swift - 在表格 View 单元格中显示弹出窗口

Question

我想在 Tableview 单元格 ViewController 中呈现一个弹出窗口。我想要这个，因为在 TableViewCell 中有一个按钮，按下时需要弹出。请帮我!如果我运行这个，我会收到错误:

InstagramClone.SignInViewController: 0x102e22b30 whose view is not in the window hierarchy!

@objc func kik (){
        if let Kik = user?.KikUsername {
            // Prepare the popup assets
            let title = "Kik Username"
            let message = "The Kik username from \(user?.username) is: \(Kik)."
            let image = UIImage(named: "kik-icon.jpg")

            // Create the dialog
            let popup = PopupDialog(title: title, message: message, image: image)

            // Create buttons
            let buttonOne = CancelButton(title: "Cancel") {
                print("You canceled")
            }

            // This button will not the dismiss the dialog
            let buttonTwo = DefaultButton(title: "Copy Kik Username to clipboard!", dismissOnTap: false) {
                UIPasteboard.general.string = Kik
            }
            popup.addButtons([buttonOne, buttonTwo])

            // Present dialog
            self.window?.rootViewController?.present(popup, animated: true, completion: nil)
        }

    }

我认为您只需将弹出窗口添加到主视图:

self.view.addSubview(popup)
