在ios10中添加本地通知 - swift 3

Question

编辑： 因此，将应用程序置于后台的方法确实有效。

原文：

所以我一直在努力的通知添加到新UNUserNotificationCenter，但我似乎并没有得到它。

我的视图控制器具有一个动作：

@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 
    } 
} 

而且我在项目Notification Content Extension为好，但它似乎并没有在所有触发，任何想法是什么我失踪？我正在尝试用户文档中的示例，但它没有告诉我更多，或者我错过了它。

您需要为通知注册...我想和这个作品。

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：你不需要把你的应用程序在后台从iOS的10起PRESENT通知。

使用下面的回调来配置前台通知。

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

Here是一个示例项目。

用Objective-C的implemation：

我在这里写了一个演示项目：iOS10AdaptationTips。

1. 进口UserNotifications

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

2. 为localNotification

   请求授权

   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. 时间表localNotification

4. 更新应用程序图标徽章数量

   //  //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!"); 
        } 
       }]; 
   

那么就会出现这样的：

背景： 锁屏：

如果重复用默认只显示一个 ，而不是显示在许多的iOS9锁定屏幕上： http://i67.tinypic.com/98t75s.jpg ，同时还支持3D触摸自动 http://a67.tinypic.com/dorw3b.jpg

Answer 3

我解决我的问题如下：（火力地堡，斯威夫特3）：

查找AppDelegate中此方法：

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

找到这行：

completionHandler() 

年底成立：如果你不能通过你的演示选项，以completionHandler方法

completionHandler([.alert,.sound,.badge]) 

通知不点火。
