如何在Monotouch中绑定NSObject <EAAccessoryDe​​legate>？

我有以下的Obj-C .h，绑定的正确方法是什么？

@interface iSmart : NSObject<EAAccessoryDelegate>{ id<iSmartDelegate> delegate; } @property(nonatomic, assign) id<iSmartDelegate> delegate; -(id)init; @end __________________________________________________________________________________________ @class iSmart; @protocol iSmartDelegate <NSObject> -(void) iSmartDidConnect; -(void) iSmartDidDisconnect; -(void) cardStatusChanged:(unsigned char)status; @end __________________________________________________________________________________________ 

在这一刻，我有这个协议和接口：

 [BaseType (typeof(NSObject))] [Model] interface iSmartDelegate { [Export("iSmartDidConnect")] void iSmartDidConnect(); [Export("iSmartDidDisconnect")] void iSmartDidDisconnect(); [Export("cardStatusChanged:")] void CardStatusChanged(Byte status); } [BaseType (typeof (EAAccessoryDelegate), Delegates=new string [] { "WeakDelegate" }, Events=new Type [] { typeof (iSmartDelegate)})] interface iSmart { //@property(nonatomic, assign) id<iSmartDelegate> delegate; [Export("delegate"), NullAllowed] NSObject WeakDelegate { get; set; } [Wrap("WeakDelegate")] iSmartDelegate Delegate { get; set; } //-(id)init; [Export("init")] NSObject init(); } 

当我尝试在Xamarin Studio 错误BI0000中生成项目时出现此错误：意外错误 – 请在http://bugzilla.xamarin.com （BI0000）上提交错误报告，

谢谢

协议只在你的ApiDefinition中内联，所以你EAAccessoryDelegate在你的iSmart定义中声明EAAccessoryDelegate的几个方法：

 [BaseType (typeof(NSObject))] interface iSmart : EAAccessoryDelegate{ //bind the protocol here [Export ("accessoryDidDisconnect:")] void AccessoryDidDisconnect (EAAccessory accessory); } 

对于绑定委托，请看http://docs.xamarin.com/guides/ios/advanced_topics/api_design#Delegates

[UPDATE 2013-02-26]你的委托绑定看起来不错，除了应该编组为.NET byte的本地unsigned char ，因为.NET chartypes是2字节长以适合Unicode字符。

[UPDATE 2013-02-27]另外，正如你最近添加到你的问题，正确的方式来绑定一个构造函数是这样的（见http://docs.xamarin.com/guides/ios/advanced_topics/binding_objective -c_libraries ）：

 [Export ("init")] IntPtr Constructor ();
