如何在 xcode 4 中以编程方式创建弹出视图？我正在尝试创建一个弹出视图，其中有一个网络视图，我在视图中添加一个后退按钮。我想转到上一个视图，按下后退按钮时将调用该视图。我该怎么做？

步骤1 - 在storyboard中创建新的VC，在VC中创建新的UIView。将其命名为 (ViewPopupUI)，然后在 ViewPopupUI 中声明所需的字段和属性。

第 2 步 - VC 内部

@IBOutlet private weak var viewPopupUI:UIView!
@IBOutlet var btnClose: UIButton!

override func viewDidLoad() {
    super.viewDidLoad()

   self.showViewWithAnimation()
}

@IBAction func btnCloseAction(_ sender: Any) {

    self.hideViewWithAnimation()
}

 //MARK: - Animation Method
private func showViewWithAnimation() {

    self.view.alpha = 0
    self.viewPopupUI.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)

    UIView.animate(withDuration: 0.3) {
        self.viewPopupUI.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)
        self.view.alpha = 1
    }
}

private func hideViewWithAnimation() {

    UIView.animate(withDuration: 0.3, animations: {

        self.viewPopupUI.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)
        self.view.alpha = 0

    }, completion: {
        (value: Bool) in

        self.removeFromParent()
        self.view.removeFromSuperview()
    })
}

调用弹出窗口

let popupVC = storyboard?.instantiateViewController(withIdentifier: "SchoolEventGoingPopup_VC") as! SchoolEventGoingPopup_VC
    popupVC.strId =  self.dictEventDetails?.object(forKey: "id") as? Int
    view.addSubview(popupVC.view)
    addChildViewController(popupVC)

Step:1 - In storyboard create new VC, create new UIView inside VC. name it (ViewPopupUI) and then declare fields and properties you want inside ViewPopupUI.

Step:2 - Inside VC

@IBOutlet private weak var viewPopupUI:UIView!
@IBOutlet var btnClose: UIButton!

override func viewDidLoad() {
    super.viewDidLoad()

   self.showViewWithAnimation()
}

@IBAction func btnCloseAction(_ sender: Any) {

    self.hideViewWithAnimation()
}

 //MARK: - Animation Method
private func showViewWithAnimation() {

    self.view.alpha = 0
    self.viewPopupUI.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)

    UIView.animate(withDuration: 0.3) {
        self.viewPopupUI.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)
        self.view.alpha = 1
    }
}

private func hideViewWithAnimation() {

    UIView.animate(withDuration: 0.3, animations: {

        self.viewPopupUI.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)
        self.view.alpha = 0

    }, completion: {
        (value: Bool) in

        self.removeFromParent()
        self.view.removeFromSuperview()
    })
}

Call popup

let popupVC = storyboard?.instantiateViewController(withIdentifier: "SchoolEventGoingPopup_VC") as! SchoolEventGoingPopup_VC
    popupVC.strId =  self.dictEventDetails?.object(forKey: "id") as? Int
    view.addSubview(popupVC.view)
    addChildViewController(popupVC)
