将 UIImage 加载到 WebView Swift 4

Question

而不是像这样从 URL 加载 WebView

override func viewDidLoad() {
    super.viewDidLoad()

    let url = URL(string: imageUrl.urlString)
    let request = URLRequest(url: url!)
    webView.load(request)

}

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

    view = webView
}

如何将 UIImage 加载到 Swift 4 中的 WebView？

Answer 1

试试这样的东西。

let html = "<html><img src=\"datadb/DestinationGuide/Images/YourImage.png\"/> </html>"

//Save this html in `DocumentDirectory`
let saveHTML = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0].appendingPathComponent("temp.html")

try? html.data(using: .utf8)!.write(to: saveHTML)

//Now load this `temp.html` file in webView
webView.loadRequest(URLRequest(url: saveHTML))
