将本地css和js文件加载到WKWebView中

在Swift 2.1.1和Xcode 7.1中
我的代码使用WKWebView并将index.html加载到本地文件中,但无法加载index.css和其他javascript文件,如head标记所示.

我最好的猜测是baseURL不正确,如果是这样,我该如何正确设置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()
}

}

   
      
      
      
      
      
      
      


1> Fred J...：
在这里阅读了一些关于文件URL的内容后,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:////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
        }
    }
}

        
嗨,您能否准确描述您使用的路径而不是`file:/// /abc /`？谢谢
