Using Storyboard instead of Nib

Question

I'm trying to recreate a small iOS app that utilized nib files. I'm trying to replace the following line of code

 self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];

with:

UIStoryboard*  sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController* viewController = [sb instantiateViewControllerWithIdentifier:@"viewController"];    self.window.rootViewController = self.    viewController;

I'm getting the following error: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Storyboard () doesn't contain a view controller with identifier 'viewController''

I got the latter code from a previous Stack Overflow question on a similar topic. Can someone please advise on what the issue I'm having is and how to proceed?

Answer 1

You need to name the view controller in your storyboard by giving it a storyboard id. I typically try to use something memorable like the name of the view controllers class so I don't have to look it up.
