swift peformSegue from child

I have a storyboard with a Navigation Controller hooked to 2 views, first one containing a UIScrollView which I have populated with several ViewController's (ex Home, Profile, etc), and a second one containing a login screen

I want to be able to logout from one of the subviews/childs of the UIScrollView, one way I've tried is

Simplified code snippet:

 ContainerViewController
    ViewdidLoad()
    {
        self.addChildViewController(BVc);
    }

ChildViewController containing a logout button

 ChildViewController
     @IBAction func Loggout(sender: AnyObject)
     {
         performSegueWithIdentifier("goto_login", sender: parent?)
     }

I hope I made myself clear, as It's my first post.

Solution

  • So, what you want to do is move back to earlier View Controller, am I right? If that's correct, you should access the View Controller's navigationController property. For example, if you want to go back in the navigation stack, you could pop the top view:

    navigationController?.popViewControllerAnimated(true)
