You can use delegate.

Set the object that created your new view controller as delegate. When you presenting your view controller add it to navigation bar. Setup your view controller with cancel/done buttons and set them up to pass the messages to delegate.

When user selects cancel/done the delegate method is called. Delegate can then dismiss the view controller.

See the example in View Controller programming guide for iPhone OS.

You'll have to setup the buttons and call to delegate when you create your view controller.

If you have used "present model view controller"

then you required to use "dismis model view controller" instead of using "pop view controller" for going back...
