iOS create local notification when app exit with 10 days - ios

Question

I am create a local notification with 10 days and at 15:30 when app exit. Here is a code:
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *now = [NSDate date];
float day = 10;
NSDate *newDate = [now dateByAddingTimeInterval:60*60*24*day];
NSDateComponents *componentsForFireDate = [calendar components:(NSYearCalendarUnit | NSWeekCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit | NSWeekdayCalendarUnit) fromDate: newDate];
[componentsForFireDate setHour: 15];
[componentsForFireDate setMinute:30];
[componentsForFireDate setSecond:0];
NSDate *fireDateOfNotification = [calendar dateFromComponents:componentsForFireDate];
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = fireDateOfNotification;
localNotification.repeatInterval = NSWeekCalendarUnit;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
When I try change date & time in the my phone to the next day (now + 1), It's still show notification, next day, still show. I want local notification show each 10 days when app exit. Any suggests to fix this problems ?

Answer 1

try this code: your app open after 10 day notification fire and other 1 day fire.
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *componentsForFireDate = [calendar components:( NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit | NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear) fromDate: [NSDate date]];
componentsForFireDate.day = componentsForFireDate.day + 10;
[componentsForFireDate setHour: 15];
[componentsForFireDate setMinute:30];
[componentsForFireDate setSecond:0];
NSDate *fireDateOfNotification = [calendar dateFromComponents:componentsForFireDate];
NSLog(#"Date: %#",fireDateOfNotification);
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = fireDateOfNotification;
localNotification.alertBody = #"This is local notification!";
localNotification.repeatInterval = NSCalendarUnitDay;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
hope this code help you.

After changing the time in your system, please check the simulator time also. initially it not updated.
In simulator settings, General->language & region-> Advanced-> Automatica switch will be on mode. select off and on. then you simulator time will also change
