Hi,

In my application, I am having following UIViewControllers;


HomeViewController
FirstViewController
SecondViewController, and etc...

My question is; How can I find out whether SecondViewController is a current UIViewController or not ?

GoodQuestion

I use the Application Delegate with one reference for all my controllers and a variable called currentController that i set when there is a change of controller.

If your app is based on a navigation controller, the navigation controller includes properties that give you what you want.


viewControllers gives you an array of all the view controllers on the view controller "stack" (the front view controller and any view controllers that are covered by the front view controller, down to the root view controller.)

visibleViewController gives you a pointer to the current frontmost view controller.

I have find out the solution. Here is the code;

if([[self.navigationController visibleViewController] isKindOfClass:[SecondViewController class]])
{
}
else{
}
