如何在swift中阻止我们的应用程序的缩放模式

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {
    var webView: WKWebView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let webConfiguration = WKWebViewConfiguration()
        webView = WKWebView(frame: view.bounds, configuration: webConfiguration)
        webView.navigationDelegate = self
        view.addSubview(webView)
        
        let url = URL(string: "https://example.com")
        let request = URLRequest(url: url!)
        webView.load(request)
    }
    
    func webView(_ webView: WKWebView, shouldStartLoadWith request: URLRequest, navigationType: WKNavigationType) -> Bool {
        guard navigationType == .other else {
            return true
        }
        
        if let urlString = request.url?.absoluteString, urlString.contains("scale") {
            // 禁用缩放
            webView.scrollView.minimumZoomScale = 1
            webView.scrollView.maximumZoomScale = 1
            
            // 或者使用JavaScript禁用缩放
            let disableZoomScript = "var meta = document.createElement('meta'); meta.name = 'viewport'; meta.content = 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no'; var head = document.getElementsByTagName('head')[0]; head.appendChild(meta);"
            webView.evaluateJavaScript(disableZoomScript, completionHandler: nil)
        }
        
        return true
    }
}
