Swift 4 以编程方式定位元素

Question

我在将灰色弹出窗口放置在屏幕顶部时遇到问题。它有 x 和 y = 0.0

override func viewDidLoad() {
    let dialogheigth:CGFloat = self.view.frame.height;
    let dialogwidth:CGFloat = self.view.frame.width;
    self.preferredContentSize = CGSizeMake(dialogwidth,dialogheigth);
}

我用的人https://github.com/daisuke310vvv/PopupController库作为弹出窗口我的解决方案是将正确 ViewController 发送到 PopUp

let popup = PopupController.create(YourViewController).didShowHandler { popup in
   // Do something
}
.didCloseHandler { _ in
   // Do something
}
