Question

I know that I can use popToRootViewController if I have navigationController in my project but my whole project is based on presentViewControllers and there is a scenario where I am navigating to multiple levels. If there is only one level I can get back to root view controller by dismissing current view controller but I am not able to figure out how to navigate back to root view controller when I am down to more than one level. Could someone please advice me here?

I tried to use following code but my App crashes!

- (IBAction)mainMenuButtonPressed:(id)sender {
    MyAppDelegate *delegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
    [self presentModalViewController:delegate.window.rootViewController animated:YES];
}

Thanks.

If I understood you right then you are presenting several modal viewcontrollers and want to get back to the root viewcontroller. If that’s right then the following code should work for you:

- (IBAction)mainMenuButtonPressed:(id)sender {
    MyAppDelegate *delegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
    [delegate.window.rootViewController dismissModalViewControllerAnimated:YES];
}
