I use a UIWebView and want to load the following urls:
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
When you load the above urls in mobile Safari and in a UIWebView you get different results. Not in terms of rendering the page, but the final page which is shown to the user is a different one.
Here is the code I use with iOS7:
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
}
}
How can I force a UIWebView to load URLs like mobile Safari does?
Edit: Here is how it looks when I use the following url:
http://feratel.lueneburger-heide.de/lhg/de/accommodation/detail/LUH/8af6d1fd-af6d-4765-8025-9eb8fa05ea42/hotel%20undeloher%20hof?customHeader=true
in UIWebView:
and here is how it looks in mobile Safari:
This worked for me :
[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"]]];
I need to replace the 'ö' with 'o' character in the URL

I have xcode 9.1 with swift 4 and i'm unable to authenticate using webview anymore. here is my code :
import UIKit
protocol AuthViewControllerDelegate{
func getAccessToken(_ code: String)
}
class AuthViewController: UIViewController, NSURLConnectionDelegate {
#IBOutlet weak var navItem: UINavigationItem!
#IBOutlet weak var webView: UIWebView!
var delegate: AuthViewControllerDelegate?
override func viewDidLoad() {
super.viewDidLoad()
var link: "https://home.nest.com/login/oauth2?client_id=…"
if let encodeURL = link.URLEncodedString(), let url = URL(string: encodeURL) {
webView.loadRequest(URLRequest(url: url))
}
}
override var preferredStatusBarStyle : UIStatusBarStyle {
return .lightContent
}
#IBAction func CancelPressed(_ sender: UIBarButtonItem) {
self.dismiss(animated: true, completion: nil)
}
func webView(_ webView: UIWebView, shouldStartLoadWithRequest request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if let url = request.url?.absoluteString, url.contains("code=") {
if let code = getQueryStringParameter(url,param: "code"){
self.dismiss(animated: true, completion: { () -> Void in
UIApplication.shared.isNetworkActivityIndicatorVisible = false
self.delegate?.getAccessToken(code)
})
}
}
return true
}
func webViewDidStartLoad(_ webView: UIWebView){
UIApplication.shared.isNetworkActivityIndicatorVisible = true
}
func webViewDidFinishLoad(_ webView: UIWebView){
UIApplication.shared.isNetworkActivityIndicatorVisible = false
}
func getQueryStringParameter(_ url: String?, param: String) -> String? {
if let url = url, let urlComponents = URLComponents(string: url), let queryItems = (urlComponents.queryItems) {
return queryItems.filter({ (item) in item.name == param }).first?.value!
}
return nil
}
}
And here is the error i'm getting in the log :
2017-11-07 20:49:30.836087+0000 TestApp[1851:1259046] TIC TCP Conn

