Local Notification every specific day of week

问题:

I need to create a local notification for a specific time (example at 18.00) fired every working day of week (not Saturday and Sunday) but I can't find examples or tutorial. I want use with swift2.1. How can I create this notification? My problem is define the firedate correctly of the notification

You can use NSDateComponents to create the exact date for your local notification. Here is the example, how do we create local notification with exact fire date:

NSDate *now = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitWeekOfYear|NSCalendarUnitWeekday fromDate:now];//get the required calendar units

if (components.weekday>2) {
    components.weekOfYear+=1;//if already passed monday, make it next monday
}
components.weekday = 2;//Monday
components.hour = 11;
NSDate *fireDate = [calendar dateFromComponents:components];

UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = fireDate;
localNotification.alertBody = @"alert message";
localNotification.applicationIconBadgeNumber = 1;
localNotification.repeatInterval = NSCalendarUnitWeekOfYear;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

In this piece of code, I set the fire date to every Monday 11 a.m, and set it repeat weekly using repeatInterval of local notification. Code maybe wrong, need to test, but I guess this gives you the basic idea, also I don't code in swift, so it's objective c. Hope this helps!
