Question

I have a common UIViewController that all my UIViewsControllers extend to reuse some common operations.

I want to set up a segue on this “Common” UIViewController so that all the other UIViewControllers inherit.

I am trying to figure out how do I do that programmatically.

I guess that the question could also be how do I set a segue for all my UIViewControllers without going into the story board and do them by hand.

Answer 1

By definition a segue can’t really exist independently of a storyboard. It’s even there in the name of the class: UIStoryboardSegue. You don’t create segues programmatically – it is the storyboard runtime that creates them for you. You can normally call performSegueWithIdentifier: in your view controller’s code, but this relies on having a segue already set up in the storyboard to reference.

What I think you are asking though is how you can create a method in your common view controller (base class) that will transition to a new view controller, and will be inherited by all derived classes. You could do this by creating a method like this one to your base class view controller:

- (IBAction)pushMyNewViewController
{
    MyNewViewController *myNewVC = [[MyNewViewController alloc] init];

    // do any setup you need for myNewVC

    [self presentModalViewController:myNewVC animated:YES];
}

and then in your derived class, call that method when the appropriate button is clicked or table row is selected or whatever.
