Question

我有一个不会通过iOS WKWebView显示的网页链接。如何通过WKWebView显示此类链接？

似乎只有3个版本的https://www.google.com和http://www.apple.com会显示使用http：//或https：//的网页。如何通过WKWebView加载其他网页？（注意：所有网站都在不使用http：//语法的情况下加载到Google Chrome和Apple Safari中。）

以下是ViewDidLoad的代码：

          @IBOutlet weak var myWebkitView: WKWebView!
          override func viewDidLoad() {
          super.viewDidLoad()


        `if let myUrl = URL(string:"https://www.ihs-us.org")`
         {

          let myURLRequest = URLRequest(url: myUrl)
          myWebkitView.load(myURLRequest)

         }

         }

      Below links works only for Apple and Google. 
     https://www.google.com will shows a Web site
     http://www.apple.com also will shows its web site
     schools.nyc.gov/SchoolPortals/08/X282 -- causes a crash
     ihs-us.org // causes a crash, and does not show a web page

Answer 1

所有浏览器都将http：//附加到网址（如果不存在），通常如果网页支持SSL，则会重定向https：//网站。我开发了一个供内部使用的浏览器，任何URL用户都输入，我将http：//附加到URL。最简单的方法是

class func getValidURLFromString(_ urlString: String)->String{        
    if !urlString.hasPrefix("http://") && !urlString.hasPrefix("https://"){
        return "http://" + urlString
    }
    else {
        return urlString
    }
}

<强>编辑： ViewController代码

import UIKit
import WebKit
class ViewController: UIViewController, WKUIDelegate {

@IBOutlet weak var webView: WKWebView!
override func viewDidLoad() {
    super.viewDidLoad()
    let urlString = isValidURLFormat("schools.nyc.gov/SchoolPortals/08/X282")
    let myURL = URL(string: urlString)
    let myRequest = URLRequest(url: myURL!)
    webView.load(myRequest)
}
func isValidURLFormat(_ urlString: String) -> String {
    if !urlString.hasPrefix("https://") && !urlString.hasPrefix("http://"){
        return "http://" + urlString
    }
    return urlString }

}

Plist设置

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSAllowsArbitraryLoadsInWebContent</key>
        <true/>
    </dict>

试试这个 -

import UIKit
import WebKit

class ViewController: UIViewController{

    @IBOutlet var webView: WKWebView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let urlString = "ihs-us.org"

        if urlString.hasPrefix("https://") || urlString.hasPrefix("http://"){
            let myURL = URL(string: urlString)
            let myRequest = URLRequest(url: myURL!)
            webView.load(myRequest)
        }else {
            let correctedURL = "http://\(urlString)"
            let myURL = URL(string: correctedURL)
            let myRequest = URLRequest(url: myURL!)
            webView.load(myRequest)
        }

    }

}

schools.nyc.gov/SchoolPortals/08/X282 -

对于ihs-us.org -

您只需执行以下步骤 -

打开项目的Info.plist文件。右键单击它并添加一行。

然后在你的（原样）中添加这两行 -
