xamarin.ios

问题 Just updated to the lastest version of Xamarin studio and Xamarin.iOS. Now I am getting this error: Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. Well, its not even an error actually.

问题 wondering if anyone can help, the text on the webView is too small, I have an HTML that I have NO control over. How can I increase the size? I have tried Xamarin forms: Webview content default size is too small but did not work for me as the page does not load at all. Is this a bug? Am I missing something? Any suggestions <WebView VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand"> <WebView.Source> <HtmlWebViewSource Html="{Binding HtmlSource}" /> </WebView.Source> </WebView>