And i already have this into my .plist file :
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
NB: The same code was working perfectly with swift 3.2
Check if your htpps:// is right, had the same problem, fixed after changing url.
Adding NSAllowsArbitraryLoads into .plist file resolves the error
NSURLConnection error - code - 1200
where my development language is Objective C.
I use UIWebView to load the remote url, the page is blank because the network is unavailable. After network is available ,i reload the UIWebView, but the page is still blank.
How can i solve it?
Try this
func reloadRequest() {
if let url = URL(string: "https://stackoverflow.com") {
let request = URLRequest(url: url);
self.loadRequest(request);
}
}
Load web view with request again, like:
if let url = URL(string: "https://www.google.com") {
let request = URLRequest(url: url)
wvWebView.loadRequest(request)
}
Here is sample code.
#IBOutlet var wvWebView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
wvWebView.delegate = self
reloadWebview()
}
// call this function to reload web view.
func reloadWebview(){
if let url = URL(string: "https://www.google.com") {
let request = URLRequest(url: url)
wvWebView.loadRequest(request)
}
}
// Webview Delegates
func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
print("\n\n**** webView:shouldStartLoadWithRequest: \(request.url) \(navigationType)")
return true
}
func webViewDidStartLoad(_ webView: UIWebView) {
print("webViewDidStartLoad")
}
func webViewDidFinishLoad(_ webView: UIWebView) {
print("webViewDidFinishLoad")
}
func webView(_ webView: UIWebView, didFailLoadWithError error: Error) {
print("error description - \(error.localizedDescription)")
}
I made an iOS app with Xcode and Swift.
I want to open specific hyperlinks in Safari browser, there others in the WebView itself.
To reach this, I'll have to check when an hyperlinks gets clicked.
This is the code I have so far:
//
// PushViewController.swift
// App
//
//
import UIKit
class PushViewController: UIViewController, UIWebViewDelegate {
#IBOutlet var openpushmessage: UIWebView!
var weburl:String = "http://www.example.com"
override func viewDidLoad() {
super.viewDidLoad()
let url: NSURL = NSURL(string: weburl)!
let requestURL: NSURLRequest = NSURLRequest(URL: url)
openpushmessage.loadRequest(requestURL)
}
override func webView(_ webView: UIWebView, shouldStartLoadWithRequest request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if navigationType == .linkClicked
{
print("You clicked a hypelink!")
}
return true
}
}
The code in viewDidLoad() opens the loads the main URL (http://www.example.com) from my server. That works fine.
override fun webView[…] should detect if a hyperlink is clicked and then print("You clicked a hypelink!").
But unfortunately I'm getting the following errors:
What am I doing wrong? How to get rid of these errors?
please try
for swift 3.0
public func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool
{
if navigationType == .linkClicked
{
}
return true;
}
swift 2.2
internal func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool
{
if navigationType == .LinkClicked
{
}
return true;
}
This is the working solution (Xcode 7.3.1 and Swift 2.2):
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if request.URL?.query?.rangeOfString("target=external") != nil {
if let url = request.URL {
UIApplication.sharedApplication().openURL(url)
return false
}
}
return true
}
Many thanks to danhhgl from freelancer.com!
I think you can solve with this code:
function reportBackToObjectiveC(string)
{
var iframe = document.createElement("iframe");
iframe.setAttribute("src", "callback://" + string);
document.documentElement.appendChild(iframe);
iframe.parentNode.removeChild(iframe);
iframe = null;
}
var links = document.getElementsByTagName("a");
for (var i=0; i<links.length; i++) {
links[i].addEventListener("click", function() {
reportBackToObjectiveC("link-clicked");
}, true);
}
in ios code:
if ([[[request URL] scheme] isEqualToString:#"callback"]) {
[self setNavigationLeavingCurrentPage:YES];
return NO;
}

I have a iOS app which has a uiwebview where it opens a website, but any link clicked in the webview opens up in Safari. In my code bellow, it get a memetype error on the line "webView.load(request)". Can you give me some code so I can fix this? Thanks! (I need to use a UIWebView instead of a WKWebView)
class VideosViewController : UIViewController, UIWebViewDelegate {
#IBOutlet weak var webView : UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
guard let url = URL(string: "http://example.com") else { return }
let request = URLRequest(url: url)
webView.load(request)
}
func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if navigationType == .linkClicked {
guard let url = request.url else { return true }
UIApplication.shared.open(url, options: [:], completionHandler: nil)
return false
}
return true
}
}
Try to call webView.loadRequest(request). This function has only one URLRequest parameter.

I've added a "rewind" back button to my UIWebview via the main.storyboard and connected it here on my view with a backButton func:
class ViewController: UIViewController, UIWebViewDelegate {
#IBOutlet weak var webView: UIWebView!
var detailItem: NSURL?
var grabData = false
override func viewDidLoad() {
super.viewDidLoad()
webView.delegate = self
self.navigationController?.toolbarHidden = false;
}
#IBAction func backButton(sender: AnyObject) {
self.webView.goBack()
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
if let url = self.detailItem {
webView.loadRequest(NSURLRequest(URL: url))
}
}
func webView(webView: UIWebView, shouldStartLoadWithRequest request:
NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if grabData {
grabData = false
return true
} else {
grabData = true
manuallyLoadPage(request)
return false
}
}
func manuallyLoadPage(request: NSURLRequest) {
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request) {
(data, response, error) invar html = NSString(data: data, encoding: NSUTF8StringEncoding) as String
html = html.stringByReplacingOccurrencesOfString("</head>", withString: "<styles><link rel='stylesheet' type='text/css' href='link-to-styles.css' media='all'></styles></head>", options: NSStringCompareOptions.CaseInsensitiveSearch, range: nil)
self.webView.loadHTMLString(html, baseURL: response.URL!)
}
task.resume()
}
My back button doesn't do anything when clicked and I want it to show the previous webpage. I think it has something to do with how I am intercepting the session and manually loading the WebView. Maybe it doesn't know what the original base url is? Something else?
