swift2 – 将本地css和js文件加载到WKWebView中

在 Swift 2.1.1& Xcode 7.1
我的代码使用WKWebView并将index.html加载为本地文件,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()
}

}

<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>

在阅读了有关文件URL的 here之后,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 refrence 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
    }
}
 
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}
}
