Question

我需要帮助绑定Xamarin中的PayPalMobile（objective-C）库。

我发现了几个PayPal绑定，但它们已过时并使用iOS8.x.我想将最新的PayPalMobile绑定到iOS9.2。

我跟踪Xamarin walkthrough绑定Objective-C库以帮助我绑定PayPalMobile库。

在演练之后，我将顶级头文件PayPalMobile.h传递给Objective Sharpie。我将Objective Sharpie生成的两个文件的内容（命名空间除外）复制到我的解决方案中并构建它。

建成后我收到了几个错误：

错误CS0246：找不到类型或命名空间名称“验证”。你错过了装配参考吗？（CS0246）

错误CS0246：找不到类型或命名空间名称“Native”。你错过了装配参考吗？（CS0246）

错误CS0579：属性'StaticAttribute'无法多次应用（CS0579）

现在，我的问题是：如何修复此错误？此外，属性：

BaseType，NullAllowed，Abstract，Wrap，Static，Verify，ConstantsInterfaceAssociation，StronglyTypedNSArray，PayPalPaymentViewControllerState，MethodToProperty

为红色，在当前上下文中不存在。我错过了一些资源吗？

假设上述错误是固定的。为了使用新的绑定，这将是一切吗？
