Display and dismiss a modal view controller in Swift

问题

When a button is pressed I want to segue between two view controllers by using a Modal Transition style CoverVertical and then dismiss it. There is allot of info out there for how to do it in objective C but can't find any good info in Swift. So far I've done this but I don't think it's correct:

 @IBAction func insertStatus(sender: UIButton) {

         var StatusVC: StatusViewController = StatusViewController()
    var modalStyle: UIModalTransitionStyle = UIModalTransitionStyle.CoverVertical
    StatusVC.modalTransitionStyle = modalStyle
    self.presentViewController(StatusVC, animated: true, completion: nil)

    }

The Dismiss I am using like so does not work either:

@IBAction func statusSaved(sender: UIBarButtonItem) {

        self.dismissViewControllerAnimated(false, completion: { () -> Void in
            let usersVC: UsersViewController = self.storyboard?.instantiateViewControllerWithIdentifier("UsersViewController") as UsersViewController
       })
    }

Swift 5:

present(UIViewController(), animated: true, completion: nil)

dismiss(animated: true, completion: nil)

Swift 2.2:

self.presentViewController(true, completion: nil)

Hide/dismiss a view controller:

self.dismissViewControllerAnimated(true, completion: nil)

To Dismiss View Controller in Swift 3.0

self.dismiss(animated: true, completion: {})

You can use presentViewController:animated:completion: and dismissViewControllerAnimated:completion: methods from UIViewController. See docs here

Its pretty easy :

to dismiss a modal view with swift 3.0 : Use dismiss Api like below :

> @IBAction func dismissClick(_ sender: Any) {
>         dismiss(animated: true, completion: nil)
>         
>     }

For present :

> @IBAction func dismissClick(_ sender: Any) {
> present(UIViewController(), animated: true, completion: nil)
>         
>     }
