我想将本地html文件加载到字符串变量中。我不知道该怎么做。请帮我。我发现下面的链接，但它从在线网址加载它。 Swift & UIWebView element to hide

Answer 1

将html复制到项目目录中并使用以下代码：

@IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
    super.viewDidLoad()

        var htmlFile = NSBundle.mainBundle().pathForResource("MyHtmlFile", ofType: "html")
        var htmlString = try? String(contentsOfFile: htmlFile!, encoding: NSUTF8StringEncoding)
        webView.loadHTMLString(htmlString!, baseURL: nil)


}

在Swift 3中：

    let htmlFile = Bundle.main.path(forResource:"MyHtmlFile", ofType: "html")
    let htmlString = try? String(contentsOfFile: htmlFile!, encoding: String.Encoding.utf8)
    webView.loadHTMLString(htmlString!, baseURL: nil)

我建议使用optional chaining而不是如上所述强行展开htmlString。

您可以编写一些这样的实用方法并获取html字符串并将其加载到webview。我在这里使用了URL方法

   private func getHTML() -> String {
        var html = ""
        if let htmlPathURL = Bundle.main.url(forResource: "test", withExtension: "html"){
            do {
                html = try String(contentsOf: htmlPathURL, encoding: .utf8)
            } catch  {
                print("Unable to get the file.")
            }
        }

        return html
    }

Swift 3语法：

    guard
        let file = Bundle.main.path(forResource: "agreement", ofType: "html"), 
        let html = try? String(contentsOfFile: file, encoding: String.Encoding.utf8)
    else {
        return
    }
    webView.loadHTMLString(html, baseURL: nil)

简单回答

 let indexPath = Bundle.main.path(forResource: "index", ofType: "html", inDirectory: "/")
        if let indexPath = indexPath
        {
            do
            {
                let htmlContent = try String(contentsOfFile: indexPath, encoding: String.Encoding.utf8)

                let base = Bundle.main.resourceURL 
                self.webView.loadHTMLString(htmlContent, baseURL: base)

            }
            catch let err as NSError
            {
                print(err.debugDescription)
            }
        }
