Cancelling a specific UILocalNotification

Question

I have this code for local notification, and I have a scheduleNotification and clearNotification using my own method. These are the codes:

- (void)clearNotificat         


        

Answer 1

I would suggest using the userInfo property on UILocalNotification, as others have mentioned. A simpler implementation that the accepted answer would be:

for(UILocalNotification* notification in [[UIApplication sharedApplication]scheduledLocalNotifications])
{
       if([[notification.userInfo objectForKey:@"notification_identifier"] isEqualToString:@"notification_001"])
       {
            [[UIApplication sharedApplication] cancelLocalNotification:notification];
       }
}

A for loop like this is much simpler. I'm not sure if it's more or less optimal, but it's certainly easier to read, and I assume you only have a few notifications to loop through anyway.
