iPhone - dismiss multiple ViewControllers

Question

I have a long View Controllers hierarchy;

in the first View Controller I use this code:

SecondViewController *svc = [[SecondViewController alloc] i         


        

Answer 1

Apple document about dismiss(animated:completion:) method.

In section Discussion, it said:

any intermediate view controllers are simply removed from the stack.

If you present several view controllers in succession, thus building a stack of presented view controllers, calling this method on a view controller lower in the stack dismisses its immediate child view controller and all view controllers above that child on the stack. When this happens, only the top-most view is dismissed in an animated fashion; any intermediate view controllers are simply removed from the stack. The top-most view is dismissed using its modal transition style, which may differ from the styles used by other view controllers lower in the stack.

In other words, if the view controller stack like following

Root -> A -> B -> C -> D ... -> Z

D calls dismiss method, all view controllers behide D, ex: (E ... Z), will be removed from the stack.
