如何在Xamarin.Forms ios中实现统一的ads
我正在尝试在xamarin.forms应用程序中添加统一广告。我在Android上成功地实现了这些功能，但在iOS上却很难实现 对于Android，我已经创建了一个自定义的渲染器和一个xml布局来保存广告内容 对于ios，我试着遵循这一点-github.com/xamarin/GoogleApisForiOSComponents/blob/master/docs/Firebase/AdMob/但它不是很清楚，只在Swift/Objective C中提供帮助，我正在寻找C 编辑- Xamarin.表格 in.xaml如何在Xamarin.Forms ios中实现统一的ads,xamarin.forms,xamarin.ios,unifiednativeadview,Xamarin.forms,Xamarin.ios,Unifiednativeadview,我正在尝试在xamarin.forms应用程序中添加统一广告。我在Android上成功地实现了这些功能，但在iOS上却很难实现 对于Android，我已经创建了一个自定义的渲染器和一个xml布局来保存广告内容 对于ios，我试着遵循这一点-github.com/xamarin/GoogleApisForiOSComponents/blob/master/docs/Firebase/AdMob/但它不是很清楚，只在Swift/Objective C中提供帮助，我正在寻找C 编辑- Xamarin.
