Dismissing multiple modal views

My application presents a modal view (A) from the main view that lets the user make a selection. When they make that selection it opens a second modal view (B) on top of the first one (A).

When I'm done with the second modal view (B), and want to dismiss it, I would like to dismiss the first one (A) and the second one (B) at the same time as I no longer need the user to return 开发者_Go百科to that one (A) either.

The only thing I came up with is:

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

It works, but it just doesn't look correct. Is this OK to do or is there a more accepted way to do this?

I don't think that your way is wrong. It is what Apple documentation recommends:

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.

(UIApplication.sharedApplication().delegate! as! AppDelegate).navigationController?.viewControllers.first?.dismissViewControllerAnimated(true, completion: nil)
