I try to call the main ViewController on my storyboard. In my app there is a additional .h, .m file with no xib or storyboard.

In this .m file T craeted a button:

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:@selector(home:)forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[self.view addSubview:button];
NSLog(@"Home-Button line 645");

This button should link to my main ViewController in the Storyboard. The view has the identifier HauptMenu. I got no error, but the view doesnt change to my main ViewController. What is wrong?

    - (IBAction)home:(id)sender {
    NSLog(@"Button was tapped");
    ViewController *viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"HauptMenu"];

    NSLog(@"1");
    [viewController setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
    NSLog(@"2");
    [self.navigationController pushViewController:viewController animated:NO];
    [viewController release];
    NSLog(@"3");

}
