问题
I am trying to leave the initial view controller, and go into the blank view controller. That is fine, but that would make the blank view controller also part of the navigation controller, which is not what I want. I want to segue out of the view controller.
In the view controller I try to segue out of, it pops it self, and when I try the method in the view will appear of the target view controller, self.navigationController?.topViewController returns itself, but self.navigationController?.popViewControllerAnimated(animated) doesn't work
回答1:
If you have a navigationController do
self.navigationController?.popViewControllerAnimated(false)
Otherwise do
self.dismissViewControllerAnimated(false, completion: nil)
Update
Go to your Storyboard, select the ViewController you want to navigate to and add a storyboard id. Make sure the click "Use Storyboard ID"
Go to the class you want to navigate from and add the following code
let storyboard = UIStoryboard(name: "Main", bundle: nil)
// vc is the Storyboard ID that you added
// as! ... Add your ViewController class name that you want to navigate to
let controller = storyboard.instantiateViewControllerWithIdentifier("vc") as! ViewController
self.presentViewController(controller, animated: true, completion: { () -> Void in
})
Add this code in the action that you use when you want to navigate.

I believe this can be done without having to write any code at all. To Segue out of a Navigation Controller follow these steps:
- Create a Segue from the View Controller that has a Navigation Controller as it's root view controller to the View Controller that you would like to go to next (without being inside the Navigation Controller)
- Click on the new Seque
- Open the Attributes Inspector
- Choose 'Kind' -> 'Present Modally'
- Choose 'Present' -> 'Over Current Context'
