iOS10--消息通知的基本使用

官方将通知单独放在了UserNotifications.framework，使用时需要导入框架。
UserNotifications.framework主要类文件：

UNCalendarNotificationTrigger
UNLocationNotificationTrigger
UNMutableNotificationContent
UNNotification
UNNotificationAction
UNNotificationAttachment
UNNotificationCategory
UNNotificationContent
UNNotificationRequest
UNNotificationResponse
UNNotificationServiceExtension
UNNotificationSettings
UNNotificationSound
UNNotificationTrigger
UNPushNotificationTrigger
UNTextInputNotificationAction
UNTextInputNotificationResponse
UNTimeIntervalNotificationTrigger
UNUserNotificationCenter

UNUserNotificationCenter的应用：

• 请求用户授权：
  

  UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];    
  // 请求授权    
  /*     
  UNAuthorizationOptionBadge   = (1 << 0),     
  UNAuthorizationOptionSound   = (1 << 1),     
  UNAuthorizationOptionAlert   = (1 << 2),     
  UNAuthorizationOptionCarPlay = (1 << 3),     
  */    
  [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {　　if(granted){

     if(granded)
       //同意
     }else{
       //不同意
     }

  }];

  
  补充：获取授权设置信息
  

  // 获取通知授权和设置    
  [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {        
  /*         
  UNAuthorizationStatusNotDetermined : 没有做出选择         
  UNAuthorizationStatusDenied : 用户未授权         
  UNAuthorizationStatusAuthorized ：用户已授权         
  */        
  if (settings.authorizationStatus == UNAuthorizationStatusNotDetermined) 
  {                       
        NSLog(@"未选择");                  
  }else if (settings.authorizationStatus == UNAuthorizationStatusDenied){                        
        NSLog(@"未授权");                   
  }else if (settings.authorizationStatus == UNAuthorizationStatusAuthorized){                      
        NSLog(@"已授权");        
  }       
  }]

• 创建本地通知：

  // 创建一个本地通知
  UNMutableNotificationContent *content_1 = [[UNMutableNotificationContent alloc] init];    
  // 主标题    
  content_1.title = [NSString localizedUserNotificationStringForKey:@"title" arguments:nil];    
  // 副标题    
  content_1.subtitle = [NSString localizedUserNotificationStringForKey:@"subtitle" arguments:nil];    
  content_1.badge = [NSNumber numberWithInteger:1];    
  content_1.body = [NSString localizedUserNotificationStringForKey:@"title_message_for_yan" arguments:nil];    
  content_1.sound = [UNNotificationSound defaultSound];    
  // 设置触发时间    
  UNTimeIntervalNotificationTrigger *trigger_1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO];    
  // 创建一个发送请求
  UNNotificationRequest *request_1 = [UNNotificationRequest requestWithIdentifier:@"my_notification" content:content_1 trigger:trigger_1];

  补充：

  • UserNotifications提供了三种触发器：
    

    UNTimeIntervalNotificationTrigger ：一定时间后触发
     
    UNCalendarNotificationTrigger ： 在某月某日某时触发
     
    UNLocationNotificationTrigger ： 在用户进入或是离开某个区域时触发

  • @“my_notification”请求的标识符可以用来管理通知：
    

    - 移除还未展示的通知
    [center removePendingNotificationRequestsWithIdentifiers: @[@“my_notification”]];
    [center removeAllPendingNotificationRequests]; // - (void)cancelAllLocalNotifications；
     
    - 移除已经展示过的通知
    [center removeDeliveredNotificationsWithIdentifiers:@[@“my_notification”]];
    [center removeAllDeliveredNotifications];
     
    - 获取未展示的通知
    [center getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) {
        NSLog(@"%@",requests);
    }];
     
    - 获取展示过的通知
    [center getDeliveredNotificationsWithCompletionHandler:^(NSArray<UNNotification *> * _Nonnull notifications) {
        NSLog(@"%@",notifications);
    }];

