Multiple UNUserNotifications not firing - ios

Question

I'm setting multiple UNUsernotifications as below,
- (void)viewDidLoad {
[super viewDidLoad];
notifCount = 0;
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!error) {
NSLog(#"request succeeded!");
[self set10Notif];
}
}];
}
In the set10Notif method, I'm setting multiple(8 for testing) notifications with time 10 seconds from current time.
-(void) set10Notif
{
notifCount = notifCount+1;
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"10.0") && notifCount < 10)
{
// create actions
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
[calendar setTimeZone:[NSTimeZone localTimeZone]];
NSDate *fireD = [[NSDate date] dateByAddingTimeInterval:notifCount*10];
NSString *fireStr = [self returnStringFromDate:fireD withFormat:#"hh/mm/ss dd/MM/yyyy"];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay|NSCalendarUnitHour|NSCalendarUnitMinute|NSCalendarUnitSecond|NSCalendarUnitTimeZone fromDate:fireD];
UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];
objNotificationContent.title = [NSString localizedUserNotificationStringForKey:#"Notif!" arguments:nil];
objNotificationContent.body = [NSString localizedUserNotificationStringForKey:fireStr
arguments:nil];
objNotificationContent.sound = [UNNotificationSound defaultSound];
UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:#"Prayer"
content:objNotificationContent trigger:trigger];
UNUserNotificationCenter *userCenter = [UNUserNotificationCenter currentNotificationCenter];
[userCenter addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if (!error) {
NSLog(#"Local Notification succeeded");
}
else {
NSLog(#"Local Notification failed");
}
[self set10Notif];
}];
#endif
}
}
All the local notifications are set. But only one notification got fired in the device, that's the last one.
Why can't the multiple notifications are not firing?
What did I do wrong?

Answer 1

Give a different "requestWithIdentifier" and "time delay" for each notification and try, may it works for you.
