Webview总是在ios Xamarin.Forms中返回黑屏 [英] Webview always return blank screen in ios Xamarin.Forms

问题描述

我正在使用此代码示例加载具有https协议的页面，但无法使其正常工作:

I'm using this code sample to load a page with https protocol, but I'm unable to make it work: https://github.com/TheRealAdamKemp/AuthenticatedWebView

我使用" https://www.google.com 作为网页，但没有使用.我还尝试在Info.plist中添加应用程序安全权限".我总是得到空白页.

I'm using "https://www.google.com" as web page but nothing. I've also tried to add App Security Permission in Info.plist. I always get a blank page.

有人可以向我解释为什么吗?

Can anyone explain to me why?

推荐答案

如果您响应WebView.Navigating事件，请确保不要将其args.Cancel设置为true(如果加载的页面是WevView.Source). WebView.Navigating的iOS实现在加载WebView.Source时触发，而Android实现则不触发.如果在相关页面为WebView.Source时将args.Cancel设置为true，则WebView将为空白.

If you are responding to the WebView.Navigating event, be sure to not set its args.Cancel to true if the page loaded is the WevView.Source. The iOS implementation of WebView.Navigating fires when the WebView.Source is loaded but the Android implementation does not. If you set args.Cancel to true when the page in question is the WebView.Source, the WebView will be blank.
