如何在故事板中为视图控制器提供“标识符”？

Question

The instantiateViewControllerWithIdentifier: method requires that the view controller I pass have an identifier. I went to my storyboard and clicked on my view controller, but I see no option to set the identifier. Where exactly do I find this option?

Answer 3

In the identity inspector there is a field Storyboard ID . You could enter the class name here and then use this identifier in instantiateViewControllerWithIdentifier: .
