ios - WKWebView 全屏而不是框架？

Question

我是 Swift 3.0 的新手，我需要一些帮助...

我正在尝试创建一个应该显示网站的框架。该网站不应填满整个 View ，而应仅填满框架。每次我启动应用程序时，网站都会填满整个屏幕，而不仅仅是框架......:(

这是我的代码:

import UIKit
import WebKit

class ViewController: UIViewController, WKUIDelegate {


    @IBOutlet weak var webView: WKWebView!

    override func loadView() {
        let webConfiguration = WKWebViewConfiguration()
        webView = WKWebView(frame: .zero, configuration: webConfiguration)
        webView.uiDelegate = self
        view = webView
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        let myURL = URL(string: "https://www.google.com/")
        let myRequest = URLRequest(url: myURL!)
        webView.load(myRequest)
    }
}

我想要的:

为具有相等填充的 webview 添加约束( anchor )。

用 Storyboard布局试试这个:

从您的文件中删除 loadView() 代码:

或者以编程方式尝试:

import UIKit
import WebKit

class WebKitController: UIViewController {

    @IBOutlet weak var webView: WKWebView!

    override func viewDidLoad() {
        super.viewDidLoad()
        let myURL = URL(string: "https://www.google.com/")
        let myRequest = URLRequest(url: myURL!)
        setupWKWebViewConstraints()
        webView.load(myRequest)
    }

    // add constraints to your web view
    func setupWKWebViewConstraints() {

        let paddingConstant:CGFloat = 30.0

        webView.translatesAutoresizingMaskIntoConstraints = false

        webView.topAnchor.constraint(equalTo: self.view.topAnchor, constant: paddingConstant).isActive = true
        webView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor, constant: -paddingConstant).isActive = true
        webView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor, constant: paddingConstant).isActive = true
        webView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor, constant: -paddingConstant).isActive = true
    }

}