  • 远程通知的格式：

    { "aps":{ "alert":{ "title":"I am title", "subtitle":"I am subtitle", "body":"I am body" }, "sound":"default", "badge":1 } }

    具体请参考官方文档

• 将通知请求添加到通知中心（UNUserNotificationCenter）：

  [center addNotificationRequest:request_1 withCompletionHandler:^(NSError * _Nullable error) {
  
  }];

         

 

 

接收通知

• 处理通知：
  设置UNUserNotificationCenterDelegate：
  注意：UNUserNotificationCenter 的 delegate 必须在 application:willFinishLaunchingWithOptions: orapplication:didFinishLaunchingWithOptions: 方法中实现；

  center.delegate = self;

  • 应用内展示通知:

    - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
        // 如果不想显示某个通知，可以直接用空 options 调用 completionHandler: // completionHandler([])
        completionHandler(UNNotificationPresentationOptionBadge + UNNotificationPresentationOptionSound);
    }

  • 在用户与你推送的通知进行交互时被调用：
    

    - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
        completionHandler();
        NSLog(@"userInfo--%@",response.notification.request.content.userInfo);
    }

UNNotificationCategory的应用：

• 创建一个 category：
  

   
  /*
   
  UNNotificationActionOptionAuthenticationRequired = (1 << 0),
   
  UNNotificationActionOptionDestructive = (1 << 1), 取消
   
  UNNotificationActionOptionForeground = (1 << 2), 启动程序
   
  */
   
  UNTextInputNotificationAction *textAction = [UNTextInputNotificationAction actionWithIdentifier:@"my_text" title:@"text_action" options:UNNotificationActionOptionForeground textInputButtonTitle:@"输入" textInputPlaceholder:@"默认文字"];
   
  UNNotificationAction *action = [UNNotificationAction actionWithIdentifier:@"my_action" title:@"action" options:UNNotificationActionOptionDestructive];
   
  UNNotificationAction *action_1 = [UNNotificationAction actionWithIdentifier:@"my_action_1" title:@"action_1" options:UNNotificationActionOptionAuthenticationRequired];
   
  /*
   
  UNNotificationCategoryOptionNone = (0),
   
  UNNotificationCategoryOptionCustomDismissAction = (1 << 0),
   
  UNNotificationCategoryOptionAllowInCarPlay = (2 << 0),
   
  */
   
  UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"my_category" actions:@[textAction,action,action_1] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];
   
  NSSet *setting = [NSSet setWithObjects:category, nil];
   
  [center setNotificationCategories:setting];

• 在创建 UNNotificationContent 时把 categoryIdentifier 设置为需要的 category id 即可：

  content.categoryIdentifier = @"my_category";

  远程推送也可以使用 category，只需要在 payload 中添加 category 字段，并指定预先定义的 category id 就可以了

• 处理category的通知：
  

  - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
   
  completionHandler();
   
  NSLog(@"userInfo--%@",response.notification.request.content.userInfo);
   
  // 获取通知中心的所有的Categories
   
  [center getNotificationCategoriesWithCompletionHandler:^(NSSet<UNNotificationCategory *> * _Nonnull categories) {
   
  for (UNNotificationCategory *category in categories) {
   
  if ([category.identifier isEqualToString:@"my_category"] && [response.notification.request.content.categoryIdentifier isEqualToString:@"my_category"]) {
   
  for (UNNotificationAction *textAction in category.actions) {
   
  if ([textAction.identifier isEqualToString:@"my_text"]) {
   
  UNTextInputNotificationAction *text = (UNTextInputNotificationAction *)textAction;
   
  UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:text.textInputButtonTitle preferredStyle:UIAlertControllerStyleAlert];
   
  [alert addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleCancel handler:nil]];
   
  [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:alert animated:YES completion:nil];
   
  }
   
  }
   
  }
   
  }
   
  }];
   
  }
