonth:nil];
            }}
        else{
            [USERDEFAULTS setBool:NO forKey:@"IS_MONTH"];
        }
    }

// getNotifiedForEveryMonth

-(void)getNotifiedForEveryMonth:(id)userinfo{
        // Schedule the notification
    [USERDEFAULTS setBool:YES forKey:@"IS_MONTH"];
    UILocalNotification* localNotification = [[UILocalNotification alloc] init];
    localNotification.fireDate = [NSDate date];
    localNotification.alertBody = @"Every Month Notificiation";
    localNotification.alertAction = @"Show me the item";
    localNotification.timeZone = [NSTimeZone defaultTimeZone];
 }

-(NSDate*)lastDayOfMonthOfDate:(NSDate *)date
{
        //    NSGregorianCalendar
    NSInteger dayCount = [self numberOfDaysInMonthCountForDate:date];
    NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
    [calendar setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
    NSDateComponents *comp = [calendar components:
                              NSCalendarUnitYear |
                              NSCalendarUnitMonth |
                              NSCalendarUnitDay fromDate:date];
    [comp setDay:dayCount];
    return [calendar dateFromComponents:comp];
}

-(NSInteger)numberOfDaysInMonthCountForDate:(NSDate *)date
{
    NSCalendar *calendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
    [calendar setTimeZone:[NSTimeZone timeZoneWithName:TIME_ABSOLUTE]];
    NSRange dayRange = [calendar rangeOfUnit:NSCalendarUnitDay
                                      inUnit:NSCalendarUnitMonth
                                     forDate:date];
    return dayRange.length;
}

So basically you want to throw a notification on last day of every month? — Harsh, Aug 13 '16 at 20:23
Why did you throw notification when your application goes to the background? — Harsh, Aug 13 '16 at 20:32
Its to get back into application, say you got some stuff to do with application. What if the user delete the notification, and still want him to throw the notification if application is in background. for every monthly bases. — KkMIW, Aug 13 '16 at 20:40

1) If you want fire notifications every month, even if user didn't open an app more then month, you should set several notifications (up to 60). For example, set notifications for next 12 month.

2) You should set notifications by this code (on loop, 12 times):

[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

3) Before you set new notifications, remove old with this code:

[[UIApplication sharedApplication] cancelAllLocalNotifications];
