无法在Swift中关闭导航控制器 [英] Can't dismiss navigation controller in Swift

问题描述

因此，我有一个具有注册功能的简单导航控制器，点击完成，您就可以进入主页.问题是当您转到主页时，导航控制器随即出现.

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.

如您在最后一张图片(主页)中所看到的，导航栏保持不变.当用户在第一张图像上按完成"时，我使用self.performSegueWithIdentifier("loginTrue", sender: nil) 转到主页".我尝试使用

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)

但是似乎什么也没发生.因此，将其总结一下，关于如何从主页"退出"导航控制器的任何想法吗?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

尝试

self.navigationController?.popViewControllerAnimated(true)

更新:Swift 4.2

self.navigationController?.popViewController(animated: true)
