Blank screen when using http in webView iOS Swift

Question

I am new to Swift / iOS and am trying to use webView to be able to view a url. Searching this site and countless others I managed to be able to access google by using

var url = NSURL(string: "https://www.google.com")

This works fine with "https" but does not work if I use "http". Is the "s" a security setting? How can I view sites with a "URL scheme" of "http". Hope you can assist.

import UIKit
import WebKit
import Foundation

class ViewController: UIViewController {

    @IBOutlet var containerView : UIView? = nil

    var webView:WKWebView?

    //instatiating the webView
    override func loadView() {
        super.loadView()
        self.webView = WKWebView()
        self.view = self.webView
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        //Loading and showing a web-page
        var url = NSURL(string: "https://www.google.com")
        //var url = NSURL(string: "http://www.google.com")
        var req = NSURLRequest(URL:url!)
        self.webView!.loadRequest(req)
    }
}

Answer 1

编辑 info.plist 并添加 App Transport Security Settings 并添加到 Allow Arbitrary Loads 和 Boolean = yes

Answer 2

just add this line in your info.plist info.plist is an XML file so you can place this code more or less anywhere inside the file. this is the configuration to allow a specific domain to use HTTP instead of HTTPS:

 <key>NSAppTransportSecurity</key>
 <dict>
 <!--Include to allow all connections (DANGER)-->
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

Answer 3

Try with http://stackoverflow.com . it worked for me

var url = NSURL(string: "http://stackoverflow.com/")

        //var url = NSURL(string: "http://www.google.com")//Comment this

        var req = NSURLRequest(URL:url!)

        self.webView!.loadRequest(req)
