UILocalNotification接收带有NSYearCalendarUnit的repeatInterval的通知（将触发日期移动到下一个触发日期）

Question

I set the repeatInterval of my notification to NSYearCalendarUnit. When I received the notification, I see this notification information that I log:

fire date = Tuesday, 13 May, 2014... next fire date = Wednesday, 13 May, 2015

Then I cancel the notification thinking that it will move the fire date to May 13 2015

[application cancelLocalNotification:locationNotification];

but it didn't... It really cancels the notification.

But when I didn't cancel the notification, the notification is retained however my fire date remains the same, I want it to move to 2015 and the next fire date to move to 2016

fire date = Tuesday, 13 May, 2014... next fire date = Wednesday, 13 May, 2015

Answer 1

You should update the fire date of the notification.

Try with this:

// Maybe in your code you don't need this, but I write it anyway
[application cancelLocalNotification:locationNotification];

// This will create a new date one year past the current notification fire date
NSDateComponents * components = [[NSDateComponents alloc] init];
components.year = 1;
NSDate * newDate = [[NSCalendar currentCalendar] dateByAddingComponents:components toDate:localNotification.fireDate options:kNilOptions];

// Now you can update the localNotification fire date
localNotification.fireDate = newDate;

// Schedule it. Again, maybe you don't need this in your code
[application scheduleLocalNotification:localNotification];
