尝试标记应用程序图标但尚未获得用户的许可以标记应用程序

Question

我正在使用iOS 8和Xcode 6.我encountered Attempting to badge the application icon problem，我在app delegate中设置了步骤。

我错过了什么吗？

代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
[self registerRemoteNotification];
...
}

- (void)registerRemoteNotification
{
#ifdef __IPHONE_8_0
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {

        UIUserNotificationSettings *uns = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound) categories:nil];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
        [[UIApplication sharedApplication] registerUserNotificationSettings:uns];
    } else {
        UIRemoteNotificationType apn_type = (UIRemoteNotificationType)(UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeSound|UIRemoteNotificationTypeBadge);
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:apn_type];
    }
#else
    UIRemoteNotificationType apn_type = (UIRemoteNotificationType)(UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeSound|UIRemoteNotificationTypeBadge);
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:apn_type];
#endif
}
