swift2 - 将本地 css & js 文件加载到 WKWebView

Question

在 Swift 2.1.1 和 Xcode 7.1 中，
我的代码使用 WKWebView 并从本地文件加载 index.html，但无法加载 index.css 和其他 javascript 文件，如 head 标签所示。

我最好的猜测是baseURL不正确，如果是这样，我怎样才能正确设置baseURL？谢谢

import UIKit
import WebKit

class ViewController: UIViewController {
@IBOutlet var containerView: UIView! = nil  //allows the class to refrence WKWebView
var webView: WKWebView?

override func loadView() {
    super.loadView()

    self.webView = WKWebView()
    self.view = self.webView!
}

override func viewDidLoad() {
    super.viewDidLoad()

    let HTMLDocumentPath = NSBundle.mainBundle().pathForResource("index", ofType: "html")
    let HTMLString: NSString?

    do {
        HTMLString = try NSString(contentsOfFile: HTMLDocumentPath!, encoding: NSUTF8StringEncoding)
        let baseUrl  = NSURL.fileURLWithPath("")
        webView!.loadHTMLString(HTMLString as! String, baseURL: baseUrl)

    } catch {
        HTMLString = nil
    }
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

}

   <head>
      <meta charset="UTF-8">
      <title>RRR</title>
      <link rel="stylesheet" href="jquery.mobile-1.4.5.css"/>
      <link rel="stylesheet" href="index.css"/>
      <script src="jquery-1.11.3.js"></script>
      <script src="jquery.mobile-1.4.5.js"></script>
      <meta name="viewport" content="width=device-width"/>
   </head>

在此处阅读有关文件 url 的信息后，我能够解决问题。

这是代码

import UIKit
import WebKit

class ViewController: UIViewController {
    @IBOutlet var containerView: UIView! = nil  //allows the class to reference WKWebView
    var webView: WKWebView?

    override func loadView() {
        super.loadView()

        self.webView = WKWebView()
        self.view = self.webView!
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        let baseUrl = NSURL(string: "file:///<yourFilePath>/abc/")
        let path = NSBundle.mainBundle().pathForResource("abc/index", ofType: "html")
        let HTMLString: NSString?

        do {
            HTMLString = try NSString(contentsOfFile: path!, encoding: NSUTF8StringEncoding)
            webView!.loadHTMLString(HTMLString as! String, baseURL: baseUrl )

        } catch {
            HTMLString = nil
        }
    }
}
