Question

Just a simple question

Currently i present a modal view like this:

+ (void)showModalController:(id)ContentController InViewController:(UIViewController*)vc withFrame:(CGRect)rect{

UINavigationController *modalViewNavController = [[UINavigationController alloc] initWithRootViewController:ContentController];
modalViewNavController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
modalViewNavController.modalPresentationStyle = UIModalPresentationFormSheet;

[vc presentModalViewController:modalViewNavController animated:YES];

//it's important to do this after presentModalViewController
modalViewNavController.view.superview.frame = rect;

//self.view assumes the base view is doing the launching, if not you might need self.view.superview.center etc.
modalViewNavController.view.superview.center = vc.view.center;

[modalViewNavController release];

}

I pass the values of the UIViewController Content that it will be presented, at a custom modal size. I also pass the values of the UIViewController where the modal it will be presented.

In terms of code, i want to know the “vc” name at the content class, if it’s possible to do so.

EDIT

Lets say i have 2 classes, one is called DetailViewController where the modal will be presented. And the other one is called ModalContentViewController.

I want to know at the ModalContentViewController class (when the view appears, or is loaded) the name of the DetailViewController.

Any ideas?

PD: Currently Using…

Look for the UIViewController property presentingViewController. Here’s a quote from the docs:

If the view controller that received this message is presented by
another view controller, this property holds the view controller that
is presenting it. If the view controller is not presented, but one of
its ancestors is being presented, this property holds the view
controller presenting the nearest ancestor. If neither the view
controller nor any of its ancestors are being presented, this property
holds nil.

So you could use that property to get the presenting VC’s name.
