我正在尝试使用Xamarin.iOS绑定库绑定objective-c协议。我遇到的问题是生成界面在编译时对我的任何C＃代码都不可见。我正在使用documentation section on Xamarin讨论“MonoTouch 7.0中的新功能”协议绑定过程。
这是我的目标-c协议：
@protocol SomeApplicationDelegate <NSObject>
- (void)displayAboutView;
- (void)displaySettingsView;
- (void)displayMessagesView;
- (void)presentSetup;
@end
我的ApiDefinition看起来像这样：
[Model, Protocol]
[BaseType (typeof (NSObject))]
interface SomeApplicationDelegate {
[Export("displayAboutView")]
void DisplayAboutView();
[Export("displaySettingsView")]
void DisplaySettingsView();
[Export("displayMessagesView")]
void DisplayMessageView();
[Export("presentSetup")]
void PresentSetup();
}
interface ISomeApplicationDelegate {}
[BaseType(typeof(NSObject))]
interface SomeApplicationDelegateTool {
[Export ("getProtocol")]
ISomeApplicationDelegate GetProtocol ();
}
最后，我正在尝试在AppDelegate上实现生成的接口/协议：
[Register ("AppDelegate")]
public partial class AppDelegate : UIApplicationDelegate, ISomeApplicationDelegate
{
// class-level declarations
public override UIWindow Window {
get;
set;
}
public UITabBarController TabBarcontroller {
get;
private set;
}
public override void OnResignActivation (UIApplication application)
{
}
public override void DidEnterBackground (UIApplication application)
{
}
public override void WillEnterForeground (UIApplication application)
{
}
public override void WillTerminate (UIApplication application)
{
}
public void DisplayAboutView() {
}
public void DisplaySettingsView(){
}
public void DisplayMessageView(){
}
public void PresentSetup(){
}
}
这是构建日志的输出：

我是创建绑定的新手，所以我不确定如何弄清楚到底出了什么问题。据我所知，看起来我已经正确地遵循了这些步骤。而且我似乎拥有xcode项目中所有相同的框架引用。
我的linkWith.cs有这个：
[assembly: LinkWith ("libSome.a", LinkTarget.Simulator | LinkTarget.ArmV7 | LinkTarget.ArmV7s, ForceLoad = true, Frameworks = "MobileCoreServices CFNetwork MessageUI CoreGraphics CoreLocation MapKit QuartzCore SystemConfiguration UIKit Foundation AddressBook AddressBookUI", LinkerFlags = "-lxml2 -lz")]
我在连接libxml2和libz库时遇到了问题，但我认为现在没问题。
根据我对该过程的理解以及文档所说的内容，我的界面似乎应该可用。 Intellisense显示库名称空间下可用的ISomeApplicationDelegate，但在编译时我得到构建错误。我不知道从哪里开始。有什么想法吗？
