目标c不加载xamarin形式的ios

Question

我正在构建我的第一个目标c库绑定。我正在跟踪微软的这文档。我已经成功地从IronSource.framework中创建了一个fat二进制文件，并使用objective生成了apidefinition和structs，并将我的二进制文件添加到其中。

完成之后，我将绑定库添加到我的xamarin.ios项目中。当我试图从公开的API创建一个类的新实例时，我会得到一个错误。

无法找到类型或命名空间名称'IronSource‘(您是缺少使用指令还是程序集引用？)股票顾问的备份版本(版本1.6\版本代码37\StockAdviserCode\Stock\Stock\Stock.iOS\AdControlViewRenderer.cs 'AdControlViewRenderer.BannerWrapper‘)没有实现继承的抽象成员'ISBannerDelegate.DidClickBanner()’Stock.iOS D:股票顾问的备份版本\版本1.6\版本代码37\StockAdviserCode\Stock\Stock\Stock.iOS\AdControlViewRenderer.cs

我认为我的目标c库和xamarin.ios项目没有正确链接。

我的绑定项目名是IronSource，我的xamarin窗体ios项目名是Stock.iOS。

因此，我能够通过向Xamarin.ios添加胖二进制文件使其工作，并将构建类型从“不复制”更改为“始终复制”，然后使用-cxx -gcc_flags "-L${ProjectDir} -lIronSource -force_load ${ProjectDir}/IronSource.a将链接器添加到胖二进制文件中。

我用这 GitHub回购作为指导。

总的来说，为了设置IronSoruce，我必须在引用中添加dll，将本机框架添加到本机引用，将fat二进制添加到projectdir，并将链接器添加到fat二进制。
