How to load URL in UIWebView in Swift?

Question

I have the following code:

UIWebView.loadRequest(NSURLRequest(URL: NSURL(string: "google.ca")))

I am getting the following error:

'NSURLRequest' is not convertible to UIWebView.

Any idea what the problem is?

Answer 1

Try This

let url = NSURL (string: "http://www.apple.com");
myWebView.loadRequest(NSURLRequest(URL: url!));

Answer 2

Try this:

1. Add UIWebView to View.

2. Connect UIWebview outlet using assistant editor and name your "webview".

3. UIWebView Load URL.

   @IBOutlet weak var webView: UIWebView!
   
   override func viewDidLoad() {
      super.viewDidLoad()
       // Your webView code goes here
      let url = URL(string: "https://www.example.com")
      let requestObj = URLRequest(url: url! as URL)
      webView.load(requestObj)
   }
   

And run the app!!

Answer 3

You can load a page like this :

let url: URL = URL(string:"https://google.com")!
webView.loadRequest(URLRequest.init(url: url))

Or the one-line approach :

webView.loadRequest(URLRequest.init(url: URL(string: "https://google.com")!))

webView is your outlet var.

Answer 4

Swift 3 doesn't use NS prefix anymore on URL and URLRequest, so the updated code would be:

let url = URL(string: "your_url_here")
yourWebView.loadRequest(URLRequest(url: url!))

Answer 5

Easy,Tested and working 100%

Import webkit :

import WebKit

Assign IBOutlet to webview:

var webView : WKWebView!

set delegate:

class ViewController: UIViewController , WKNavigationDelegate{

Write code on viewDidLoad():

// loading URL :
let myBlog = "https://stackoverflow.com/users/4600136/mr-javed-multani?tab=profile"
let url = NSURL(string: myBlog)
    let request = NSURLRequest(url: url! as URL)

    // init and load request in webview.
    webView = WKWebView(frame: self.view.frame)
    webView.navigationDelegate = self
    webView.load(request as URLRequest)
    self.view.addSubview(webView)
    self.view.sendSubview(toBack: webView)

Write delegate methods:

//MARK:- WKNavigationDelegate

func webView(webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation!, withError error: NSError) {
print(error.localizedDescription)
}


 func webView(webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
print("Strat to load")
    }

 func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!) {
print("finish to load")
}

look like:

Answer 6

In Swift 4 or 4.2 You can use like:

1. Add WKWebView & connect to you view comtroller.

2. Your view is like bellow:

    import UIKit
    import WebKit
   
   class ViewController: UIViewController {
   
      @IBOutlet weak var wkwebview: WKWebView!
   
       override func viewDidLoad() {
          super.viewDidLoad()
   
         let request = URLRequest(url: URL(string: "**your URL**")!)        
         wkwebview?.load(request)
   
     }
   
   }
   

3. Allow Allow Arbitrary Loads true info.plist

     <key>NSAppTransportSecurity</key>
        <dict>
          <key>Allow Arbitrary Loads</key>
             <true/>
       </dict>
   

   Note info.plist will look like bellow
