objective-c - 本地通知，当应用程序处于前台时，applicationIconBadgeNumber保留

Question

当应用程序处于前台时，即使我将applicationBadgeNumber设置为0，当我退出该应用程序时，我的应用程序上仍然有一个“1”徽章，哪怕我杀死了它，有什么想法吗？当我在后台运行应用程序时打开通知时，完全没有问题!

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification 
    {   
        NSLog(@"%i", notification.applicationIconBadgeNumber); // Return 1
        notification.applicationIconBadgeNumber = 0;
        NSLog(@"%i", notification.applicationIconBadgeNumber); // Return 0

        UIApplicationState state = [application applicationState];

        if (state == UIApplicationStateInactive)
        {
            // Application was in the background when notification
            // was delivered.
        }
        else
        {
            UIAlertView *alert = [[UIAlertView alloc]
                                  initWithTitle:@"An item is asking your attention" message:nil delegate:nil
                                  cancelButtonTitle:@"Cancel" otherButtonTitles:@"Show me", nil];
            [alert show];
        }
    }

您在哪里设置applicationBadgeNumber？我认为您正在设置通知徽章编号。

试试这个:

 application.applicationIconBadgeNumber = 0;
