收到推送通知时清除徽章

发布于 2024-11-03 19:29:41 字数 66 浏览 1 评论 0原文

当我收到推送通知时，如何清除应用程序图标上出现的徽章？我想在用户点击推送通知警报的“查看”或点击应用程序图标后清除它。

我怀疑你在谈论 SpringBoard 的徽章：

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]

I suspect you are talking about the SpringBoard's badge:

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]

Badge count set Zero

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]

使用此代码取消所有本地通知：

[[UIApplication sharedApplication] cancelAllLocalNotifications];

使用此行代码取消一个本地通知：

[[UIApplication sharedApplication] cancelLocalNotification:theNotification];

这里 theNotification 是一个 UILocalNotification 对象，因此为了取消特定通知，您需要保留它的 UILocalNotification。

检查此。

Badge count set Zero

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]

Cancel all local notifications with this code:

[[UIApplication sharedApplication] cancelAllLocalNotifications];

Cancel one local notification with this line of code:

[[UIApplication sharedApplication] cancelLocalNotification:theNotification];

here theNotification is a UILocalNotification object, so in order to cancel a specific notification, you need to hold on to it's UILocalNotification.

Check this.

对于 Mac OS X Lion，它是：

    [NSApp dockTile].badgeLabel = @"";

（Lion 支持徽章类型推送通知。）

For Mac OS X Lion, it's:

    [NSApp dockTile].badgeLabel = @"";

(Lion supports badge-type push notifications.)

根据 Apple 文档，将 application.applicationIconBadgeNumber 设置为您想要在徽章上显示的数字。如果设置为0，则会被清除。

- (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

    if (localNotif) {
        NSString *itemName = [localNotif.userInfo objectForKey:ToDoItemKey];
        [viewController displayItem:itemName];  // custom method
        application.applicationIconBadgeNumber = localNotif.applicationIconBadgeNumber-1;
    }

    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
    return YES;
}

参考 - 向下滚动到处理清单 2.4 上方的本地和远程通知部分

From Apple's documentation, set the application.applicationIconBadgeNumber to the number you want displayed on the badge. If you set it to 0, it will be cleared.

- (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

    if (localNotif) {
        NSString *itemName = [localNotif.userInfo objectForKey:ToDoItemKey];
        [viewController displayItem:itemName];  // custom method
        application.applicationIconBadgeNumber = localNotif.applicationIconBadgeNumber-1;
    }

    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
    return YES;
}

Reference - Scroll down to the Handling Local and Remote Notifications section just above listing 2.4
