标题: ios - 当我的应用程序未激活时，PushNotification 角标(Badge)编号未显示？

我在我的应用程序中为 APNS 使用 Urbanairship，一切顺利，但当我的应用程序未运行时，应用程序角标(Badge)编号未显示，但是当应用程序处于事件状态并收到推送时，角标(Badge)编号显示在应用图标上方。

我的代码如下:

   - (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions
    {
     UAConfig *config = [UAConfig defaultConfig];
        [UAirship takeOff:config];
        // Request a custom set of notification types
        [UAPush shared].notificationTypes = (UIRemoteNotificationTypeBadge |
                                             UIRemoteNotificationTypeSound |
                                             UIRemoteNotificationTypeAlert |
                                             UIRemoteNotificationTypeNewsstandContentAvailability);

        return YES;
    }
    - (void)applicationUIApplication *)app didFailToRegisterForRemoteNotificationsWithErrorNSError *)err {

        NSString *str = [NSString stringWithFormat: @"Error: %@", err];
        NSLog(@"%@",str);

    }

    - (void)applicationUIApplication *)application didReceiveRemoteNotificationNSDictionary *)userInfo {
        NSLog(@"Received notification: %@", userInfo);
        //[self addMessageFromRemoteNotification:userInfo];

        NSString* alertValue = [[userInfo valueForKey"aps"] valueForKey"badge"];
        NSLog(@"my message-- %@",alertValue);
        int badgeValue= [alertValue intValue];

        [[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeValue];


    }
- (void)applicationDidBecomeActiveUIApplication *)application {

    application.applicationIconBadgeNumber = 0;
}

编辑:我也试过 -

- (void)applicationUIApplication *)application didReceiveRemoteNotificationNSDictionary *)userInfo {
    NSInteger badgeNumber = [application applicationIconBadgeNumber];
    [application setApplicationIconBadgeNumber:++badgeNumber];
}

但仍然没有运气，我做错了什么？

如果您还注册了 UIRemoteNotificationTypeNewsstandContentAvailability，则将其删除并重试。
