不能在 Swift 中关闭导航控制器

问题描述

所以我有一个简单的导航控制器，带有一个注册，点击完成，然后你转到主页.问题是当您转到主页时，导航控制器随之而来.

So I have a simple navigation controller with a sign up, hit done and you go to the home page. The problem is when you go to the home page, the navigation controller follows.

正如您在最后一张图片(主页)中看到的那样，导航栏仍然存在.当用户在第一张图片上按下完成"时，我使用 self.performSegueWithIdentifier("loginTrue", sender: nil) 转到主页".我试过使用

As you can see in the last picture (home page), the navigation bar remains. When the user presses "Done" on the first image I use self.performSegueWithIdentifier("loginTrue", sender: nil) to go to the "home page". I've tried using

self.presentingViewController?.dismissViewControllerAnimated(true, completion: nil)

但似乎什么也没发生.所以总结一下，关于如何从主页"关闭"导航控制器的任何想法?谢谢！

But nothing seems to happen. So to wrap it all up, any idea on how I can "dismiss" the navigation controller from the "home page"? Thanks!

推荐答案

试试

self.navigationController?.popViewControllerAnimated(true)

更新:Swift 4.2

self.navigationController?.popViewController(animated: true)
