Question

My App needs to trigger alarms at weekdays only.
My idea was to schedule notifications for each day, but the problem is that I read that 64 scheduled notifications are the maximum you can have and with my notifications there will be a total of 120 notifications so this can’t be done.

Now I’m wondering if there is a way to cancel all the notifications on Saturday and Sunday instead.

The code I am using now that repeats the notification in weekends to:

NSDateComponents *comps = [[NSDateComponents alloc] init];
    [comps setHour:8];
    [comps setMinute:25];
    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    NSDate *fireDate = [gregorian dateFromComponents:comps];

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

    alarm.fireDate = fireDate;
    alarm.repeatInterval = NSDayCalendarUnit;
    alarm.soundName = @"sound.aiff";
    alarm.alertBody = @"Message..";
    alarm.timeZone = [NSTimeZone defaultTimeZone];
    [[UIApplication sharedApplication] scheduleLocalNotification:alarm];

Look at [UIApplication scheduledLocalNotifications], you have all notification scheduled.

It’s an array of UILocalNotification.

Make a loop with this array and look at the date fireDate of the notification, and do :

[UIApplication cancelLocalNotification:theNotificationToDelete];
