[置頂] iOS10--消息通知的基本使用

官方將通知單獨(dú)放在了UserNotifications.framework，使用時(shí)需要導(dǎo)入框架。
UserNotifications.framework主要類(lèi)文件：

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

UNUserNotificationCenter的利用：

• 要求用戶(hù)授權(quán)：
  UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter]; // 要求授權(quán) /* UNAuthorizationOptionBadge = (1 << 0), UNAuthorizationOptionSound = (1 << 1), UNAuthorizationOptionAlert = (1 << 2), UNAuthorizationOptionCarPlay = (1 << 3), */ [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) { }];
  補(bǔ)充：獲得授權(quán)設(shè)置信息
  // 獲得通知授權(quán)和設(shè)置 [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) { /* UNAuthorizationStatusNotDetermined : 沒(méi)有做出選擇 UNAuthorizationStatusDenied : 用戶(hù)未授權(quán) UNAuthorizationStatusAuthorized ：用戶(hù)已授權(quán) */ if (settings.authorizationStatus == UNAuthorizationStatusNotDetermined) { NSLog(@"未選擇"); }else if (settings.authorizationStatus == UNAuthorizationStatusDenied){ NSLog(@"未授權(quán)"); }else if (settings.authorizationStatus == UNAuthorizationStatusAuthorized){ NSLog(@"已授權(quán)"); } }];

• 創(chuàng)建本地通知：

  // 創(chuàng)建1個(gè)本地通知 UNMutableNotificationContent *content_1 = [[UNMutableNotificationContent alloc] init]; // 主標(biāo)題 content_1.title = [NSString localizedUserNotificationStringForKey:@"title" arguments:nil]; // 副標(biāo)題 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]; // 設(shè)置觸發(fā)時(shí)間 UNTimeIntervalNotificationTrigger *trigger_1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO]; // 創(chuàng)建1個(gè)發(fā)送要求 UNNotificationRequest *request_1 = [UNNotificationRequest requestWithIdentifier:@"my_notification" content:content_1 trigger:trigger_1];

  補(bǔ)充：

  • UserNotifications提供了3種觸發(fā)器：
    UNTimeIntervalNotificationTrigger ：1定時(shí)間后觸發(fā) UNCalendarNotificationTrigger ： 在某月某日某時(shí)觸發(fā) UNLocationNotificationTrigger ： 在用戶(hù)進(jìn)入或是離開(kāi)某個(gè)區(qū)域時(shí)觸發(fā)
  • @“my_notification”要求的標(biāo)識(shí)符可以用來(lái)管理通知：
    - 移除還未展現(xiàn)的通知 [center removePendingNotificationRequestsWithIdentifiers: @[@“my_notification” ]]; [center removeAllPendingNotificationRequests]; // - (void)cancelAllLocalNotifications； - 移除已展現(xiàn)過(guò)的通知 [center removeDeliveredNotificationsWithIdentifiers:@[@“my_notification” ]]; [center removeAllDeliveredNotifications]; - 獲得未展現(xiàn)的通知 [center getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) { NSLog(@"%@",requests); }]; - 獲得展現(xiàn)過(guò)的通知 [center getDeliveredNotificationsWithCompletionHandler:^(NSArray<UNNotification *> * _Nonnull notifications) { NSLog(@"%@",notifications); }];
  • 遠(yuǎn)程通知的格式：
    { "aps":{ "alert":{ "title":"I am title", "subtitle":"I am subtitle", "body":"I am body" }, "sound":"default", "badge":1 } }
    具體請(qǐng)參考官方文檔

• 將通知要求添加到通知中心（UNUserNotificationCenter）：

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

接收通知

• 處理通知：
  設(shè)置UNUserNotificationCenterDelegate：
  注意：UNUserNotificationCenter 的 delegate 必須在 application:willFinishLaunchingWithOptions: or application:didFinishLaunchingWithOptions: 方法中實(shí)現(xiàn)；

  center.delegate = self;

  • 利用內(nèi)展現(xiàn)通知:

    - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{ // 如果不想顯示某個(gè)通知，可以直接用空 options 調(diào)用 completionHandler: // completionHandler([]) completionHandler(UNNotificationPresentationOptionBadge + UNNotificationPresentationOptionSound); }
  • 在用戶(hù)與你推送的通知進(jìn)行交互時(shí)被調(diào)用：
    - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{ completionHandler(); NSLog(@"userInfo--%@",response.notification.request.content.userInfo); }

UNNotificationCategory的利用：

• 創(chuàng)建1個(gè) category：
  /* UNNotificationActionOptionAuthenticationRequired = (1 << 0), UNNotificationActionOptionDestructive = (1 << 1), 取消 UNNotificationActionOptionForeground = (1 << 2), 啟動(dòng)程序 */ UNTextInputNotificationAction *textAction = [UNTextInputNotificationAction actionWithIdentifier:@"my_text" title:@"text_action" options:UNNotificationActionOptionForeground textInputButtonTitle:@"輸入" textInputPlaceholder:@"默許文字"]; 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];
• 在創(chuàng)建 UNNotificationContent 時(shí)把 categoryIdentifier 設(shè)置為需要的 category id 便可：
  content.categoryIdentifier = @"my_category";

  遠(yuǎn)程推送也能夠使用 category，只需要在 payload 中添加 category 字段，并指定預(yù)先定義的 category id 就能夠了

• 處理category的通知：
  - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{ completionHandler(); NSLog(@"userInfo--%@",response.notification.request.content.userInfo); // 獲得通知中心的所有的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:@"肯定" style:UIAlertActionStyleCancel handler:nil]]; [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:alert animated:YES completion:nil]; } } } } }]; }
