watchOS 3上的本地通知未显示

Question

我对watchOS 3上的UNNotification有问题！

在watchOS 2和iOS 9中安排本地通知我使用WatchConnectivity 从手表我发送消息到iPhone和iPhone安排本地通知 当通知到达并且iPhone被锁定时，手表会复制通知，而WatchKit Extension中的NotificationController会调用方法

- (void)didReceiveLocalNotification:(UILocalNotification *)localNotification withCompletion:(void (^)(WKUserNotificationInterfaceType))completionHandler;

显示观看通知。

所以在watchOS 3中，我希望直接从手表发送和接收通知 一些代码

在watchKit Extension Target中添加UserNotifications.framework

在ExtensionDelegate中导入框架，添加UNUserNotificationCenterDelegate并请求授权

#import "ExtensionDelegate.h"
#import <UserNotifications/UserNotifications.h>

@interface ExtensionDelegate()<UNUserNotificationCenterDelegate>{
}
@end

@implementation ExtensionDelegate

- (void)applicationDidFinishLaunching {
    // Perform any final initialization of your application.

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

    [notifCenter requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error){

        if( !error ){
            // required to get the app to do anything at all about push notifications
        }
    }];

}

然后在InterfaceController中我安排UNNotification

- (IBAction)SendLocalNotification {

    UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
    content.title = [NSString localizedUserNotificationStringForKey:@“Test” arguments:nil];
    content.subtitle = [NSString localizedUserNotificationStringForKey:@“Local notification from Watch " arguments:nil];
    content.sound = [UNNotificationSound defaultSound];
    [content setValue:@YES forKeyPath:@"shouldAlwaysAlertWhileAppIsForeground"];

    UNTimeIntervalNotificationTrigger* timeTrigger = [UNTimeIntervalNotificationTrigger
                                                      triggerWithTimeInterval:10 repeats:NO];

    NSString *uuid = [[NSUUID UUID] UUIDString];

    UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:uuid
                                                                          content:content trigger:timeTrigger];

    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];

    [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
        if (!error) {
            NSLog(@" local notification scheduled”);
        }
    }];

}

（我在阅读this post后也会更新SendLocalNotification方法，但我还没有解决问题）

NotificationController中的

导入框架，这是代码

#import "NotificationController.h"

#import <UserNotifications/UserNotifications.h>
@interface NotificationController()

@end


@implementation NotificationController
@synthesize label;

- (instancetype)init {
    self = [super init];
    if (self){
        // Initialize variables here.
        // Configure interface objects here.
    }
    return self;
}

- (void)willActivate {
    // This method is called when watch view controller is about to be visible to user
    [super willActivate];
}

- (void)didDeactivate {
    // This method is called when watch view controller is no longer visible
    [super didDeactivate];
}


- (void)didReceiveNotification:(UNNotification *)notification
                withCompletion:(void(^)(WKUserNotificationInterfaceType interface)) completionHandler {
    // This method is called when a notification needs to be presented.
    // Implement it if you use a dynamic notification interface.
    // Populate your dynamic notification interface as quickly as possible.
    //
    // After populating your dynamic notification interface call the completion block.

    [label setText:notification.request.content.subtitle];
    completionHandler(WKUserNotificationInterfaceTypeCustom);
}


@end

在ExtensionDelegate中，我还实现了在应用程序处于前台时接收通知的方法

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
       willPresentNotification:(UNNotification *)notification
         withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
    NSLog(@“notification arrived in foreground");

    completionHandler(UNNotificationPresentationOptionAlert|UNNotificationPresentationOptionSound);
}

看起来一切都还不错......但

- 当手表应用程序在后台时，不会收到通知

- 当手表应用程序位于前台时，控制台会打印日志

notification arrived in foreground

但未显示通知

问题出在哪里？ 我错过了什么？

我希望有人可以帮助我!!

提前非常感谢!!
