在加载WebView之前在Xcode13中删除白色屏幕？

Question

需要删除白屏幕，然后在iOS中加载网页视图，尝试不透明的网页视图。即使在添加了Splash屏幕和启动屏幕之后，在加载Webview之前，我仍然会得到白色的飞溅。

import UIKit
import WebKit
class HomeViewController: UIViewController, WKUIDelegate {
    
    var webView: WKWebView!
     
    override func loadView() {
        let webConfiguration = WKWebViewConfiguration()
        webView = WKWebView(frame: .zero, configuration: webConfiguration)
        webView.uiDelegate = self        
        view = webView
        webView.isOpaque = false
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()

        let webConfiguration = WKWebViewConfiguration()
        webView = WKWebView(frame: .zero, configuration: webConfiguration)
        webView.translatesAutoresizingMaskIntoConstraints = false
        let myURL = URL(string:"https://google.com")
        let myRequest = URLRequest(url: myURL!)
        

        
        view.addSubview(webView)
        webView.load(myRequest)

        NSLayoutConstraint.activate([
            webView.topAnchor.constraint(equalTo: view.topAnchor),
            webView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
            webView.leftAnchor.constraint(equalTo: view.leftAnchor),
            webView.rightAnchor.constraint(equalTo: view.rightAnchor)
        ])}
}

Answer 1

//Xcode13 13

webView.isOpaque = false; 
webView.backgroundColor = UIColor.clear;

Answer 2

您试过删除webView的背景色吗？

webView.backgroundColor = .clear

Answer 3

你试过吗

self.webView.scrollView.backgroundColor = .clear
