MAUI .NET 8 iOS加载SVG时SkiaSharp方法缺失异常解决咨询

迁移Xamarin Forms项目到MAUI .NET 8后，加载SVG图片时抛出以下异常：

Unhandled Exception:
System.MissingMethodException: Method not found: SkiaSharp.SKMatrix SkiaSharp.SKMatrix.MakeTranslation(single,single)

触发异常的代码片段：

using (var stream = GetImageStream(svgName.Replace(".PNG", ".svg").Replace(".png", ".svg"), imagePath))
{
    if (stream != null)
    {
        svg = new SkiaSharp.Extended.Svg.SKSvg();
        svg.Load(stream);
        SVGComponentImage[$"{key}"] = svg;
    }
}

这个异常是SkiaSharp系列包版本不兼容导致的：.NET 8对应的SkiaSharp包版本已更新，而你使用的SkiaSharp.Extended.Svg版本可能仍适配旧版SkiaSharp，找不到新版中已变更的SKMatrix.MakeTranslation方法。

解决步骤：

• 统一更新SkiaSharp相关包：在NuGet包管理器中卸载所有旧版SkiaSharp、SkiaSharp.Views.Maui、SkiaSharp.Extended.Svg包，重新安装适配.NET 8的最新稳定版，确保所有包版本完全一致。
• 清理缓存并重建项目：删除项目目录下的bin和obj文件夹，执行dotnet clean命令清理后，重新编译运行。
• 检查依赖冲突：打开项目.csproj文件，确认所有SkiaSharp相关包版本统一；若存在间接依赖的旧版包，可通过指定版本号强制覆盖。
