问题 I am trying to include some custom css within a webview on xamarin forms so the website being used can be customized with css styles, changing colors or other css style classes. I have done this before using native code in Xcode and Android Studio, however this project is using xamarin forms and visual studio.

问题 I'm making app with using Xamarin forms. I want to draw a smooth path (spline) with SKPath, but I am unable to find a simple way to achieve this. Skiasharp does not support it currently unless I make path smoothly myself. Thanks. 回答1: SkiaSharp supports cubic Bezier curves.
