iOS Xcode 4.2 using StoryBoard to present a ViewController

The new way of presenting a viewcontroller using the StoryBoard.

    UIStoryboard* secondStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

UINavigationController* secondViewController = [secondStoryboard instantiateViewControllerWithIdentifier:@"Connect"];

[self presentViewController: secondViewController animated:YES completion: NULL];

The old way of presenting the controller Connect is like this

  Connect *connect = [[[Connect alloc] initWithNibName:@"Connect" bundle:nil] autorelease]; 

[self presentViewController:connect animated:YES completion:NULL];
 NSString *userid;
 userid=@"123";

 [connect setID:userid];

I want to call the setID function of the connect controller in the Storyboard way, how can I do that? Seems like I don't get an instance of Connect controller directly.

You should subclass the view controllers so that you can control what happens when users interact with it (unless your app can function on segues alone.)

In Xcode, File -> New -> File -> Cocoa Touch Class. Make a class like MyAwesomeViewController that subclasses (in your case) UINavigationController.

I like to make a custom method called NewVC in my custom view controller classes. It can do everything you list above, plus any custom setup:

+(MyAwesomeViewController *)NewVC {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName: @"MyStoryboard" bundle: nil];
    return [storyboard instantiateViewControllerWithIdentifier: @"MyAwesomeViewController"];
}

This way when you want to create a new one you can just call [MyAwesomeViewController NewVC] and it'll return a new view controller instance.

Why are you casting it as UINavigationController? Just do what you were doing.

Connect* connect = [secondStoryboard instantiateViewControllerWithIdentifier:@"Connect"];
