更新徽章的图标，当应用程序被关闭 [英] Update badge icon when app is closed

问题描述

我试图更新我的应用程序徽章图标（关闭）时，我收到一个PN。

我曾尝试加入codeS进入，但是当我的应用程序关闭时它不工作。当应用程序在前台运行它的工作原理。

   - （BOOL）应用：（*的UIApplication）的应用didFinishLaunchingWithOptions：（NSDictionary的*）launchOptions
{
       *的NSDictionary = remoteNotif [launchOptions objectForKey：UIApplicationLaunchOptionsRemoteNotificationKey];//接受推送通知的应用程序时未打开
    如果（remoteNotif）{
      [应用setApplicationIconBadgeNumber：100];
    返回YES;
    }}
     - （无效）应用：（*的UIApplication）的应用didReceiveRemoteNotification：（NSDictionary的*）USERINFO
    {            [UIApplication的sharedApplication] setApplicationIconBadgeNumber：30];    }
 

解决方案

如果您的应用程序被关闭或在后台推送通知不会唤醒它。你需要做服务器端，包括你想看到的图标在您的通知有效载荷数：

  {
    APS：{
        提醒：您的通知消息，
        徽章：1
    }
}

I am trying to update the badge icon for my app(closed) when I received a PN.

I have tried adding the codes into but it's not working when my app is closed. It works when the app is running in the foreground.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
       NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];

//Accept push notification when app is not open
    if (remoteNotif) {
      [application setApplicationIconBadgeNumber:100];
    return YES;
    }

}
    -(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
    {

            [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 30];

    }

解决方案

If you app is closed or in the background, a Push notification won't wake it up. You need to do this server side and include the number you want to see on icon in your notification payload:

{
    "aps" : {
        "alert" : "Your notification message",
        "badge" : 1
    }
}

Have a look at the Apple doc on Push Notification programming guide
