ios - 在 Web View 中加载拦截 javascript 文件
<p><p>我正在使用 <code>WKWebView</code> 制作网页 View 应用</p>
<pre><code>let url = NSURL(string: "http://www.example.com")
let request = NSURLRequest(url: url! as URL)
homeWebView.load(request as URLRequest)
</code></pre>
<blockquote>
<p>But I want to intercept some javaScript file of this website before it
loads to change functionality and make the app a bit native looking</p>
</blockquote>
<p>任何帮助将不胜感激。</p>
<p>谢谢。</p></p>

private var webView: UIWebView!

override func viewDidLoad() {
super.viewDidLoad()
// set the view controller title, navigation etc
self.loadWebPage()
}
func loadWebPage() {
let url = URL(string: "https://www.google.com.pk/")
// let localFileURL = URL(fileURLWithPath: Bundle.main.path(forResource: "ExampleHtmlFileName", ofType: "html", inDirectory: "HtmlFilesFolderName")!)
let myRequest = URLRequest(url: url!)
webView.loadRequest(myRequest)
}
//MARK: UIWebView Delegate
func webViewDidFinishLoad(_ webView: UIWebView) {
let jsScript = "exampleJSMethod()"
_ = webView.stringByEvaluatingJavaScript(from: jsScript)
}
}
</code></pre></p>
