Ola Folks,

In an iPhone application I am displaying different views by using the addSubView:SomeViewController.view method.

I want to be able to, at the very least, log the view controllers that are in the view hierarchy that is being displayed. I would prefer to be able to get a handle to a specific view controller.

I know how to iterate the views, I just do not see how to access the view controllers of those views. I am looking for something that will give me the type of access to the view controllers that UINavigationController::ViewControllers does.

I thought I could get away with:

for (UIViewController* oVC in [self.view subviews])

but this is not having the intended effect.

If someone has a way of doing this, please share it with me.
