Question

我试试：

let body = "<body>.. ANYTHING ..</body>"
self.webView.loadHTMLString(body, baseURL: NSURL(string: "www.google.com")!)

或

self.webView.loadHTMLString(body, baseURL: nil)

如果我打印：

 self.webView.stringByEvaluatingJavaScriptFromString("document.body.outerHTML")!

此印刷品：

<body></body>

那不是我的整个HTML ..

有什么想法吗？

身体来自

NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) {(response, data, error) in
                            if error == nil {
    let body = NSString(data: data, encoding: NSUTF8StringEncoding)
}

是的，不是空的

Answer 1

如果你打电话

self.webView.stringByEvaluatingJavaScriptFromString("document.body.outerHTML")!

调用loadHTMLString之后的

是期望的行为，因为UIWebView异步加载内容。在UIWebView中设置viewDidLoad的委托，然后在委托方法中调用此evaluateJS ...

func webViewDidFinishLoad(webView: UIWebView) 
{
    let body = self.webView.stringByEvaluatingJavaScriptFromString("document.body.outerHTML")!
    println(body)
}

Answer 2

将您的html文件保存到您的项目中，然后在webview中加载html，请参阅下面的内容，如果这不起作用请检查： - link

import UIKit


class ViewController: UIViewController {
@IBOutlet weak var webView: UIWebView!

    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        let localfilePath = NSBundle.mainBundle().URLForResource("test", withExtension: "html");
        let myRequest = NSURLRequest(URL: localfilePath!);
        webView.loadRequest(myRequest);
        //or use as below 
        let myHTMLString:String! = "<h1>Hello Pizza!</h1>"
        webView.loadHTMLString(myHTMLString, baseURL: nil)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }



}

iOS UIWebView loadHTMLString不起作用
