我一直工作在一个简单的应用程序，使一个网站，学生可以参加考试的网页视图。
所以基本上我的问题是，当学生完成后，他们必须点击一个按钮，将发送答案。会显示一个弹出，使他们确认。 https://i.stack.imgur.com/5GhB8.png除了它不会显示出来。当按钮被按下没有任何反应。它完美的作品在Safari和我已经注意到，它适用于已弃用的WebView（UIWebView的），但我一直在努力使其在WKWebView工作。
我绝对没有SWIFT专家，所以我很抱歉，如果答案很简单。我一直在试图找到我的问题的一些答案，但我不知道如何实现它。
预先感谢您的任何帮助，
import UIKit
import WebKit
class webViewController: UIViewController {
@IBOutlet weak var webview: WKWebView!
override func viewDidLoad() {
super.viewDidLoad()
let lien = "***"
if let url = URL(string: lien) {
let request = URLRequest(url: url)
_ = webview.load(request);
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
我也面临类似的问题，我的是用于连接Facebook不会在WKWebView显示弹出，但在Safari浏览器工作正常。
此代码是导致该问题。
- (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures {
//This condition was causing the problem while trying to get popup
if (!navigationAction.targetFrame.isMainFrame) {
[webView loadRequest:navigationAction.request];
}
return nil;
}
我把它改成下面的代码和它的工作
- (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures {
if (navigationAction.targetFrame == nil) {
NSURL *tempURL = navigationAction.request.URL;
NSURLComponents *URLComponents = [[NSURLComponents alloc] init];
URLComponents.scheme = [tempURL scheme];
URLComponents.host = [tempURL host];
URLComponents.path = [tempURL path];
if ([URLComponents.URL.absoluteString isEqualToString:@"https://example.com/Account/ExternalLogin"]) {
WKWebView *webViewtemp = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:configuration];
webViewtemp.UIDelegate = self;
webViewtemp.navigationDelegate = self;
[self.view addSubview:webViewtemp];
return webViewtemp;
} else {
[webView loadRequest:navigationAction.request];
}
}
return nil;
}
斯威夫特版本：
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
if navigationAction.targetFrame == nil {
let tempURL = navigationAction.request.url
var components = URLComponents()
components.scheme = tempURL?.scheme
components.host = tempURL?.host
components.path = (tempURL?.path)!
if components.url?.absoluteString == "https://example.com/Account/ExternalLogin" {
let webViewtemp = WKWebView(frame: self.view.bounds, configuration: configuration)
webViewtemp.uiDelegate = self
webViewtemp.navigationDelegate = self
self.view.addSubview(webViewtemp)
return webViewtemp
} else {
webView.load(navigationAction.request)
}
}
return nil
}
希望这可以帮助你
我试过轮的其他方式，它为我工作。下面是代码：创建的WebView的实例
fileprivate var webView: WKWebView?
初始化实例，并分配给它来查看。
override func loadView() {
webView = WKWebView(frame: .zero, configuration: WKWebViewConfiguration())
webView?.uiDelegate = self
webView?.navigationDelegate = self
view = webView
}
此后，只需添加以下的委托方法：
func webView(_: WKWebView, createWebViewWith _: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures _: WKWindowFeatures) -> WKWebView? {
self.webView?.load(navigationAction.request)
return nil
}
瞧！一切都将工作一样UIWebView。
注意：您将无法点击网站上的几个环节，因为他们将是HTTP，而不是HTTPS。默认块未确保所有HTTP请求WKWebView。
要绕过，只需要添加NSExceptionAllowsInsecureHTTPLoads在true文件info.plist。
我的解决办法是实施WKUIDelegate和添加功能不同的场景（警报），所述web视图可呈现：
extension WKWebViewController: WKUIDelegate {
func webView(_ webView: WKWebView, runJavaScriptAlertPanelWithMessage message: String, initiatedByFrame frame: WKFrameInfo, completionHandler: @escaping () -> Void) {
let alertController = UIAlertController(title: nil, message: message, preferredStyle: .actionSheet)
alertController.addAction(UIAlertAction(title: NSLocalizedString("OK", comment: "OK button"), style: .default, handler: { (action) in
completionHandler()
}))
present(alertController, animated: true, completion: nil)
}
func webView(_ webView: WKWebView, runJavaScriptConfirmPanelWithMessage message: String, initiatedByFrame frame: WKFrameInfo, completionHandler: @escaping (Bool) -> Void) {
let alertController = UIAlertController(title: nil, message: message, preferredStyle: .actionSheet)
alertController.addAction(UIAlertAction(title: NSLocalizedString("OK", comment: "OK button"), style: .default, handler: { (action) in
completionHandler(true)
}))
alertController.addAction(UIAlertAction(title: NSLocalizedString("Cancel", comment: "Cancel button"), style: .default, handler: { (action) in
completionHandler(false)
}))
present(alertController, animated: true, completion: nil)
}
func webView(_ webView: WKWebView, runJavaScriptTextInputPanelWithPrompt prompt: String, defaultText: String?, initiatedByFrame frame: WKFrameInfo, completionHandler: @escaping (String?) -> Void) {
let alertController = UIAlertController(title: nil, message: prompt, preferredStyle: .actionSheet)
alertController.addTextField { (textField) in
textField.text = defaultText
}
alertController.addAction(UIAlertAction(title: NSLocalizedString("OK", comment: "OK button"), style: .default, handler: { (action) in
if let text = alertController.textFields?.first?.text {
completionHandler(text)
} else {
completionHandler(defaultText)
}
}))
alertController.addAction(UIAlertAction(title: NSLocalizedString("Cancel", comment: "Cancel button"), style: .default, handler: { (action) in
completionHandler(nil)
}))
present(alertController, animated: true, completion: nil)
}
}
