ios - 收到远程通知时是否有对应用程序委托(delegate)的回调？

Question

收到远程通知并且用户采取操作(关闭/关闭除外)后，应用程序委托(delegate)将获取回调:

-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

或者如果应用程序注册了通知操作:

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

我的问题是，当收到远程通知时，应用程序是否会得到回调？那是在用户采取任何操作之前。感谢您的投入。

extension AppDelegate: UNUserNotificationCenterDelegate {

    public func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler([.alert,.sound,.badge])
        print("NOtification received")
    }

    public func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    print("original body was : \(response.notification.request.content.title)")
    print("Tapped in notification")

    }
}
