Say today is a Monday and it's 1 PM. I want to schedule a weekly local notification from my iOS app starting today at 2 PM. I'd do this:
NSDateComponents *components = [[[NSDateComponents alloc]init]autorelease];
components.weekday = 2;
components.hour = 14;
components.minute = 0;
UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:YES];
//then make a UNMutableNotificationContent and UNNotificationRequest and schedule it
But if I want to start it next Monday at 2 PM, how do I skip the first occurrence?
To ask the question another way, how do I schedule a repeating UNCalendarNotificationTrigger starting at some arbitrary time, instead of the first occurrence of the repeat interval?
