WatchOS 4.0 App: How to Schedule Local Notification

Question

My application is in the background or in inactive mode, then the local notification does not work. I never get a local notice on a watch.

Update: for less than 3 minutes, a local notification is assigned, which works fine, but for more than 3 minutes it does not work. so how to solve these problems?

As I understand it, my code is as follows.

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;

// Objective-C
UNMutableNotificationContent *content = [UNMutableNotificationContent new];
content.title = [NSString localizedUserNotificationStringForKey:@"Remider!" arguments:nil];
content.body = [NSString localizedUserNotificationStringForKey:@"Your watch is out of range" arguments:nil];
content.sound = [UNNotificationSound defaultSound];

// Time
// 15 min
double timer = 15*60;
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:time
                                                                                                repeats:NO];
// Actions
UNNotificationAction *snoozeAction = [UNNotificationAction actionWithIdentifier:@"Track"
                                                                          title:@"Track" options:UNNotificationActionOptionForeground];

// Objective-C
UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"UYLReminderCategory"
                                                                          actions:@[snoozeAction] intentIdentifiers:@[]
                                                                          options:UNNotificationCategoryOptionCustomDismissAction];
NSSet *categories = [NSSet setWithObject:category];

// Objective-C
[center setNotificationCategories:categories];

// Objective-C
content.categoryIdentifier = @"UYLReminderCategory";

NSString *identifier = [self stringUUID];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier
                                                                      content:content trigger:trigger];

[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
    if (error != nil) {
        NSLog(@"Something went wrong: %@",error);
    }
}];

Evaluate if there is any suggestion or idea.

Make sure your iphone is locked. When it comes to notification, its preference is when to deliver this notification.
