Question

我的网址

https://app.educationgalaxy.com/games/ipadgame.html?retries=3&name=blastoff&rocket=3&level=2&score=0&gameTimer=150

我的发现

该网址适用于所有Safari和其他浏览器。（包括iOS 11手机游戏）
该URL适用于iOS 11以外的所有iOS版本。
我尝试在UIWebView和WKWebView上打开URL，但两者都发生了同样的问题。即URL在完成时停止加载那时没有任何事情发生。

这是我到目前为止所尝试的内容

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {

    // Objects
    var webView: WKWebView!

    override func viewDidLoad() {
        super.viewDidLoad()

        setupWebView()
        loadUrl()
    }

    func setupWebView() {

        let prefs = WKPreferences()
        prefs.javaScriptEnabled = true
        let config = WKWebViewConfiguration()
        config.preferences = prefs

        webView = WKWebView(frame: view.frame, configuration: config)
        webView.navigationDelegate = self
        view.addSubview(webView)
    }

    func loadUrl() {

        webView.navigationDelegate = self
        let url = URL(string: "https://app.educationgalaxy.com/games/ipadgame.html?retries=3&name=blastoff&rocket=3&level=2&score=0&gameTimer=150")!
        var request = URLRequest(url: url)
        request.cachePolicy = .reloadRevalidatingCacheData
        webView.load(request)
    }

    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        print(webView.url!)

    }

    func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {

        print(webView.url!)
    }

    func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {

        print("error  - \(error)")
    }

}

感谢您的帮助。

我已经分析了你的代码是好的，你需要检查图像格式。当我使用波纹管代码与图像url链接工作正常。

import UIKit
import WebKit

class ViewController: UIViewController  ,WKNavigationDelegate {


    var webView: WKWebView!

    override func viewDidLoad() {
        super.viewDidLoad()

        setupWebView()
        loadUrl()
    }

    func setupWebView() {

        let prefs = WKPreferences()
        prefs.javaScriptEnabled = true
        let config = WKWebViewConfiguration()
        config.preferences = prefs

        webView = WKWebView(frame: view.frame, configuration: config)
        webView.navigationDelegate = self
        view.addSubview(webView)
    }

    func loadUrl() {

        webView.navigationDelegate = self
       // let url = URL(string: "https://app.educationgalaxy.com/games/ipadgame.html?retries=3&name=blastoff&rocket=3&level=2&score=0&gameTimer=150")!

         let url = URL(string: "https://upload.wikimedia.org/wikipedia/commons/2/2d/Snake_River_%285mb%29.jpg")!


        var request = URLRequest(url: url)
        request.cachePolicy = .reloadRevalidatingCacheData
        webView.load(request)
    }

    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        print(webView.url!)

    }

    func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {

        print(webView.url!)
    }

    func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {

        print("error  - \(error)")
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

最近推出了WkWebview，现在正式弃用UIWebView。这是Apple论坛上发布的相同问题的链接。苹果工作人员目前正在查明崩溃。 enter link description here

https://forums.developer.apple.com/thread/90411 还尝试在项目中添加WKWebView.framework。和运输安全。希望这些信息可以帮到你。

//添加plist文件

<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSExceptionDomains</key>
<dict>
    <key>google.com</key>
    <dict>
        <key>NSExceptionAllowsInsecureHTTPLoads</key>
        <true/>
        <key>NSIncludesSubdomains</key>
        <true/>
    </dict>
</dict>

 if WKWebView don't not support then declare .m file below code:



#import <WebKit/WebKit.h>

@interface WebScannerViewController()
{

 WKWebView *webView;

}

@end

@implementation WebScannerViewController -（void）viewDidLoad {

[super viewDidLoad];
webView.hidden=YES;

webView.UIDelegate = self;
webView.navigationDelegate = self;
self.loadingSign.hidden = NO;


    webView.frame=CGRectMake(0, 94, Width, Height-128);
    webView = [[WKWebView alloc] initWithFrame:self.view.bounds];
     webView.customUserAgent = @"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/601.6.17 (KHTML, like Gecko) Version/9.1.1 Safari/601.6.17";
    webView.navigationDelegate = self;
    NSURL *url = [NSURL URLWithString:@"https://app.educationgalaxy.com/games/ipadgame.html?retries=3&name=blastoff&rocket=3&level=2&score=0&gameTimer=150"];
    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
    [webView loadRequest:urlRequest];

}

Url在UIWebView和WKWebView上停止加载。仅在iOS 11上
