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

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 URL 与所有 safari 和其他浏览器完美配合。 （包括 iOS 11 移动版 Safari）

• 该网址适用于除 iOS 11 以外的所有 iOS 版本。

• 我尝试在 UIWebView 和 WKWebView 上打开 URL，但同样的问题发生在两者上。即 URL 在接近完成时停止加载，并且 然后什么都不会发生。

这是我目前尝试过的

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。

//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;

}

@结束

@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];

}

我已经分析了你的代码是好的，你需要检查图像格式。当我使用带有图像 url 链接的波纹管代码时工作正常。

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.
    }


}

WkWebview 是最近引入的，而 UIWebView 现已正式弃用。 这是苹果论坛上发布的同一问题的链接。苹果工作人员目前正在解决崩溃问题。 enter link description here

https://forums.developer.apple.com/thread/90411 还尝试在您的项目中添加 WKWebView.framework。 和运输安全。 希望这些信息对您有所帮助。
