通过XIB视图显示WebView ViewController

Question

我有一个XIB视图和一个按钮，但是当我尝试将其配置为带有WebView的ViewController时，它会显示一些错误。

xib文件：

class popUpView: UIView, UITextFieldDelegate {

@IBOutlet weak var payNowPopUp: UIButton!
@IBOutlet weak var priceTextFieldPopUp: UITextField!

required init?(coder: NSCoder) {
    super.init(coder: coder)
}

override init(frame: CGRect) {
    super.init(frame: frame)
    xibSetup(frame:CGRect(x: 0, y: 0, width: frame.width, height: frame.height))
}

func xibSetup(frame: CGRect){
    let view = loadXib()
    view.frame = frame
    addSubview(view)
    popUpViewInterface.layer.cornerRadius = 10
}

func loadXib() -> UIView {
    let bundle = Bundle(for: type(of: self))
    let nib = UINib(nibName: "popUpView", bundle: bundle)
    let view = nib.instantiate(withOwner: self, options: nil).first as? UIView
    return view!
}

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    
    priceTextFieldPopUp.resignFirstResponder()
}


func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    
    priceTextFieldPopUp.resignFirstResponder()
    
    return true
}


@IBAction func payNowToWebView(_ sender: Any) {
    
    guard let mainTabBarController = self.storyboard?.instantiateViewController(withIdentifier: "paymentWebView")
    else {
        return
    }
    
    mainTabBarController.modalPresentationStyle = .custom
    self.present(mainTabBarController, animated: true, completion: nil)
    }
}

@ibaction func paynowtowebview（_ sender：any）{}}我想在单击按钮时显示一个viewController popupview'没有成员'故事板'和类型'popupView'的值没有成员'rathing'rathing'

Answer 1

这样做（请记住将“主”替换为故事板的名称）：

@IBAction func payNowToWebView()  {

        let storyboard: UIStoryboard = UIStoryboard (name: "Main", bundle: nil)
        let vc: paymentWebView = storyboard.instantiateViewControllerWithIdentifier("paymentWebView") as! PaymentWebView
        let currentController = self.getRootVC()
        currentController?.presentViewController(vc, animated: false, completion: nil)

    }

func getRootVC() -> UIViewController? {

    if let rootController = UIApplication.shared.keyWindow?.rootViewController {
        var currentController: UIViewController! = rootController
        while( currentController.presentedViewController != nil ) {
            currentController = currentController.presentedViewController
        }
        return currentController
    }
    return nil

}

存在是一种方法，故事板是uiviewController中的两个属性

， self.storyboard用uistoryboard（name：“ yourname”，nil）但对于呈现最常见的是在该视图中具有委托弱变量，该视图引用了内部视图的VC，或者您可以获取应用程序的窗口root vc，然后vc.present（.....
