prepareForSegue is not getting called when I click on a button without using performSegueWithIdentifier

Question

Based on the Stanford iOS course I am playing with modal view controllers. In the demo they have a button that would launch a modal view and when it is clicked the function prepareForSegue is called. I mimicked the code and implementation into my project with the only difference is that my demo is on an iPhone storyboard and theirs is on the iPad.

I noticed that while my modal view controller is coming up, it does not call prepareForSegue prior to that. I searched the Stanford project to see where they may register any segue behavior before prepareForSegue is called but there is no evidence. Can anyone shed some light on this. I searched stack overflow and all I found were that users were missing the call implementation of performSegueWithIdentifier. However, in the Stanford demo they never do that.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {     if ([segue.identifier hasPrefix:@"Create Label"]) {         AskerViewController *asker = (AskerViewController *)segue.destinationViewController;         asker.question = @"What do you want your label to say?";         asker.answer = @"Label Text";         asker.delegate = self;     }  } 

Here is an example of there storyboard:

Here is an example of my storyboard:

In the debugger when I stop in the Stanford Demo code the call stack shows that the storyboard is performing a segue action, what do I need to configure in my storyboard to achieve the same result?

Answer 1

Well, as it turns out, my view controller where button calls the modal view did not have the right class where prepareForSegue is implemented. It was the default UIViewController instead of my custom class.

The way I figured it out was by putting a break point in viewDidLoad and even that was not breaking and thus I suspected that in the storyboard I did not have the right class associated with the view where the button is implemented.
