Question

今天早上这个让我疯狂。我想将一些本地html加载到Web视图中：

class PrivacyController: UIViewController {

    @IBOutlet weak var webView:UIWebView!

    override func viewDidLoad() {
        let url = NSURL(fileURLWithPath: "privacy.html")
        let request = NSURLRequest(URL: url!)
        webView.loadRequest(request)
    }
}

html文件位于我项目的根文件夹中，但位于组内。 webview对我来说是空白的。任何想法都错了吗？我在xcode 6.1上并在我的iphone 6上运行这个例子。

Answer 1

要检索应用资源的网址，您应该使用URLForResource类的NSBundle方法。

Swift 2

let url = NSBundle.mainBundle().URLForResource("privacy", withExtension:"html")

Swift 3

let url = Bundle.main.url(forResource: "privacy", withExtension: "html")

Answer 2

Swift 3：输入安全

@IBOutlet weak var webView: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Adding webView content
    do {
        guard let filePath = Bundle.main.path(forResource: "myFile", ofType: "html")
            else {
                // File Error
                print ("File reading error")
                return
        }

        let contents =  try String(contentsOfFile: filePath, encoding: .utf8)
        let baseUrl = URL(fileURLWithPath: filePath)
        webView.loadHTMLString(contents as String, baseURL: baseUrl)
    }
    catch {
        print ("File HTML error")
    }
}

请记住：NS = Not Swift：]

Answer 3

// Point UIWebView
@IBOutlet weak var webView: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    //load a file
    var testHTML = NSBundle.mainBundle().pathForResource("privacy", ofType: "html")
    var contents = NSString(contentsOfFile: testHTML!, encoding: NSUTF8StringEncoding, error: nil)
    var baseUrl = NSURL(fileURLWithPath: testHTML!) //for load css file

    webView.loadHTMLString(contents, baseURL: baseUrl)

}

Answer 4

Swift 3 3 行：）

if let url = Bundle.main.url(forResource: "privacy", withExtension: "html") {
    webview.loadRequest(URLRequest(url: url))
}

Answer 5

Swift版本2.1

这种情况还包括编码

// load HTML String with Encoding
let path = NSBundle.mainBundle().pathForResource("policy", ofType: "html")
do {
    let fileHtml = try NSString(contentsOfFile: path!, encoding: NSUTF8StringEncoding)
    webView.loadHTMLString(fileHtml as String, baseURL: nil)
}
catch {

}

Answer 6

将本地HTML文件添加到项目中并将该文件命名为home.html，然后使用NSURL对象创建NSURLRequest。在将请求传递给Web视图之后，它会将请求的URL加载到Web视图中，如果您不使用storyboard，请将uiwebview添加到视图控制器视图中，如下面的代码所示。

 override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        let localfilePath = NSBundle.mainBundle().URLForResource("home", withExtension: "html");
        let myRequest = NSURLRequest(URL: localfilePath!);
        myWebView.loadRequest(myRequest);
        self.view.addSubview(myWebView)
    }

Answer 7

这对我有用：

@IBOutlet weak var mWebView: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    mWebView.loadRequest(NSURLRequest(URL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("fineName", ofType: "html")!)))

}

在 info.plist 文件中添加了App Transport Security Settings Dictionary类型。还为应用传输安全设置添加了子键Allow Arbitrary Loads，类型为Boolean，值为YES。

Here是教程。

对于Swift 3（Xcode 8）

mWebView.loadRequest(URLRequest(url: URL(fileURLWithPath: Bundle.main.path(forResource: "test/index", ofType: "html")!)))

Answer 8

您可以在UIWebView中加载html字符串或本地html文件。

HTML字符串：

func loadHtmlCode() {
    let htmlCode = "<html><head><title>Wonderful web</title></head> <body><p>wonderful web. loading html code in <strong>UIWebView</strong></></body>"
    webView.loadHTMLString(htmlCode, baseURL: nil)
}

HTML文件：

func loadHtmlFile() {
    let url = NSBundle.mainBundle().URLForResource("contactus", withExtension:"html")
    let request = NSURLRequest(URL: url!)
    webView.loadRequest(request)
}

Answer 9

这是 Swift 4

的简洁版本

1）添加导入import WebKit

2）在项目中添加WebKit.framework

@IBOutlet weak var webView: WKWebView!

if let filePath = Bundle.main.url(forResource: "FILE_NAME", withExtension: "html") {
  let request = NSURLRequest(url: filePath)
  webView.load(request as URLRequest)
}

Answer 10

对于swift 3使用此：

do
    {
        let testHTML = Bundle.main.path(forResource: "about", ofType: "html")
        let contents =  try NSString(contentsOfFile: testHTML!, encoding: String.Encoding.utf8.rawValue)
        let baseUrl = NSURL(fileURLWithPath: testHTML!) //for load css file

        mWebView.loadHTMLString(contents as String, baseURL: baseUrl as URL)
    }
    catch
    {

    }

Answer 11

这对我有用（Xcode 8，Swift 3）

@IBOutlet weak var webViewer：UIWebView！

override func viewDidLoad() {
    super.viewDidLoad()

    let localfilePath = Bundle.main.url(forResource: "homeInfo", withExtension: "html");
    let myRequest = NSURLRequest(url: localfilePath!);
    webViewer.loadRequest(myRequest as URLRequest);
    self.view.addSubview(webViewer)
}

Answer 12

Swift 4.2，Xcode 10.1，WKWebView从文件加载HTML。不推荐使用UIWebView。

在运行于iOS 8及更高版本的应用中，请使用WKWebView类，而不要使用UIWebView。

import WebKit

@IBOutlet weak var webView: WKWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    let localFilePath = Bundle.main.url(forResource: "document_terms_of_use", withExtension: "html")
    let request = NSURLRequest(url: localFilePath!)
    webView.load(request as URLRequest)
}

Answer 13

swift 4.2和5：

  digraph {
      rankdir=TB;
      newrank = true;
      ...

不要忘记添加此let webView = WKWebView(frame: CGRect(x: 0, y: 0, width: 1024, height: 768)) let url = URL(string: PERS_Path) webView?.navigationDelegate = self webView?.uiDelegate = self webView!.loadFileURL(url!, allowingReadAccessTo: url!) self.view. addSubview(webView)

使用swift将本地html加载到UIWebView中
