WatchOS App 4.0：如何安排本地通知

问题描述

我的应用程序处于后台或非活动模式，然后本地通知不起作用。我从未收到过关于观看的本地通知。

My application in background or inactive mode then local notification not work. I have never receive local notification on watch.

更新：少于3分钟安排本地通知它工作正常但超过3分钟它不起作用。那么如何解决这个问题？

Update: less then 3 minutes schedule a local notification it's work fine but more then 3 minutes it's not work. so how to resolve this issues?

根据我的理解我的代码如下。

As per my understanding 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);
    }
}];

感谢任何建议或想法。

推荐答案

确保您的iphone已锁定。当涉及通知时，它关于在何处提供该通知的偏好。

Make sure your iphone is locked. When it comes to notification, its about preference where to deliver that notification.

在模拟器上运行您的手表应用程序，从iPhone模拟器安排通知并锁定iPhone模拟器屏幕，保持手表模拟器处于活动状态，在这种情况下通知是触发后，它将在您的手表模拟器上发布。当您在实际设备上进行测试时也是如此。

当iphone和手表都被锁定时，首选是iphone。

And when both iphone and watch is locked, preference is iphone.
