在ios10中添加本地通知 - swift 3

Question

编辑:所以把应用程序放在后台就行了.

原版的:

所以我一直在尝试向新的UNUserNotificationCenter添加通知,但我似乎没有得到它.

我的视图控制器有一个动作:

@IBAction func sendPressed(_ sender: AnyObject) {
    let content = UNMutableNotificationContent()

    content.title = "Hello"
    content.body = "What up?"
    content.sound = UNNotificationSound.default()

    // Deliver the notification in five seconds.
    let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)
    let request = UNNotificationRequest.init(identifier: "FiveSecond", content: content, trigger: trigger)

    // Schedule the notification.
    let center = UNUserNotificationCenter.current()
    center.add(request) { (error) in
        print(error)
    }
    print("should have been added")
}

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    let center = UNUserNotificationCenter.current()
    center.requestAuthorization([.alert, .sound]) { (granted, error) in
    }
}

而且我Notification Content Extension在项目中也有一个,但它似乎根本没有被触发,任何想法我都缺少了？我正在尝试用户文档中的示例,但它并没有告诉我更多或者我错过了它.

你需要注册通知...我试过,这是有效的.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.
        let center = UNUserNotificationCenter.current()
        center.requestAuthorization([.alert, .sound]) { (granted, error) in
            // Enable or disable features based on authorization.
        }
        return true
    }

编辑:您不需要将您的应用程序放在后台,以显示iOS 10以后的通知.

使用下面的回调配置通知以显示在前台.

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)

这是一个示例项目.

使用Objective-C实现:

我在这里写了一个Demo项目: iOS10AdaptationTips.

1. 导入UserNotifications

   ///Notification become independent from Foundation
   @import UserNotifications;
   

2. 请求localNotification的授权

   UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
   [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
                         completionHandler:^(BOOL granted, NSError * _Nullable error) {
                             if (!error) {
                                 NSLog(@"request authorization succeeded!");
                                 [self showAlert];
                             }
                         }];
   

   请求授权:

3. 安排localNotification

4. 更新应用程序图标徽章编号

       //        //Deliver the notification at 08:30 everyday
       //        NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
       //        dateComponents.hour = 8;
       //        dateComponents.minute = 30;
       //        UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:dateComponents repeats:YES];
   
       UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
       content.title = [NSString localizedUserNotificationStringForKey:@"Elon said:" arguments:nil];
       content.body = [NSString localizedUserNotificationStringForKey:@"Hello Tom?Get up, let's play with Jerry!"
                                                            arguments:nil];
       content.sound = [UNNotificationSound defaultSound];
   
       /// 4. update application icon badge number
       content.badge = @([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1);
       // Deliver the notification in five seconds.
       UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger
                                                     triggerWithTimeInterval:5.f repeats:NO];
       UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"FiveSecond"
                                                                             content:content trigger:trigger];
       /// 3. schedule localNotification
       UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
       [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
           if (!error) {
               NSLog(@"add NotificationRequest succeeded!");
           }
       }];
   

然后它会显示如下:

如果默认情况下重复只显示一个 而不是在iOS9的锁定屏幕上显示多个:http://i67.tinypic.com/98t75s.jpg 并自动支持3D Touch http://a67.tinypic.com/dorw3b.jpg
