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) {                             
  }];
[application registerForRemoteNotifications];

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");        
}       
}];

• 本地通知：

// 创建一个距离现在时间 多久之后的触发的本地通知 
 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     repeats 是否重复  
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);
    }];

• iOS 10之前的重复设置是repeatInterval 属性,可以按年、月、日、星期等规律设置重复时间，例如：

    NSCalendarUnitWeekday
    NSCalendarUnitWeekOfMonth
    NSCalendarUnitDay
    NSCalendarUnitMonth

• iOS 10之后repeatInterval设置：

triggerWithRegion:repeats:
triggerWithTimeInterval:repeats:
triggerWithDateMatchingComponents:repeats:

说明：repeats 是布尔类型，无法设置重复类型；其实他是根据你传入的值确定下一次触发的时间，例如：

        NSCalendar *calendar = [NSCalendar currentCalendar];
        calendar.locale = [[NSLocale alloc]initWithLocaleIdentifier:@"zh_CN"];
        NSDateComponents* comps = [[NSDateComponents alloc] init];
        NSInteger unitFlags =NSCalendarUnitWeekday|
        NSCalendarUnitHour |NSCalendarUnitMinute |NSCalendarUnitSecond ;
        comps = [calendar components:unitFlags fromDate:time];
        UNCalendarNotificationTrigger *trigger_1 = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:comps repeats:YES];

**注意** 如果你希望是按星期重复NSCalendarUnit 就设置NSCalendarUnitWeekday；如果按月重复设置NSCalendarUnitDay；如果同时出现NSCalendarUnitWeekday、NSCalendarUnitYear、NSCalendarUnitMonth、NSCalendarUnitDay下一次的触发时间就会混乱 无规律可寻；

• 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) {       
    }];

• 处理通知：
  设置UNUserNotificationCenterDelegate：
  注意：UNUserNotificationCenter 的 delegate 必须在 application:willFinishLaunchingWithOptions:
  or application: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];
                            }
                } 
           }
        }
 }];
}
