Xamarin:绑定ios协议/委托不能访问在structs.cs中定义的枚举

我目前正在为EDQueue库创建ios绑定.

该Structs.cs文件看起来像这样:

using System;
using ObjCRuntime;

namespace EDQueue
{


    // => Enums attributed with[NativeAttribute] must have an underlying type of `long` or `ulong`
    [Native]
    public enum EDQueueResult : long
    {
        Success = 0,
        Fail,
        Critical
    }

}

该ApiDefinition.cs文件类似于:

using System;
using Foundation;
using ObjCRuntime;

namespace EDQueue
{
    // typedef void (^EDQueueCompletionBlock)(EDQueueResult);
    delegate void EDQueueCompletionBlock(EDQueueResult result);

    // ETC....

    // @protocol EDQueueDelegate 
    [Protocol, Model]
    [BaseType(typeof(NSObject))]
    interface EDQueueDelegate
    {
        // @optional -(EDQueueResult)queue:(EDQueue *)queue processJob:(NSDictionary *)job;
        [Export("queue:processJob:")]
        EDQueueResult Queue(EDQueue queue, NSDictionary job);

        //// @optional -(void)queue:(EDQueue *)queue processJob:(NSDictionary *)job completion:(EDQueueCompletionBlock)block;
        //[Export("queue:processJob:completion:")]
        //void Queue(EDQueue queue, NSDictionary job, EDQueueCompletionBlock completeBlock);

    }

    // ETC...
}

如上所述,产生以下错误: 错误CS0426:文件类型'EDQueue'(CS0426)(EDQueue)中不存在类型名称'EDQueueResult'EDQueueDelegate.g.cs

抛出错误时,该文件如下所示:

//
// Auto-generated from generator.cs, do not edit
//
// We keep references to objects, so warning 414 is expected

#pragma warning disable 414

using System;
using System.Drawing;
using System.Diagnostics;
using System.ComponentModel;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using System.Runtime.CompilerServices;
using UIKit;
using GLKit;
using Metal;
using MapKit;
using ModelIO;
using SceneKit;
using Security;
using AudioUnit;
using CoreVideo;
using CoreMedia;
using QuickLook;
using Foundation;
using CoreMotion;
using ObjCRuntime;
using AddressBook;
using CoreGraphics;
using CoreLocation;
using AVFoundation;
using NewsstandKit;
using CoreAnimation;
using CoreFoundation;

namespace EDQueue {
    [Protocol (Name = "EDQueueDelegate", WrapperType = typeof (EDQueueDelegateWrapper))]
    [ProtocolMember (IsRequired = false, IsProperty = false, IsStatic = false, Name = "Queue", Selector = "queue:processJob:", ReturnType = typeof (EDQueue.EDQueueResult), ParameterType = new Type [] { typeof (global::EDQueue.EDQueue), typeof (NSDictionary) }, ParameterByRef = new bool [] { false, false })]
    public interface IEDQueueDelegate : INativeObject, IDisposable
    {
    }
// ETC...
}

但是,如果我删除或注释掉该[Protocol, Model]位,则库会构建没有错误.

如果我用第二个函数取消注释,我也会得到类似的错误EDQueueCompletionBlock,最终依赖于EDQueueResult枚举.

该Structs.cs文件的生成操作设置为ObjcBindingCoreSource.

真的很感激任何帮助.谢谢!
