I have a custom ViewController that is meant to be reusable, and an arbitrary number of instances will be chained together in a NavigationController in Storyboard, all sharing the same model as a delegate.

The ViewControllers need to tell the model which instance they are. Currently, they have an int property that they get from the segue, but it doesn’t seem very idiomatic and doesn’t lend itself to having multiple instances onscreen (for iPad). I figure there’s got to be a cleaner way to do this, so does anyone know what it is? Thanks.

RESULT: self.view.tag

    A UIViewController’s UIView has a tag property which you can set from anywhere you want. You could also simply identify the type of the controller by using [self class]. Or simply use the memory location by referencing the controller directly.

    Update You could simply implement a unique identifier for a UIViewController using a category.
