iOS UIWebView loadHTMLString不起作用

Question

我尝试：

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

要么

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

如果我打印：

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

此打印：

<body></body>

那不是我的整个HTML ..

有任何想法吗？

注意

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，不为空

Answer 1

如果你打电话

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

loadHTMLString是，由于UIWebView异步加载内容，因此在调用loadHTMLString后loadHTMLString情况。 在viewDidLoad设置UIWebView的委托，然后在委托方法中调用此EvaluationJS ...

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

将您的html文件保存到您的项目中，然后将其加载到webview中，请参阅下文，如果这样做没有帮助，请检查此：- 链接

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.
    }
