Question

我使用UIWebView并想加载以下网址：

http://feratel.lueneburger-heide.de/lhg/de/accommodation/detail/LUH/8634e147-e13d-40f5-8954-2ac40cfea2a7/romantik_hotel_bergström?customHeader=true

http://feratel.lueneburger-heide.de/lhg/de/accommodation/detail/LUH/8af6d1fd-af6d-4765-8025-9eb8fa05ea42/hotel%20undeloher%20hof?customHeader=true

在移动版Safari和UIWebView中加载上述网址时，会得到不同的结果。不是在呈现页面方面，而是向用户显示的最终页面是不同的。

以下是我在iOS7中使用的代码：

class ViewController: UIViewController, UIWebViewDelegate, NSURLConnectionDataDelegate {
  @IBOutlet weak var webView: UIWebView!
  var request: NSURLRequest!
  var urlString: String!
  private var isDone: Bool = false
  private var failedRequest: NSURLRequest!

  override func viewDidLoad() {
    super.viewDidLoad()

    var userAgent = ["UserAgent": "mozilla/5.0 (iphone; cpu iphone os 7_0_2 like mac os x) applewebkit/537.51.1 (khtml, like gecko) version/7.0 mobile/11a501 safari/9537.53"]
    NSUserDefaults.standardUserDefaults().registerDefaults(userAgent as [NSObject : AnyObject])


    urlString = "https://buchung.salonmeister.de/ort/301655/menue/#offerId=907601&venueId=301655"
    request = NSURLRequest(URL: NSURL(string: urlString)!)
    webView.delegate = self
  }

  override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    self.webView.loadRequest(self.request)
  }

  // MARK: UIWebViewDelegate

  func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
    println("shouldStartLoadWithRequest()")

    if !isDone {
      isDone = false

      println("shouldStartLoadWithRequest() 111")
      failedRequest = request
      webView.stopLoading()
      var connection = NSURLConnection(request: request, delegate: self, startImmediately: true)
      connection!.start()
      //      NSURLConnection(request: request, delegate: self)
      return false
    }
    println("shouldStartLoadWithRequest() -----------------------")
    return true
  }

  func webViewDidStartLoad(webView: UIWebView) {
    println("webViewDidStartLoad()")
  }

  func webViewDidFinishLoad(aWebView: UIWebView) {
    println("webViewDidFinishLoad()")
  }

  func webView(webView: UIWebView, didFailLoadWithError error: NSError) {
    println("webView(): didFailLoadWithError(): \(error)")
  }

  // MARK: NSURLConnectionDataDelegate

  func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge) {
    println("connection willSendRequestForAuthenticationChallenge")

    if challenge.previousFailureCount == 0 {
      self.isDone = true
      println("x1")
      let credential: NSURLCredential = NSURLCredential(forTrust: challenge.protectionSpace.serverTrust!)
      challenge.sender.useCredential(credential, forAuthenticationChallenge: challenge)

    }
    else {
      println("x2")
      challenge.sender.cancelAuthenticationChallenge(challenge)
    }
  }

  func connection(connection: NSURLConnection, didReceiveResponse response: NSURLResponse) {
    println("connection didReceiveResponse")
    self.isDone = true

    connection.cancel()
    self.webView.loadRequest(self.failedRequest)
  }

  func connection(connection: NSURLConnection, canAuthenticateAgainstProtectionSpace protectionSpace: NSURLProtectionSpace) -> Bool {
    println("connection canAuthenticateAgainstProtectionSpace")
    return protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust
  }
}

如何强制UIWebView加载移动Safari之类的网址？

编辑：以下是我使用以下网址时的外观：

http://feratel.lueneburger-heide.de/lhg/de/accommodation/detail/LUH/8af6d1fd-af6d-4765-8025-9eb8fa05ea42/hotel%20undeloher%20hof?customHeader=true

UIWebView中的

：

以下是它在移动Safari中的外观：

Answer 1

这对我有用：

[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://feratel.lueneburger-heide.de/lhg/de/accommodation/detail/LUH/8634e147-e13d-40f5-8954-2ac40cfea2a7/romantik_hotel_bergstrom?customHeader=true"]]];

我需要在网址

中将'ö'替换为'o'字符

UIWebView是否加载了与移动Safari不同的URL？
