Display and dismiss a modal view controller in Swift
提问by Cesare
When a button is pressed I want to segue between two view controllers by using a Modal Transition style CoverVerticaland 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:
当按下按钮时，我想通过使用模态转换样式在两个视图控制器之间进行切换CoverVertical，然后关闭它。有很多关于如何在目标 C 中做到这一点的信息，但在 Swift 中找不到任何好的信息。到目前为止，我已经这样做了，但我认为这是不正确的：
@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:
我正在使用的 Dismiss 也不起作用：
@IBAction func statusSaved(sender: UIBarButtonItem) {
self.dismissViewControllerAnimated(false, completion: { () -> Void in
let usersVC: UsersViewController = self.storyboard?.instantiateViewControllerWithIdentifier("UsersViewController") as UsersViewController
})
}
