有没有办法在WKWebView中加载本地图像？

<img src="local_image.jpg" alt="Local Image">

if let image = UIImage(named: "local_image.jpg") {
    if let imageData = image.pngData()?.base64EncodedString(options: .endLineWithLineFeed) {
        let htmlString = "<img src='data:image/png;base64,\(imageData)' alt='Local Image'>"
        webView.loadHTMLString(htmlString, baseURL: nil)
    }
}

if let imagePath = Bundle.main.path(forResource: "local_image", ofType: "jpg") {
    let fileURL = URL(fileURLWithPath: imagePath)
    webView.loadFileURL(fileURL, allowingReadAccessTo: fileURL)
}
