Question

I have a long View Controllers hierarchy;

in the first View Controller I use this code:

SecondViewController *svc = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
[self presentModalViewController:svc animated:YES];    
[svc release];

In the second View Controller I use this code:

ThirdViewController *tvc = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
[self presentModalViewController:tvc animated:YES];    
[tvc release];

and so on.

So there is a moment when I have many View Controllers and I need to come back to the first View Controller.
If I come back one step at once, I use in every View Controller this code:

[self dismissModalViewControllerAnimated:YES];

If I want to go back directly from the, say, sixth View Controller to the first one, what I have to do to dismiss all the Controllers at once?

Thanks

I found the solution.

Of course you can find the solution in the most obvious place so reading from the UIViewController reference for the dismissModalViewControllerAnimated method …

If you present several modal view
controllers in succession, and thus
build a stack of modal 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.

so it’s enough to call the dismissModalViewControllerAnimated on the target View.
I used the following code:

[[[[[self parentViewController] parentViewController] parentViewController] parentViewController] dismissModalViewControllerAnimated:YES];

to go back to my home.
