从iOS应用图标中删除徽章 [英] Removing badge from iOS app icon

问题描述

在我正在尝试制作的这个应用程序中，我使用推送通知。这部分工作正常。当我发送通知时，我还会在应用图标上添加徽章。问题是，当我在午餐时，应该会再次消失，但事实并非如此。

In this application that I'm trying to make, I use push notifications. This part works just fine. When I send a notification I also add a badge to the app icon. The problem is when I lunch the application it should disappear again, but it does not.

-(IBAction)Push{

    NSMutableDictionary *data = [NSMutableDictionary dictionary];

    [data setObject:@"Numfeud: Troels made a move!" forKey:@"alert"];

    [data setObject:[NSNumber numberWithInt:1] forKey:@"badge"];

    [data setObject:@"bar" forKey:@"foo"];

    [PFPush sendPushDataToChannelInBackground:@"GameChannel2" withData:data];
}

在应用程序中didFinishLaunchingWithOptions 我尝试以这种方式将徽章设置为0：

In the application didFinishLaunchingWithOptions I try to set badge to 0 in this way:

[UIApplication sharedApplication].applicationIconBadgeNumber = 0;

如何清除应用程序图标徽章？

推荐答案

如果您的应用再次变为活动状态但仍处于后台，则应重置 -applicationDidBecomeActive：中的徽章数量：

If your app becomes active again and is still in the background you should reset the badge count in -applicationDidBecomeActive: as well:

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    application.applicationIconBadgeNumber = 0;
}

如果您的应用仍然在后台运行 - application：didFinishLaunchingWithOptions：将不会被调用。

If your app is still running in the background -application:didFinishLaunchingWithOptions: won't be called.
