@[@“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:UNNotificationCategoryOptionCustom
