Swift / iOS。从导航堆栈中删除一些视图控制器 [英] Swift / iOS. Remove few view controllers from navigation stack

问题描述

这是我想做的事情，我不确定是否正确，所以请给我一个建议如何做。

Here is what I want to do and I am not sure is it right approach, so please give me an advise how to do it.

我有初始VC使用导航VC，从它推出第一个VC，从它推出第二个VC。

I have Initial VC with Navigation VC, from it I push First VC, from it I push Second VC.

接下来我出现（来自第二个VC的NavigationController）第三个VC。

Next I present (from NavigationController of Second VC) Third VC.

现在我想从导航堆栈中删除第一个和第二个VC。

And now I want to remove First and Second VCs from navigation stack.

之后我希望得到这样的结果：I解雇第三个VC，我看到初始VC

After that I expect to have such result: I dismiss Third VC and I see Initial VC

我怎样才能得到这个结果？

How can I get that result?

You can remove view controller from navigation stack by function:

navigationController?.viewControllers.removeAtIndex(*index of view controller you wanna remove*)
