swift - Xamarin中的CGMutablePath

我正在尝试为我的xamarin.ios应用程序翻译此代码：
https://github.com/yourtion/YXWaveView/blob/master/YXWaveView/YXWaveView.swift
在线179：
let path = CGMutablePath()
我在Xamarin找不到CGMutablePath

最佳答案

objcCGMutablePathRef结构（或swift cgmutablepath类）由Xamarin.iOS包装为CGPath（CoreGraphics命名空间）。

var path = new CGPath();

Xamarin Macios/SRC/Coregraphics/cgpath.cs公司

public class CGPath : INativeObject, IDisposable {
        internal IntPtr handle;

        [DllImport (Constants.CoreGraphicsLibrary)]
        extern static /* CGMutablePathRef */ IntPtr CGPathCreateMutable ();

        public CGPath ()
        {
            handle = CGPathCreateMutable ();
        }

        [Mac(10,7)][iOS (5,0)]
        public CGPath (CGPath reference, CGAffineTransform transform)
        {
            if (reference == null)
                throw new ArgumentNullException ("reference");
            handle = CGPathCreateMutableCopyByTransformingPath (reference.Handle, ref transform);
        }

        [DllImport (Constants.CoreGraphicsLibrary)]
        extern static /* CGMutablePathRef */ IntPtr CGPathCreateMutableCopy (/* CGPathRef */ IntPtr path);

        public CGPath (CGPath basePath)
        {
            if (basePath == null)
                throw new ArgumentNullException ("basePath");
            handle = CGPathCreateMutableCopy (basePath.handle);
        }
