c# - 无法创建 xamarin.ios native 控件包装器

Question

我正在尝试创建此 iOS native 控件的 xamarin 包装器。 https://github.com/ECSlidingViewController/ECSlidingViewController 。

我遵循那里的说明http://docs.xamarin.com/guides/ios/advanced_topics/binding_objective-c/binding_walkthrough/ 。
我创建了 iOS 绑定(bind)项目，但无法构建项目。有错误:

Error BI1018: btouch: No [Export] attribute on property ECSliding.ECSlidingViewController.IsAnimated (BI1018) (ECSlidingBinding)

或

Error BI1018: btouch: No [Export] attribute on property ECSliding.ECSlidingViewController.ContainerView (BI1018) (ECSlidingBinding)

您能解释一下可能出现的问题吗？

问题是 series of bugs在 Xamarin.iOS 中，当从绑定(bind)项目中的协议(protocol)继承时，如下所示:

public partial interface ECSlidingViewController :
    IUIViewControllerContextTransitioning,
    IUIViewControllerTransitionCoordinator, 
    IUIViewControllerTransitionCoordinatorContext {

在解决此问题之前，请尝试删除所有这些接口(interface):

public partial interface ECSlidingViewController {
