应用程序UIUserNotificationSettings不起作用

Question

更新我的应用程序，并首次在iOS 8.0问题中弃用。需要帮助解决以下代码才能与iOS 12.2一起使用

if([[UIDevice currentDevice] systemVersion].floatValue >= 8.0)
{
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
}
else
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound|UIRemoteNotificationTypeBadge)];
}


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


- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings


- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
