如何关闭以模态显示的UINavigationController？

Question

I have the following structure:

UINavigationController(1) -> MainViewController     ---PRESENT MODAL---> 
UINavigationController(2) -> TutorialViewController ---PRESENT MODAL---> LoginViewController
                                                    ---PRESENT MODAL---> SignupViewController

I want to dismiss the UINavigationController(2) from a user action on LoginViewController.

Any idea?

You should use delegation to dismiss the second view controller. So you would have the second nav controller be dismissed by the first nav controller, the one that presented it. This is the recommended way to dismiss modal views.

Here are the docs on delegation
