How to remove a navigationController (iPhone)

My app has couple of normal views (V1, V2), without a navigationController, but when and ADD button is pushed creates a view with a navigationController like this:

CreateNewEventViewController.m

- (void)viewDidLoad {
    [super viewDidLoad];


    tableViewController = [[NewEventTableViewController alloc] init];

    navigationController = [[UINavigationController alloc] initWithRootViewController:tableViewController];
    tableViewController.navigationController.title = @"Add";

    [self.view addSubview:navigationController.view];
}

so the NewEventTableViewController is an UITableViewController. When done filling the data from the table, last cell is a button to save it and then go back to one of the main views (V1, V2).

NewEventTableViewController.m

V1 *myV1 = [[V1 alloc] init];
[self.view.superview addSubview:myV1.view];

but the navigationController I had stays. Any way of removing it?

update I've tried this, but all I get is a white screen. Also removing after adding the new view. (this code is placed in NewEventTableViewController)

[self.navigationController.view remove开发者_StackOverflow中文版FromSuperview];
    V1 *myV1 = [[V1 alloc] init];
    [self.view addSubview:myV1.view];

update 2 Is not what I really needed but anyway I can use this.

[self.navigationController.view.superview removeFromSuperview];

it removes the navigationController and it's table view and it displays the view I had before I call the CreateNewEventViewController.

Not much sure why you wanna do that, but there is a possibility to hide navigationController

self.navigationController.navigationBarHidden = YES;
