在Swift中显示和关闭模式视图控制器 [英] Display and dismiss a modal view controller in Swift

问题描述

当按下一个按钮时，我想使用模态过渡样式CoverVertical在两个视图控制器之间进行筛选，然后将其关闭.关于如何在目标C中执行操作的信息很多，但是在Swift中找不到任何好的信息.到目前为止，我已经做到了，但是我认为这是不正确的:

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)

    }

我正在使用的Dismiss也不起作用:

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
       })
    }

推荐答案

Swift 5:

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

dismiss(animated: true, completion: nil)

Swift 2.2:

Swift 2.2:

self.presentViewController(true, completion: nil)

隐藏/关闭视图控制器:

self.dismissViewControllerAnimated(true, completion: nil)
