How do I Access an Already Existing View Controller

I want to move from one view controller to the next, using code. I have this:

[self.navigationController pushViewController:ViewController2 animated:YES];

This code is used in the first screen that launches. I want it to push (under a certain condition) to the NEXT view controller which is called ViewController2. ViewController2 already exists (its a storyboard project). But the current view controller doesn't know what ViewController2 is in the above code. How do I 'get' or 'access' ViewController2? It already exits, with .h and .m files, but how do I call to it!?

if you're using storyboards, you can just access it through its identifier like this:

ViewController2 *viewController2 = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewController2"];

Make sure to properly set its identifier to "ViewController2" or whatever name makes sense.

This isn't the way that you normally push a view controller when you're using storyboards. You should have a push segue set up in IB and the use performSegueWithIndentifier:sender: to go to the next controller. You should also implement prepareForSegue:sender: where you can get access to both the source and destination controllers. This is the method where you typically provide any data needed for the second view controller to do its job.
