Programmatically get a Storyboard ID?

Trying to see if a UIViewController or UIView can identify its Storyboard ID. So was hoping for:

UIViewController *aViewController;
NSString *storyboardID = aViewController.storyboard.id;  //not an actual property

or:

NSString *storyboardID = [aViewController.storyboard valueForKey:@"storyboardId"];  //also not a working call

But no joy and couldn't find a similar solution online. Does anyone know if this is even possible?

You can use the restorationIdentifier, it's right above the Storyboard identifier and it's a UIViewController property.

You can use the Restoration ID:

NSString *restorationId = self.restorationIdentifier;

Just check the checkbox 'Use Storyboard ID'

The storyboard id is only meant to find and instantiate a VC from a storyboard. As written in the UIStoryboard reference:

"This identifier is not a property of the view controller object itself and is only used by the storyboard file to locate the view controller."

Why do you need it?

You can also try doing something like this:-

NSString *storyboardId = [viewController valueForKey:@"storyboardIdentifier"];

This will precisely give you the Storyboard Id that you have set via interface builder.

Swift extension:

extension UIViewController {
    var storyboardId: String { 
        return value(forKey: "storyboardIdentifier") as? String
    }
}

The most reliable method for returning the "id" of the UIViewController or UIView is...

NSString *viewControllerName = [[NSString alloc] initWithString:viewController.nibName];

This will return... "29w-Ic-LNo-view-FDu-oq-UpZ", where "29w-Ic-LNo" is the Object ID of the UIViewController and "FDu-oq-UpZ" is the Object ID of the UIView.

However, you may also use...

NSString *viewControllerName = [[NSString alloc] initWithString:viewController.title];

This will return the "Title" of the UIViewController in the Attributes Inspector; so just as easily as you added the Storyboard ID to the UIViewController, you may also add a title.

You can compare with class name . import class and then try.

NSArray *viewControllers = self.navigationController.viewControllers;
UIViewController *root = [viewControllers objectAtIndex:0];
if ([root isKindOfClass:[UserLogin class]]) {
//--- do ---
}
